Neural mechanisms for predictive head movement strategies during sequential gaze shifts.

abstract：:1. Ca(2+)-dependent K+ currents were studied in large pyramidal neurons (Betz cells) from layer V of cat sensorimotor cortex by use of an in vitro brain slice and single microelectrode voltage clamp. The Ca(2+)-dependent outward current was taken as the difference current obtained before and after blockade of Ca2+ inf...
