Welcome to the blog. The content highlights:

  • Research which I think is in some way connects to the diverse applications of Interactive Metronome. Initially there will be an emphasis on concussion and learning disabilities.

  • Research re nutrition, breathing, sleep ,or physical exercise which I think could have a complementary impact on an Interactive Metronome intervention.

  • The implications of research which indicates a massive increase in the number of children being diagnosed as being on the autism/aspergers spectrum, and or pervasive developmental delay. There is contextual research which shows interesting correlational data, especially to this increase in autism. It’s often ignored or given very little space in the main stream media. I will start listing this correlational research.

Readers comments will be added. Please use the contact page if you think you have some relevant information to share re any of the research posted in the blog.

The scientific case for water fluoridation is such a contentious issue in NZ our parliament recently decided local councils were not sufficiently resourced enough to handle the issue. Instead the local Health Boards, staffed by medically trained personnel were seen as a sensible alternative. A person with a professionally trained mind is usually capable of staying with logical deduction, despite various twists and turns. And well they need to. The problem is very often people with trained minds ‘forget’ they remain susceptible to the human capacity for being tranced. This ‘forgetting’ is itself, a tranced state of mind. A professional person in this state of mind can actually be quite dangerous. They have a  predisposition to staying tranced long after many less educated people have woken up. Doctors advocating for fluoridation of water supplies are looking more like an example of exactly this phenomenon … According to the Cochrane review below the best we can expect is 35% less caries in children. However the studies supporting this are pre 1975, pre fluoride toothpaste, and poorly designed. “Our confidence in the size of the effect estimates is limited by the observational nature of the study designs, the high risk of bias within the studies and, importantly, the applicability of the evidence to current lifestyles”

Water fluoridation for the prevention of dental caries

  • Review
  • Intervention



Dental caries is a major public health problem in most industrialised countries, affecting 60% to 90% of school children. Community water fluoridation was initiated in the USA in 1945 and is currently practised in about 25 countries around the world; health authorities consider it to be a key strategy for preventing dental caries. Given the continued interest in this topic from health professionals, policy makers and the public, it is important to update and maintain a systematic review that reflects contemporary read the Cochrane review click this link

Yet another piece research that offers parallel support to the IM approach to improving ASD symptoms A research team has identified an abnormally high synchrony between the sensory cortices involved in perception and subcortical regions relaying information from the sensory organs to the cortex for those with ASD. Here’s the link to a summary of the paper. Interactive Metronome provides the opportunity to pay close conscious attention to repeated opportunities for more accurate synchronisation  of multiple sensory data. This provides optimal opportunity for beneficial neuroplastic change. See the beginning few minutes of this video for an more in-depth understanding of the previous sentence.

Atypical Brain Connectivity Associated with Autism Spectrum Disorder

Autism spectrum disorder (ASD) in adolescents appears to be associated with atypical connectivity in the brain involving the systems that help people infer what others are thinking and understand the meaning of others’ actions and emotions. Here’s a link to a summary of the paper.

There’s good reason to believe that Interactive Metronome strengthens white matter neural connections between various parts of the brain.  Further, numerous Interactive Metronome case studies report that IM training helps to reduce symptoms of ASD. The challenge for those promoting IM is that as yet a definitive explanation as to why it works is not yet available. However there is research coming from numerous independent sources that point towards a validation of the IM approach to a range of learning disabilities and other conditions, including ASD. The beauty of the IM approach is that it is elegantly simple, performance results are objectively observed, and there haven’t been any reports of harm from trying it out.

Fast Food Consumption Linked to Lower Test Score Gains in 8th Graders

The amount of fast food children eat may be linked to how well they do in school, a new US-wide study suggests.

This study included about 11,740 students. They were tested in reading/literacy, mathematics and science in both fifth and eighth grades. They also completed a food consumption questionnaire in fifth grade.

Researchers found that the more frequently children reported eating fast food in fifth grade, the lower their growth in reading, math, and science test scores by the time they reached eighth grade.

Students who ate the most fast food had test score gains that were up to about 20 percent lower than those who didn’t eat any fast food, said Kelly Purtell, lead author of the study and assistant professor of human sciences at The Ohio State University.

A review of magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) findings, in mild traumatic brain injury

I’m yet to view the results of the latest working party re head injury by ACC, released very recently. I’ll be interested to see if the issue in this article is adequately covered.

In essence a DT image shows the white matter neurons that make up the neural connections within and between the various layers and lobes of the brain. It is the shearing of these neural connections that is strongly associated with Post Concussion Syndrome. The minute aspects of this damage do not show up on an MRI.

