  • Chronic (-) deprenyl (0.2 mg/kg, b.wt; for 25 days) treatment induced alterations in the dendritic morphology of prefrontal cortical neurons in adult Bonnett monkeys were evaluated in the present study. The branching points and intersections in apical and basal dendrites were studied up to a distance of 400 and 200 μm, respectively, in Golgi impregnated layer III pyramidal neurons of the prefrontal cortex. Our results revealed a significant (p < 0.001) increase in the number of branching points and intersections in both apical and basal dendrites in (-) deprenyl treated monkeys compared to controls. Such an enriched dendritic arborization in prefrontal cortical neurons may be responsible for the enhancement of cognitive functions in Alzheimer disease patients following (-) deprenyl treatment.
