Z Score Biofeedback has Transformed
 the Field of Neurofeedback

What Our Clinicians Say about Using NeuroGuide and Neurofeedback...

NeuroGuide Z-Score training and the Symptom Checklist training have resulted in substantial improvement in patients.   For example, a stroke victim who after just 3 full cap coherence sessions regained use of his arm and was able to close his hand as if holding a baseball or a chronically depressed woman who after just two full cap sessions claimed she felt like new person; and, another chronically anxious woman who stated she wanted as much of this stuff as she could get because she felt so good.  Quite honestly, I have never seen this kind of rapid progress in certain patients with any other training format.  My guess is you have taken neurofeedback training to a "new level."

Attached is a summary of seven sessions of LNFB training with a young Marine combat veteran. Importantly, he is no longer taking any psychotropic medications and is going to start school next week. He told me today that he was feeling different but didn't know what to attribute it to. I showed him the session progress screen and his eyes welled up and said, "I guess I am better." I think he is too. Thanks for giving me the tools to help this youngster - as a retired Marine, being able to offer healing and hope to these kids is a big deal to me. Have a great week end.

I wanted to thank you for the opportunity to use Z score training. I have worked for ten years in neurofeedback and, while I have had good results, they do not compare to what I am getting now. Many of my patients report an immediate sense of calm when they are experiencing Z score training. It is as if the request that the brain communicate with itself better can be a much better challenge than asking the brain to improve at one or even two sites. My younger patients are often able to tolerate sitting still for the training because they feel immediately better and they want that feeling to continue. They complain of boredom much less often.  Thanks again for your work. I feel Z score training is a big step toward helping to improve brains, one brain at a time.

I have put the surface Neurofeedback in use strait away and it seems to be an extremely valuable addition.  I am also getting the first modest results with LORETA Z-scores from one of my cleints who spent decades in therapy and was barely functional and is back to the Gym and full of new ideas and clarity that he professes not to have experienced for many years.

The parents of this young lady are pleased with a number of positive behaviors and overall attitude of their daughter.    This is a progress map of a 12 year old girl with generalized anxiety who has a traumatic background.  She started out having psychotherapy sessions for about 6 months and then began 19 Channel  Surface Neurofeedback.    Her clinical symptoms were:  irritability, lack of focus and concentration, sadness, nightmares and anxiety. 

NeuroFeedback Progress Charts

After 8 sessions, Her parents report that she has improved her grades, is doing better with her homework, is less irritable, more sociable at home with family members, has a significant decrease in nightmares and appears to be handling stress (mostly school and peers) much better.

Many thanks again for helping me to help my clients.

Many thanks for all you have contributed to the field and especially to my clients. 

Including the addition of your recommendations from the qEEG's I send you, over 90% of my veterans of police service reach remission of their DSM-IV duty-related PTSD symptoms.  They still require follow-up sessions including NF refresher which serves to pretty much eliminate any relapse and also help them get on with their lives.  This is truly remarkable given the number, intensity, and duration of PTSD symptoms they come with, the large number of significant accumulated traumatic experiences they have had, the number of co-morbid conditions accompanying the PTSD, and how badly many have been treated by police management.     

Hats off to you and personal regards

I Thought you might like to know last week did my first phase shift session with an autism spectrum teenager. Following week, last night, mother came in and said what did you do. Claimed her daughter was more conforming of requests and talked twice as much as ever before. I've worked with her for months, and while making progressing, have not seen this type of "step up" until now.

Very interesting and exciting.

Robert McCarthy, Ph.D.

I am very excited about this: my 17 year old client has suffered from a lot of mental challenges.  One that has lingered is amblyopia and a serious divergent strabismus.  We tried developmental optometry for years: eye patching, eye exercises, etc., along with traditional NFB.  But he continued to be monocular and one eye was shutting down which I verified by looking at his visal corrtex.  Last year he had eye surgery and the surgeon said that he would never have binocular vision because it was "too late".  Although his eyes were 'pulled together' he was still only seeing with one eye post surgery.  I did several sessions of LORETA and surface Z score training the past two months and last week he put 3D glasses on while looking at a 3D TV at best buy and he said "I can see 3D, I've never been able to before!"   We verified this and this of course indicates that he is seeing binocular?  He is shooting baskets in basketball like I have never seen too ... this is amazing.

