What insights can fMRI offer into the structure and function of mid-tier visual areas?
... V1-encoded visual features are represented in V1. This very integrative view of V1 as a node in a distributed network makes particular sense when one considers that, perhaps, 10% of the inputs to V1 come from “below” V1 (i.e., subcortical sources) (Logothetis, 2008), while the vast majority come fro ...
