## Abstract

Human visual event-related potentials (ERPs) and the electroencephalogram (EEG) measure a variety of
different cognitive operations during visual processing. Visual ERPs and EEG are vital tools in diagnosing and
studying neurological and psychopathological disorders, in addition to revealing how the health brain turns
visual inputs into appropriate responses. However, it is not possible to definitively determine what brain areas
generate specific ERP components and EEG oscillations related to deploying visual attention, visual working
memory storage, and monitoring task performance. The renewal of this project will support our work localizing
the sources of ERP components and oscillatory signatures elicited during the performance of visual tasks
using both humans and nonhuman primates. In the latter we will record noninvasive ERPs and EEG
simultaneously with intracranial recordings of local field potentials. These recordings will be used to perform
forward modeling of the neural generators from inside the head. Preliminary evidence from monkeys and
humans performing identical visual tasks demonstrates homology between human and macaque ERP
components and the modulation of specific frequency bands in the EEG providing indices of the deployment of
visual attention, the storage of visual information in visual working memory, and performance monitoring. By
concurrently studying humans and monkeys this project will allow clinicians and health researchers to use the
visually and response evoked EEG activity and ERP components recorded noninvasively from humans to
access whether specific brain regions are functioning properly and also to develop animal models of specific
disorders.
