URMC Neurology Research
Scope of Research: Basic and Clinical Research on Neuronal and Perceptual Mechanisms of Cognitive Function; Experimental Therapeutics of Age-Related Neurodegenerative Disorders; Neuropsychological and Biomarker Studies in Normal Aging and Age-Related Neurodegenerative Disease
Our goals include pursuing: 1) Basic science research on the neuronal mechanisms of cortical information processing and clinical research on perceptual and cognitive impairments in dementing illnesses, especially Alzheimer’s disease (AD). 2) Neuropsychological and clinical experimental therapeutic research on normal aging, Alzheimer’s disease and other neurodegenerative disorders including Parkinson disease, Huntington disease, Multiple System Atrophy and rarer dementing illnesses.
Our current activities focus on the following areas:
•
Clinical diagnosis and sub-specialty care of dementia patients
•
Patient oriented teaching in the medical school and post-graduate
curriculum
•
Psychophysical analysis of spatial disorientation in aging and
AD
•
Behavioral assessment of navigational disorders in aging and AD
•
Single neuron neurophysiology of navigational mechanisms in behaving
monkeys
•
Human neurophysiological studies of visuospatial processing in
aging and AD
•
Single neuron neurophysiology of visual motion processing in behaving
monkeys
•
Functional imaging studies of white matter changes in aging and
AD
•
Perceptual studies of attentional disorders in aging and AD
•
Perceptual studies of reading impairments in aging and AD
• Experimental therapeutics studies in a variety of neurodegenerative disorders including Alzheimer Parkinson, Lewy Body, Huntington, Multiple System Atrophy, Batten, and others.
• Longitudinal neuropsychological and biomarker studies in normal aging, mild cognitive impairment and age-related dementias
