Left Brain/Right Brain first came into existence in 2003. Over the years it has changed its basic form a few times but its core content and interest has always been autism and the news, science – and bad science – associated with it.

Left Brain /Right Brain was started by Kevin Leitch. Over the years many people, autistics, parents and professionals have contributed articles.

Left Brain /Right Brain is currently operated by Matt Carey, a parent of an autistic child. Professionally, Mr. Carey is an industrial researcher in computer hardware with over 100 scientific publications in high impact journals and numerous patents. Mr. Carey has also presented a study at IMFAR and published a response reanalyzing autism administrative prevalence data from a previous study. Mr. Carey writes under the nickname “Sullivan”.

      —2012 Current Trends in Autism Conference—
      Hi Michael,
      Thank you so much for mentioning last year’s conference on your site! I just wanted to inform you of this year’s conference. We’ve gone above and beyond to deliver participants the best CTIA Conference yet! We’ll have a special set of lectures discussing adult autism, the conference will be larger and with more guest speakers, and participants will have additional opportunities to interact and become involved in the autism community in New England! Please spread the word!

    Hi Mr. Carey,

    I don’t know if you realize it, but in this post, http://leftbrainrightbrain.co.uk/2012/08/04/the-15-year-fallout-from-one-mans-lie-about-vaccines/ you have used a pseudonym to comment while using your own name to sign the posts.

    While I’m sure it’s not your intention, it does give one the impression that you’ve been engaging in some “astroturfing.”

    Even careful and regular readers of your blog posts may not remark on this, so accustomed to your pseudonym are we. But other autism bloggers have been called on this in the past, and I think its only fair to apply that same standard to LBRB. Perhaps you could be more careful about this in the future?

      thanks for that. I hadn’t thought of that perception. I’ll work on ways to make this more transparent.

        Testing to see if edits to my profile come through in the comments.

        Thanks, Morgan.

        I think this works better.

    @morgan – those other “autism / anti-vaccine” bloggers aren’t worth the electrons their words are printed on. I couldn’t care less about them & I’m sure, based on their relentless against against Mr. Carrey for the sole reason of his lack of support for their anti-vaccine screeds, that Sullivan couldn’t care less either what they think about the way he posts.

    Hi Matt Carey –

    You do a pretty good job of playing straight up the middle — and that is very much appreciated. Hate to see you stray into the rough.

      Thank you, very much. Kev Leitch made this site and made a big impact on changing the direction of online discourse about autism, especially within the parent community.

    I thought you might like to blog about this…

    With 1/88 children currently diagnosed with autism, new ideas for treatment and diagnosis are more important than ever. Three innovators in the field of autism are turning to crowd funding to support their ideas and research. Crowd funding (used heavily by the entertainment industry for years) has only recently begun to be a tool used by researchers.

    British researcher Dr. Tamie Salter (tamie@queinnovations.com) is conducting a crowd funding project to help launch a new product called the KOULE (www.Indiegogo.com/KOULE). KOULE is a robotic ball that has programs that are designed to assist children living with cognitive challenges, such as autism. KOULE has been developed by a team of experts from different fields; including Child development experts and engineers, with promising preliminary results. Dr. Salter has research work in a book available on amazon (http://alturl.com/y9ztg), has been featured in a National Geographic Documentary and is being advised by some of the best technology business leaders.

    Dr. Alisa Woods (awoods@clarkson.edu) is using a technique called mass spectrometry to try to develop an autism diagnostic test. Dr. Woods is analyzing proteins found in blood and saliva of children with autism and comparing them to kids without autism. She has found some promising markers that can indicate possible autism risk. Dr. Woods is not just a researcher; she is also a parent of a child with autism. She has seen the positive effects of early intervention first-hand. Dr. Woods has published a recent article focusing on cholesterol disturbances in psychiatric disorders, including ASD.

    Individuals with autism seem to really enjoy playing video games. This being the case, why not use games to help them learn skills? As both a video game blogger and autism researcher, Dr. Elisabeth Whyte of Penn State is improving current computer-based intervention designs by including video game elements. Adolescence may be particularly important for developing face processing (Scherf, Luna, Minshew, and Behrmann, 2010). Preliminary results indicate that individual cartoon characters called “greebles” improved face recognition behavior for the adolescents with autism after completing the intervention, compared to adolescents with autism who did not play with the characters.

    Hi Matt Carey,

    As a pediatrician, scientist and HMC (P’87) alum, we should consider communicating about mutual common interests.

    Fact check– I’m just reading different web hits re autism and Dr. David Ayoub. Your site’s 2006 article that mentions Dr. Ayoub and “Black Helicopters” stated, “….which is nothing short of miraculous given that fifty years ago (1955 when Ayoub gave this talk) the Kissinger report (1974) hadn’t even been written.” David Ayoub, fyi, hadn’t even been born in 1955. He was a classmate of mine in grade and high school.

    • Sullivan (Matt Carey) July 22, 2013 at 00:11 #

      I didn’t write that article, but let me see if I can understand the issue.

      “He then says that _”these are the social issues we’ve faced for the last fifty years. They’ve come out of this document.”_ which is nothing short of miraculous given that fifty years ago (1955 when Ayoub gave this talk) the Kissinger report (1974) hadn’t even been written. There’s some more of that ‘science prodigy’ genius leaking through again.”

      “this document” per the article is the Kissenger report. Not something by Mr. Ayoub.

      David Ayoub appears to be stating that problems going back as far as 1955 result from a report written by Henry Kissenger in 1974. So, the fact that Mr. Ayoub had not been born isn’t really a concern. The fact that he’s claiming that the Kissenger report had effects 19 years before it was written is, well, a bit of a logical problem.

    I’ve been looking through your site and I think it’s great! My name is Terisa and I work for an on-line agency whose clients are wedding, fashion and sports brands. I am willing to sponsor some content on your (~http://leftbrainrightbrain.co.uk/). The first option would be to pay you to put a link to our client within an existing article of yours or I could write some brand new content for your blog- something that fits your site’s niche- and I could pay you to publish that. I would also like to include a hyperlinked picture from my clients catalogue if possible.
    Alternatively, if you wanted to write an article and post a link within it I could pay you a larger amount.

    Do let me know if this kind of thing interests you.

    Many Thanks,

    Hi Matt,

    I came across your blog and wanted to write, a bit about myself:

    My name is Nicole Caron, and I’m the Social Media Manager at VoiceItt. VoiceItt is developing innovative speech technology that will enable people that suffer from motor, speech, and language disorders to easily communicate using their own voice, by translating the unintelligible pronunciation into understandable speech. The software based solution can run on any mobile or wearable device, allowing the person to communicate freely with anyone anywhere. The video on our Indiegogo campaign explains it.


    We have been promoting our product through various radio stations and podcasts, and I thought this would be a great story for you as it’s both technologically revolutionary and very emotional. If you could write a short post about our product and campaign, it would be wonderful to tell your readers about how millions of lives can be changed!

    Let me know if you have any questions, I will be happy to answer them. I’ve attached some photos and a press release. Looking forward to hearing from you! :)

    Kind Regards,


  15. Sheogorath November 27, 2014 at 02:24 #
