Multiple high-threshold calcium currents in acutely isolated rat amygdaloid pyramidal cells

J Neurophysiol. 1994 Jan;71(1):433-6. doi: 10.1152/jn.1994.71.1.433.

Abstract

1. High-threshold Ca2+ currents were studied in large pyramidal cells acutely dissociated from the rat amygdaloid complex. L-, N-, and P-type currents were present in about equal proportions in these cells and accounted for most of the whole-cell current.
