Associated Functions
Reviewer's note

Several visual functions found in BA18 are also observed in BA19; or, more exactly, in several visual functions (e.g., detection of light intensity, feature attention, detection of patterns, etc.) BA18 and BA19 are simultaneously activated, suggesting that they participate in a common brain network. In some other visual functions (e.g., spatial working memory; “where is it?”, that is, stimulus localization) only BA19 is active. It is interesting to emphasize that, BA19 participates in some language related functions, in particular processing phonological properties of written words (fusiform gyrus), confrontation naming (BA18/19/37 plus the inferior frontal gyrus) and sign language (BA37/19).