From a personal contact within the industry supplying scanner equipment internationally, I’m informed that there is probably only one DTI scanner in NZ.

So here’s the “one big damn puzzler”: With a national organisation, namely ACC, having to deal with literally thousands of New Zealanders every year who complain of Post Concussion Syndrome, why don’t we have DTI scanners available throughout the country so we can get some objective data on evidence that either supports or strongly questions the grounds for PCS?

My source tells me there are approximately forty to fifty 1.5 Tesla powered MRI scanners in NZ. As for 3 Tesla powered MRIs, there’s about 14 of them. I’m told DTI software, and a magnetic cradle for the head (where there isn’t already one) is all that’s needed to enable an MRI scanner to produce DTI images. That could cost $200, 000 for each machine. Sounds like big money, until we recall that ACC spend upwards of $60 Million a year on head injuries. Oh, and DTI scanning has been around for over a decade. Hmmm … there’s something about this situation that’s just not making apparent sense.

There’s a lot of truth in the advice that if you want to know why what’s going on, is going on, follow the money.  So that raises two questions:

Who or what organisations are the beneficiaries of the money-flow pattern for the status quo re the identification or otherwise of PCS in NZ?
How might that pattern change if the wide-spread use of DTI scans were available to help bring a more conclusive diagnosis of PCS?

I don’t know the answers to those questions. I’d be interested in them, and I’d guessing there would be quite a few others interested too.

Sound Training Rewires Dyslexic Children’s Brains for Reading

Here’s a some research from 2007 that supports a basic tenant of Interactive Metronome -improving sound processing can lead to an improvement in reading


Brain imaging adds further support to the idea that at least some children with dyslexia have trouble processing sound, rather than a visual problem. The study also shows that computer-based sound training exercises can not only improve reading but literally rewire the brain. The findings may help clinicians detect and remediate dyslexia even before children begin learning to read. Read a fuller report here

Growth of Autism Spectrum Prevalence 

I get nervous when I hear relatively young professionally medically trained people expressing strong opinions that are in agreement with any range of medically orthodox opinions. Mainly because I’ve been on the planet long enough now, to observe two patterns. One is that orthodox opinion on so many medical topics can change. Actually that’s not a problem if it’s change because of better science. The more un-nerving setting is when orthodox opinions are espoused, despite the accumulation of evidence that at least gives pause for thought.

Here’s a very recent article from the Journal of Public Health & Epidemiology that should be an interesting read especially for any medically trained readers, who are unquestioningly pro vaccination.

The aim of this study was to investigate a previously overlooked, universally introduced environmental factor, fetal and retroviral contaminants in childhood vaccines, absent prior to change points (CPs) in autistic disorder (AD) prevalence with subsequent dose-effect evidence and known pathologic mechanisms of action. Worldwide population based cohort study was used for the design of this study. The United States, Western Australia, United Kingdom and Denmark settings were used. All live born infants who later developed autistic disorder delivered after 1 January 1970, whose redacted vaccination and autistic disorder diagnosis information is publicly available in databases maintained by the US Federal Government, Western Australia, UK, and Denmark. The live births, grouped by father’s age, were from the US and Australia. The children vaccinated with MMRII, Varicella and Hepatitis A vaccines varied from 19 to 35 months of age at the time of vaccination. Autistic disorder birth year change points were identified as 1980.9, 1988.4 and 1996 for the US, 1987 for UK, 1990.4 for Western Australia, and 1987.5 for Denmark. Change points in these countries corresponded to introduction of or increased doses of human fetal cell line-manufactured vaccines, while no relationship was found between paternal age or Diagnostic and Statistical Manual (DSM) revisions and autistic disorder diagnosis. Further, linear regression revealed that Varicella and Hepatitis A immunization coverage was significantly correlated to autistic disorder cases. R software was used to calculate change points. Autistic disorder change points years are coincident with introduction of vaccines manufactured using human fetal cell lines, containing fetal and retroviral contaminants, into childhood vaccine regimens. This pattern was repeated in the US, UK, Western Australia and Denmark. Thus, rising autistic disorder prevalence is directly related to vaccines manufactured utilizing human fetal cells. Increased paternal age and DSM revisions were not related to rising autistic disorder prevalence.

Males and females with autism show an extreme of the typical male mind -Cambridge University

The largest ever psychological study of sex differences in adults with autism has found that both males and females with autism on average show an extreme of the typical male mind, where systemising (the drive to look for underlying rules in a system) is stronger than empathising (the ability to recognize the thoughts and feelings of others and to respond to these with appropriate emotions). Read a summary of the study here. Read the full paper here.
