Current Research Projects at Gray Matters

There are those who use research, and those who contribute to it. At Gray Matters, we are proud to do both.

Concussion

Our pioneering qEEG concussion baseline program is gathering unprecedented data, which we are de-identifying and sharing with
other researchers.

This data has already been used by Neuroguide to improve the Network Injury Index.

Autism

Gray Matters has commenced a ground-breaking study combining audio entrainment with neurofeedback to target specific brain networks in autistic children.

Preliminary studies show great promise. A new round of study participants will be enrolled soon.

QEEG-Guided Neurofeedback: New Brain-Based Individualized Evaluation and Treatment for Autism
By James Neubrander, MD, Michael Linden, PhD, Jay Gunkelman, QEEGD, and Cynthia Kerson, PhD

ABSTRACT
QEEG-guided neurofeedback is based on normalizing dysregulated brain regions that relate to specific clinical presentation. With ASD, this means that the approach is specific to each individual’s QEEG subtype patterns and presentation. The goal of neurofeedback with ASD is to correct amplitude abnormalities and balance brain functioning, while coherence neurofeedback aims to improve the connectivity and plasticity between brain regions. This tailored approach has implications that should not be underestimated. . . . Clinicians, including the authors, have had amazing results with ASD, including significant speech and communication improvements, calmer and less aggressive behavior, increased attention, better eye contact, and improved socialization. Many of our patients have been able to reduce or eliminate their medications after completion of QEEG-guided neurofeedback.

Functional Imaging based on swLORETA and phase synchronization
Ernesto Palmero Soler

ABSTRACT
The tomographic properties of swLORETA and sLORETA were compared using both simulated and real data. In the simulation studies, the reconstruction of single and multiple current dipoles was simulated varying their position and orientation across the source space and taking into account the presence of noise. The real data was obtained from healthy subjects who performed a classical spatial attention experiment. The tests performed demonstrated that the resulting algorithm is not only efficient but also accurate as demonstrated by the analysis of a spatial attention experiment.

swLORETA: a novel approach to robust source localization and synchronization tomography
Ernesto Palmero-Soler, Kevin Dolan, Volker Hadamschek, and Peter A Tass

ABSTRACT
Standardized low-resolution brain electromagnetic tomography (sLORETA) is a widely used technique for source localization. However, this technique still has some limitations, especially under realistic noisy conditions and in the case of deep sources. To overcome these problems, we present here swLORETA, an improved version of sLORETA, obtained by incorporating a singular value decomposition-based lead field weighting. We show that the precision of the source localization can further be improved by a tomographic phase synchronization analysis based on swLORETA. The phase synchronization analysis turns out to be superior to a standard linear coherence analysis, since the latter cannot distinguish between real phase locking and signal mixing.

Efficacy of Neurofeedback Treatment in ADHD: The Effects on Inattention, Impulsivity and Hyperactivity
by Arns M, de Ridder S, Strehl U, Breteler M and Coenen A
Journal of Clinical EEG & Neuroscience, July, 2009

ABSTRACT
Since the first reports of neurofeedback treatment in Attention Deficit Hyperactivity Disorder (ADHD) in 1976, many studies have investigated the effects of neurofeedback on different symptoms of ADHD such as inattention, impulsivity and hyperactivity. This technique is also used by many practitioners, but the question as to the evidence-based level of this treatment is still unclear. In this study selected research on neurofeedback treatment for ADHD was collected and a meta-analysis was performed.

Place of EEG Biofeedback for ADHD
by Hirshberg LM
Expert Review Neurotherapeutics, 7(4), 315-319

ABSTRACT
Although methodological weaknesses limited early research into electroencephalograpic (EEG) biofeedback (EBF) for treatment of attention-deficit/hyperacticity disorder (ADHD), recent stronger randomized controlled trials have provided substantial, but not yet conclusive, empirical support. Additional support is found in research on functional magnetic resonance imaging (fMRI) feedback and brain-computer interface (BCI) models which involve feedback-guided learning to achieve control over neural activation.

Electroencephalographic Biofeedback in the Treatment of Attention-Deficit/Hyperactivity Disorder
by Monastra VJ, Lynn S, Linden M, Lubar JF, Gruzelier J, LaVaque TJ

ABSTRACT
Historically, pharmacological treatments for attention-deficit/hyperactivity disorder (ADHD) have been considered to be the only type of interventions effective for reducing the core symptoms of this condition. However, during the past three decades, a series of case and controlled group studies examining the effects of EEG biofeedback have reported improved attention and behavioral control, increased cortical activation on quantitative electroencephalographic examination, and gains on tests of intelligence and academic achievement in response to this type of treatment.

Electroencephalographic Biofeedback (Neurotherapy) as a Treatment for Attention Deficit Hyperactivity Disorder: Rationale and Empirical Foundation
by Monastra VJ

ABSTRACT
During the past three decades, electroencephalographic (EEG) biofeedback has emerged as a nonpharmacologic treatment for attention-deficit/hyperactivity disorder (ADHD). This intervention was derived from operant conditioning studies that demonstrated capacity for neurophysiologic training in humans and other mammals and targets atypical patterns of cortical activation that have been identified consistently in neuroimaging and quantitative EEG studies of patients diagnosed with ADHD.

