Course Description / Policies

A general survey of the structure and function of the cerebral cortex. Topics include cortical anatomy, functional localization, and newer computational approaches to understanding cortical processing operations. Motor cortex, sensory cortex (visual, auditory, and somatosensory cortex), association cortex, and limbic cortex. Emphasis is on using animal models to understand human cortical function and includes correlations between animal studies and human neuropsychological and functional imaging literature.

Students will present papers during the class (one per class.) In addition, two students per paper will be assigned as "discussants". Discussants will prepare questions for the paper presenter, to help the group get to the core issues of each paper.
