Review Notes on Distributed and Overlapping Representations of Faces and Objects in Ventral Temporal Cortex

Overview

By this point of time, everyone agrees that there is a distinct pattern of response for each stimulus category with the object vision pathway in the human brain. Point of debate is the nature of distinctiveness.

As per the paper,

Distinctiveness of the response to a given category was not due simply to the modular regions that responded maximally to that category. Based on the experimental fact from the paper that,

Review Summarization

Above fact suggests that the “modular” areas are making a differentially important contribution. So concluding that it is a little of both: specialized areas but also widely distributed representations.
