Additional interests concern the effects of hypertension or malnutrition on brain neurochemistry.
A third major research interest is the neurobiology of autism affecting cerebellar and limbic circuitry and neurotransmitter systems. In the rat brain we are exploring the effects of prenatal protein deprivation on postnatal neurogenesis, with emphasis of the effect on the cell cycle and on the generation of granule cells in the hippocampus. In the rhesus monkey we are looking into the effect of age on the glial cell responses in the white and grey matter. In the human brain we are investigating the structural and chemical defects in infantile autism. The goal of my present work is to determine what contributions the major afferent pathways, through either the tectum or LGN, to extrastriate cortex make to the execution of visually-guided behavior.
