Amplification of perforant-path EPSPs in CA3 pyramidal cells by LVA calcium and sodium channels.

abstract：:We propose that the descending command from area 4 that is responsible, in part, for the change in limb trajectory required to step over an obstacle in one's path also plays a role in triggering the anticipatory postural modifications that accompany this movement. To test this hypothesis, we recorded the discharge cha...
