The effect of richness of the environment on behavioral function was investigated in C57B6 mice. Animals were raised in either enriched (group-housed in large clear plexiglas cages with stimulating objects) or restricted (group housed in opaque white plastic cages with no stimulating objects) environmental conditions and their spatial learning and visual(More)
The regional specificity and functional significance of learning-dependent synaptogenesis within physiologically defined regions of the adult motor cortex are described. In comparison to rats in a motor activity control group, rats trained on a skilled reaching task exhibited an areal expansion of wrist and digit movement representations within the motor(More)
