If a great deal of what is presented in the four part series on Embodied Cognition sounds familiar, it may be because (as a good friend reminded me) it is mindful of what Alain Berthoz covered in his masterful book The Brain’s Sense of Movement. I went back to the book last night, which came out in 2000 and I haven’t looked at for too long, and was reminded of how profound an influence it was. I had colored tabs, multi-colored highlightings, and sticky-notes all over the book. Of course this made a mess of my Kindle (sorry, Sue – bad joke). Berthoz was influenced by the philosopher Merlau-Ponty who he quotes early in the book as saying that Vision is the Brain’s Way of Touching. Berthoz represents a French school of thought with great relevance to our work, including Stanislas Dehaene and Zoi Kapoula
Reading Berthoz had significant impact on the information that Bob Sanet and I integrated into our chapter on Spatial Vision in the book on Vision Rehabilitation by Suter and Harvey. Aside from using the Merlau-Ponty quote as our guiding light, we took a key diagram (with permission) from The Brain’s Sense of Movement as an important construct for the schematic complexity of something as ostensibly simple as where the brain is directing the eyes to look.
You can get a flavor of Berthoz’s thinking and charm by watching the video below, in which one of my favorite quotes is his line:
“Life has found simplifications which are not so simple”.
Most importantly, if you don’t have your own copy yet, get a hold of Berthoz’s book even if you have to spend a hundred bucks for a paperback reprint though B & N. The implications are all there, from mirror neurons to autism to embodied cognition and even a page or two about rheumatology and ophthalmology, with wide-ranging implications from visual development to robotics. You’ll probably find yourself stopping at least one time per page, putting the book down and muttering under your breath or aloud … wow. To whet your appetite, here is its table of contents:

Dr. Press – I am an occupational therapist in Atlanta and have been following your blog for quite some time. I am very passionate about the visual system and would like to discuss a few things with you if possible. I could not locate an email address to email you. If you are able, please email me at the email below so I can follow-up. Thank-you for your time. Janine