Without your work all this would not be possible. Z-score NF is really great, it is helpful in so many cases - and I hear a lot of good reports from my workshop attendees. The approach isn´t too hard to understand and also its not too hard to teach to somebody. Good results can be made by everybody who really wants to learn. The fascinating thing is also when I feel that I also can be a part of this wonderful development.

Thomas Feiner, Ph.D.

While I knew your new program would be good, I had to share my  excitement and enthusiasm. Most impressive is the manner in which you  incorporated the technical sophistication of Neuroguide that already exists,  with the simplicity of clinical use. In essence, a breath of fresh air in an otherwise sometimes cumbersome and overwhelming technological world.  Despite the tremendous breadth and depth of being able to interface  with Neuroguide in so many ways, it [LORETA Z score biofeedback] can be easily learned by novices and  experienced practitioners alike in just a few hours. Now pre and post session data can even be converted into pre and post session  brain maps, and coherence changes carefully monitored from training  session to training session. Quite honestly, this is one of the most  exciting developments I have come across since entering the  neurofeedback field some twenty years ago.

Again, congratulations to you and your developers on a fantastic piece of work!

Robert McCarthy, Ph.D., Clinical Psychologist, Myrtle Beach, SC

I have been using Neuroguide’s Z Score surface program for approximately 7 months and have been very impressed with the results.  The following is a case of a 50 year old female who came to me in June of 2010 with major depressive DO even while medicated she had frequent bouts of crying, thoughts of suicide and days she could not get out of bed.  She was under a great deal of stress, separated from her husband and had a very stressful job.  Her medications were 225mg Effexor XR; 175mg of Wellbutrin and 1.5mg of Clonozepam.


She began 19 Channel Surface Z Score Neurofeedback in August of 2011, she was in a much more stable place and able to cope with stressful situations.  At the time of her first Neurofeedback session she had titrated down to 75mg of Wellbutrin and was going to continue to come off of that medication.  Since then she has titrated down to 1mg of clonozepam and continues to take 225mg Effexor.

She has shown remarkable improvement in her mood and her ability to cope with stress.  Today she feels that she does not need medication and will work with her Psychiatrist to titrate down the dosages of remaining Effexor and Clonozepam – her goal is to become medication free.  She does understand that that may not be possible, however, she is willing to settle with much less medic ation if she needs to.

Her Neurofeedback protocol began with Absolute Power, Phase and Coherence working to bring 3+ Z scores to zero.  She began to feel much calmer at 4 sessions.  At 13 sessions she had cut clonozepam to 1mg from 1.5 and was completely off of Wellbutrin.  She states that for the first time in 15 years she really feels her emotions, instead of a “numb or fog” feeling.

Along with her continued therapy and Neurofeedback sessions, she filled out the Walmyr self report tools:  Generalized Contentment Scale and the Index of Clinical Stress.  See below the continued improvement in both – she no longer meets criteria for either clinical condition.

My thanks and appreciation for all of your hard work to help me help my clients!!

Hi Bob,

This is a  25 year old female in her final year of law school.  Her reported symptoms were anxiety, depression and attention deficits.  Based on history and additional testing the latter seemed to be secondary to anxiety.  She received 13 sessions of LORETA NF using the Symptom Checklist. She gradually reported lower anxiety/depression and better ability to focus and attend.  She had been very worried about her ability to study for her final exams.  She did very well in fact and is now articling with a quite prestigious law firm.  I would likely have continued for a few more sessions but she is no longer living in Victoria .   She will return for  bi or tri weekly sessions if she feels she needs to.

