Effects of 5-HT on thalamocortical synaptic transmission in the developing rat.

abstract：:Children do not typically appear to move with the same skill and dexterity as adults, although they can still improve their motor performance in specific tasks with practice. One possible explanation is that their motor performance is limited by an inherently higher level of movement variability, but that their motor ...
