COGNITIVE NEUROSCIENCE

Cognitive neuroscience is the study of human mental functions such as remembering, attending, decision making, reading and speaking, problem solving, etc., and the computational processes and neural mechanisms underlying these functions in the human brain. Cognitive neuroscience research at the CSL includes the following topic areas:

Event-related brain potential studies of visual attention

Changes in attentional functions through the adult life span

Eye movements and attention

Genetic polymorphisms associated with visuospatial attention and memory

Event-related potential (at CSL) and functional magnetic resonance imaging (at NIMH) studies of attention and visual motion priming.

The methods used by the cognitive neuroscience research group are diverse. They include perceptual and cognitive tests such as spatial orienting, visual search, motion perception, and spatial memory; event-related potentials of the brain, and eye movements. In addition, functional Magnetic Resonance Imaging (fMRI) studies are carried out in collaboration with researchers at the National Institutes of Mental Health.