I am using Neuroguide Z-Score training more and more with patients. This is primarily due to the fact that Symptom Checklist Training suggestions have resulted in substantial clinical improvement with patients.  For example, a stroke victim who after just 3 full cap coherence sessions regained use of his left arm and was able to close his hand as if holding a baseball (Continues to improve after 1 month); a chronically depressed woman who after just two full cap sessions claimed she felt like a new person (No longer lethargic, unmotivated); and, another chronically anxious woman who stated she wanted as much of this stuff as she could get because she felt so good (Going out, no longer hiding in house due to agoraphobia). I saw an extremely hyperactive boy this afternoon after just 2 full cap sessions using Symptom Checklist recommendations. His parents and all his teachers asked what medication he was  taking as they never seem him so calm. Observably, the change was dramatic.  

Quite honestly, I have never seen this kind of rapid progress in certain patients with any other system of training format. My guess is you have taken neurofeedback training to a "new level".


LORETA Neurofeedback and Neurofield.

The attached pdf shows  the clients change over several sessions.  Each session began with Neurofield and followed with LORETA Z score neurofeedback. Each session was 1 hour.

The clients have been very pleased with their progress.

Phil Jones, Ph.D.

I am here in Cancun and have been doing demos for some important people here in Mexico and treating a select few folks here with NG LORETA - I want to give you some feedback regarding the observations that continue to mount. First, I believe that what you have done with the software, the symptom checklist, etc., in the right hands, is one of the biggest breakthroughs in behavioral medicine - really worth a Nobel prize - and I am not kidding. Over the past 3 days I have treated anorexia, Autism, seizure disorders, and clinical depression, all with noticable results within hours of the sessions - the depression client is astounded, "I feel I am alive again!" (this statement after one session). I believe your imperative, "Location! Location! Location!" is paramount as well as following a hierarchy of brain networks from foundation to higher cortical function. Anyway, I just wanted to say that I recognize this enormous accomplishment and contribution you have made and I am confident - more so with every person I treat - that ultimately this will be a major source of relief for so many - thanks for your good work.

Hi Bob,

This client is a 57 year man, with a history of anxiety and depression stemming from events in his developmental years. He is normally very successful in his occupation. On this occasion he over-extended himself with responsibility and this resulted in an acute reaction involving anxiety and depression (November 2010). There have been similar episodes in the past, but this is the first time I have seen him. On presentation in August he had been off work for two months and unable to get out of bed in the mornings. It should be noted that he has always had obsessive tendencies.

The first maps were obtained August 2011, and high power is evident, mainly from 11 to 25 Hz. (see attached). Coherence and phase were OK. The second maps were taken on November 23, 2011 after 16 sessions of LORETA NF . It can be seen that the extent of surface high power is significantly reduced. Other intermediate maps tracked the changes. At that point, it was decided not to continue with therapy even though there remained some hot areas because the client had been successfully back to work for a month and was reporting no discomfort due to anxiety or depression. Also, we discussed the fact his obsessive tendency was what motivated him at work and led to his success. Thus, we terminated with the understanding that it his option to return if symptoms re-emerge. In general we stuck to the adage of matching symptoms to location. So far, so good.

I have run a couple of sessions with BrainSurfer.   Patients had 6 st. dev. LORETA Z scores before.    They were able to normalize attention and addiction networks and Delta-Alpha power in less than 30 minutes...WOW!   Thanks for the clue on rotating, and getting Brodmann areas.  It is just fabulous to watch metrics normalize and be able to move to another network live.

Cheers,  Grant Bright, Ph.D.





You will see the degree of attenuation of beta with no adverse reactions and clinically according to informants her level of functioning has improved as has mood stability and decreased reactivity.  We still have a long way to go.  This was done with straight LORETA and no other neuro modulation.  She has significant Axis I, II and III difficulties complicating matters enormously.  Shows you the power of LORETA.

Very good.  I have subjective improvement charted per session with qeeg data for each session. Of the first 100 I looked at I have 99% positive response (the one non-responder reported no subjective improvement but objective improvements were visible in his qEEG data). This is much better than I have gotten with pre-LORETA training.

I had an interesting testimonial yesterday from a client with a 42 year old brain injury and left hemiparesis: he looked at me with almost tears in his eyes and said, after 3 sessions “I was able to walk on the treadmill without holding onto the handrails for the first time in 42 years. I can plant my heel before my toes for the first time in 42 years. I can run for the first time in 42 years.”  How’s that for specific, targeted training? I almost cried too.

