Evidence for developmental
role of 5-HT
 5-HT mediates lifelong effects of altered
   maternal care (M. Meaney)
 5-HT depletion or excess during postnatal period:
   disrupted barrel and visual cortices
   reduced hippocampal dendritic spine density
     (J. Haring)
   disrupted calretinin-IR neuron morphology
     (J.-P. Hornung)
