I normal aging, Alzheimer's disease and AIDS related dementia. Recent work includes fMRI studies of prefrontal and medial temporal lobe interactions in picture and word encoding, examining the role of prefrontal and medial temporal love contributions to working memory for spatial, non-spatial, and complex visual stimuli, and studies combining cognitive, physiological and morphometric methods to examine changes associated with aging. Imaging is carried out at the Massachusetts General Hospital-NMR Center. Students and postdoctoral fellows are provided with training in cognitive neuroscience, neuroanatomy, block design and event-related fMRI, cortical inflation and flattening techniques, and cortical parcellation techniques. In 1999, installation of MEG facilities at the MGH-NMR Center will further enhance available research opportunities.
Specific emphasis is effects of attention on motion processing.