Dale S Foster, PhD, QEEGT, BCN Sr Fellow

Thank you for ALL of these wonderful clinical tools. I have about 20 patients now, and 100% of them are benefiting significantly. You are helping many people in this world, and you have helped me change the lives of my clients in ways I didn't know were possible!!!!

Just want to pass on to you all that the webinar #10--linking symptom checklist to surface neurofeedback--was a terrific review of how to conduct the whole process, from client assessment to applying principles of learning to train most efficiently.   I was most interested in learning just how the NG software assists in that and saw in the demonstration that it is a seamless process, that's very easy to implement and that follows all the primary principles of operant conditioning, from assessment and identifying the target behaviors to effective delivery of reinforcement.  Bob also explained very clearly the rationale of Z-tunes, which I think would be most useful.  All else can be accomplished separately, though less efficiently, using any assessment procedure and Z score software, but the Z tunes is unique to NG and seems like it should be particularly useful.  If anyone has had experiences with that I'd appreciate hearing how useful you've found it to be.  I highly recommend this webinar as in an introduction or refresher on all of these points. Kudos to Bob, yet again!!

I have been using QEEG/ Neuroguide since 2010, and I get so much praise and support from attorneys. Attorneys say that my QEEGs are sometimes the only thing that gives them the edge over their competitors. Sometimes because of work pressure, or because a patient has an unsuitable hairstyle for QEEG, I have sent out neuropsychological reports without a Q. Several attorneys have sent the patients right back with messages such as “How can you do a report without a QEEG?”.

Dr. Joachim Fl. Mureriwa

I have been using the surface Z-score neurofeedback for a few months now and I just want you to say that I’m absolutely astonished about the results I get! I have been doing a lot of neurofeedback on childeren with autism in a clinical setting for the last 7 years and have never seen these kind of results before. Thank you very much for this great software!

By the way, your program is having a big impact on the children and families in Palo Alto. A young man who recently came to me with symptoms of OCD has already experienced some symptom relief after only 10 sessions of Loreta neurofeedback!  He is no longer afraid to fly on planes, is not afraid to stay away from home (stayed away for several days and has never had been away for even a single night before), and slept 12 hours for the first time in his life (usually sleeps half this amount at best).  You are having a huge, positive impact on the world, and your program is allowing me and my team to do this one client at a time here in high tech Palo Alto. The computer engineers love it, because the automatically get the math (e.g., FFT), and it is a much better fit for most of them rather than medication.

All my best,

Oh by the way – we love what you’ve done with Brainsurfer. The HMI is much more intuitive and in keeping with NF2. Being able to capture the session data is also a real benefit. Brilliant! And thanks!

I  see a large number of children and use your program, ages 4-15 and I have had solid and rapid success with most.  One little girl went from having severe anxiety, throwing iPads at the wall and made dramatic changes in 10 sessions.  Another, the son of a vet with PTSD had not gone to school for months because of severe anxiety and GI issues and while he took a little longer he has since graduated and 6 months later is still doing well, going to school. His father a gulf war vet, disabled with PTSD and severe sleep disorder is now doing LORETA

RR had clinical symptoms related to a reported diagnosis  of early stages of dementia.  RR had trouble recalling words, was exceedingly forgetful, slow with speech.  On 4/10/2015 I performed a QEEG and did LORETA Z Score neurofeedback.  I utilized Neuroguide’s Symptom Checklist (SCL), matching symptoms to his QEEG, of executive function and working memory problems.  RR participated in 6 more sessions utilizing Neuroguide’s SCL and NF Tools.  The 8th session we returned to the original protocol based on the SCL of the 5/27/2015 QEEG. RR has shown significant improvement in executive functioning, memory retrieveal and organization skills as observed and self reported.  This chart shows the Brodmann areas (BAs) or regions of interest that were targeted during neurofeedback.  The top chart shows the percentage of rewards averaged for that particular session (number of times you could hear the sound and see the picture).  The bottom chart shows the average Z score for each BA targeted.  This particular graph shows areas as high as 3.8 std above the norm – by the 8th session all areas targeted fell to below 2 std deviations.
