New developmental prosopagnosia research hot off the web

While I was looking at the website of the Journal of Neuroscience I found this interesting and important free access article:

Michael Lohse, Lucia Garrido, Jon Driver, Raymond J. Dolan, Bradley C. Duchaine, and Nicholas Furl Effective Connectivity from Early Visual Cortex to Posterior Occipitotemporal Face Areas Supports Face Selectivity and Predicts Developmental Prosopagnosia. Journal of Neuroscience. 30 March 2016, 36(13): 3821-3828; doi: 10.1523/JNEUROSCI.3621-15.2016

What is face selectivity? I’ll have to do a bit of study on that.

For me the findings of this study are not surprising, even though there are apparently new ideas in this paper about face selectivity and developmental prosopagnosia (DP). As a synaesthete who also appears to be a “super-recognizer” of faces from a family in which precociously high levels of literacy skills are found, I firmly believe that the common thread that runs through synaesthesia, literacy skills and face memory is good to exceptional connectivity inside the brain. My ideas are supported by research that has linked synaesthesia with hyper-connectivity, and has linked dyslexia and DP with problems with connectivity.

There is a tiny little face inside your brain (or at least there should be one)
