"Two issues about cortex: where is V2 and is cortical plasticity cortical?"
In this first talk of the New Year, I will consider two specific aspects of neocortical organization and function that are under contention. First, what happened to the second visual area, V2 , of rats and mice? Current proposals do not include this classical visual area, and present a conflicting interpretation of the organization of visual cortex.
This impacts on the use of these rodents as models of visual processing. I will argue that they do have a V2. The second issue is that it has been common to attribute functional changes in cortical sensory areas after sensory loss to cortical plasticity. I will argue that they are often the result of subcortical changes. Thus, fMRI studies of cortical reorganization in humans should consider this possibility.