Treatment of Attention Deficit Hyperactivity Disorder with Neurotherapy
by Nash JK

ABSTRACT 
Significant public health concerns exist regarding our current level of success in treating ADHD. Medication management is very helpful in 60-70% of patients. Side effects, lack of compliance and the fact that stimulant medications cannot be given late in the day limit the benefits largely to school hours.

EEG Biofeedback in the Treatment of Attention Deficit Hyperactivity Disorder
by Friel PN
Alternative Medicine Review, Volume 12, #2, June, 2007, pp146-151

ABSTRACT
Electroencephalogram (EEG) biofeedback, also known as neurofeedback, is a promising alternative treatment for patients with attention deficit/hyperactivity disorder (AD/HD). EEG biofeedback therapy rewards scalp EEG frequencies that are associated with relaxed attention, and suppresses frequencies associated with under- or over-arousal.

I highly recommend Gray Matters as an alternative to traditional treatment for ADHD and Anxiety. The staff are incredibly kind, patient and empathetic. After receiving neurofeedback treatments, we have seen a dramatic reduction in both ADHD and Anxiety symptoms in my son. We found Gray Matters after trying all the traditional treatments with limited success. Neurofeedback has offers us the best result we could have asked for! Thank you Anthony and Alisa!

True miracle work is done here. Anthony has not only helped me take on a new approach to mental and physical health, but has helped me in more ways than any person or medical team ever has. I have tried numerous medications, seen 5 Neurologists, naturopaths, acupuncture, chiropractors, you name it. Gray Matters gave me a fundamental piece of information, that being WHY I lived with chronic pain, depression, Anxiety, and ADHD. I have had about 20 sessions (and continuing) and have had significant relief from migraines, about 70% less! Gray Matters has helped me in more ways than I could possibly describe. I highly recommend this group of wonderful people. After MANY years of searching for relief, I feel I have found it in neurofeedback. Thank you Anthony & everyone else that has helped me as a young female in college to live a life without pain and overwhelming anxiety.

I am very impressed with Anthony Silver's professionalism, efficiency and empathy. My young son has been receiving therapy here and we have seen overall improvements in speech, motor skills, and anxiety. Anthony Silver created an individualized plan based off of an extremely thorough evaluation. His staff are kind and patient, especially Alisa. We are relieved to have found Gray Matters, especially after having a very disappointing and unprofessional experience at a different office in Ridgefield.

I owe a debt of gratitude to Anthony Silver and the dedicated team at Gray Matters. As someone who has struggled with chronic illness, I have sought out many traditional and alternative treatments to alleviate mood symptoms and brain fog. Neurofeedback therapy has been among the most effective. My time at Gray Matters has been a transformative experience and one of the most essential steps on my journey to full recovery. Over the last few months, I’ve seen a meaningful reduction in catastrophic thinking and an increase in mental acuity. Neurofeedback requires persistence and patience. You will begin to notice changes after 10-15 sessions. QEEG Brain Mapping allows you to precisely target your areas of concern. If you stick with the protocol, the rewards are noticeable and lasting. I highly encourage you to contact them.

When I came to gray matters I was suffering from chronic migraines, anxiety, and debilitating fibromyalgia flare ups. Upon analyzing the images of my brain patterns, it was clear I was in constant fight or flight. The first change I noticed was that I was not having to call my doctor to refill my migraine meds early anymore. Over time they were happening less and less frequently and their severity was drastically decreasing as well. I also found that my nervous system was gaining equilibrium and I was not rapidly swinging from bouts of adrenaline and hyperarousal to fatigue and exhaustion. I began sleeping better and feeling clearer cognitively. The true test of the therapy, however, and what truly compels me to write this testimonial is what it has done for fibromyalgia pain. I have flare ups so bad it feels like three different people are hitting me with a baseball bat relentlessly while my muscles are literally on fire. It is mind blowing pain. After searching high and low for a decade for relief and trying out every single alternative and mainstream treatment known to man, I have found neurofeedback to be the only thing to end a flare up. The therapy also has decreased the frequency of flare ups altogether. Anyone who knows the hell of fibromyalgia can attest that relief is a god send and Gray Matters is like an angel to me in this regard. It has taken time and it is a process but the results are cumulative and real and I am beyond grateful to Anthony and the Gray Matters team.

I highly recommend. Anthony Silver of Gray Matters shares an extraordinary combination of scientific expertise with compassionate care. I came to Gray Matters for help with long term challenges of depression and anxiety. After an initial in-depth meeting and qEEG scan, a clear treatment plan was designed to address my specific condition. After a few neurofeedback sessions, I felt significant shifts and improvement. I am very thankful to Anthony and Emma, and look forward to continued growth and wellness.

My 10 year old daughter has been coming for neurofeedback for a little over 2 months. Prior to coming to Gray Matters-she had 60 sessions of neurofeedback with a different practitioner in a different office. Our sessions at Gray Matters are longer and we are doing them more often (3x/week instead of 2x/week). It would be impossible for me to overstate the effect it has had on my daughter and her ability to focus (she was diagnosed with ADHD & dyslexia) her self esteem, self confidence & positive feeling about school and, well, everything! At the risk of sounding overly dramatic-in this short period of time her life has transformed! She works with a math & reading tutor so that is helping too-but without the ability to focus it was extremely frustrating. Focus is the key. I am full with gratitude for having found Anthony & Lauren & can't speak highly enough of our entire experience. They are in the business of providing no less than-hope for the future. (in case you're wondering-I am not related in any way to Anthony and received no gifts or monetary incentive to write this review-it's the real thing!!!)
