The neuroscience prosopagnosia

By Razib Khan | November 30, 2008 10:23 pm

A few years ago I blogged about prosopagnosia, “face blindness.” Nature Neuroscience now has a new paper finding some correlates with brain architecture, Reduced structural connectivity in ventral visual cortex in congenital prosopagnosia:

Using diffusion tensor imaging and tractography, we found that a disruption in structural connectivity in ventral occipito-temporal cortex may be the neurobiological basis for the lifelong impairment in face recognition that is experienced by individuals who suffer from congenital prosopagnosia. Our findings suggest that white-matter fibers in ventral occipito-temporal cortex support the integrated function of a distributed cortical network that subserves normal face processing.
