Neuroanatomy of Prefrontal and Temporal Cortex
My laboratory involved in an analysis of the anatomical and functional organization of the limbic forebrain, and its relation to neurological and psychiatric diseases. The research has focused on the olfactory system, amygdala, related parts of the thalamus and basal ganglia, and, most recently, the prefrontal and temporal cortex. Together these structures constitute a complex, interconnected system that is not directly involved in sensory function, but is implicated functions such in emotional behavior and related modulation of visceral function, reward assessment and prediction, and the ability to make effective choices. The system is involved in disorders such as Alzheimer's disease, epilepsy and clinical depression.

Current studies include experiments in which multiple axonal tracers are injected under physiological guidance into the basal forebrain, medial thalamus, or prefrontal and temporal cortex of monkeys to demonstrate axonal connections. These are correlated with patterns of histological and immunohistochemical staining for neurotransmitters or other markers. The data can, and has been used as a base for interpreting functional patterns in mood disorders, demonstrated with neural activity imaging methods.

Brain tissue from subjects with mood disorders is also being examined histologically to identify cellular changes.  Earlier studies have indicated that there is a ive decrease in glia, especially oligodendrocytes, in major depressive disorder and bipolar disorder.  These results appear to correlate with structural imaging data that have demonstrated differences in white matter volume in subjects with mood disorders.
