Areas of Interest: Event-Related Potentials, brain dysfunction
Current Research:
Dr. Squires' laboratory investigates the sensory and cognitive processes of the human brain using recordings of electrical activity from the scalp (event-related potentials or ERPs) and neuropsychological-assessment techniques. Some of studies currently underway are: ERPs and affective processing, ERP and fMRI in stroke patients with aphasia, and ERP correlates of receptive language in the first and second languages of bilinguals. Often our experiments include comparisons between normal control populations and populations with brain dysfunction. Some of the disorders we have studied in the past include reading disability in children and adults, risk for Alzheimer's disease, sleep disorders, multiple sclerosis, traumatic brain injury, and Lyme Disease. We are part of a proposal for an Autism Center, where our part will be the study of emotion and the brain in collaboration with the laboratories of Drs. Freitas and Leung.
