Regional Cerebral Blood Flow Studies of Object Perception, Identification, Localization, and Memory
National Institute of Mental Health (NIMH)
Summary
The purpose of this study is to use brain imaging technology to measure changes in blood flow to areas in the brain as individuals perform intellectual tasks. This study will use functional magnetic resonance imaging (fMRI) to examine blood flow to areas of the brain as participants engage in tasks associated with visual perception, visual recognition, and memory....
Description
Objective: Our goal is to study the functional organization of the intact human brain by combining cognitive tasks and neuroimaging. Functional magnetic resonance imaging (fMRI), magnetoencephalography (MEG) and electroencephalography (EEG) will be used to measure brain activity in healthy human subjects engaged in performing cognitive tasks. These tasks will address specific questions concerning the neural systems that mediate perception, attention, memory, decision-making, emotion, plasticity and social interactions. fMRI and MEG, respectively, will be employed to investigate the spatial an…
