Abstract
The purpose of this chapter is to consider the actions of depressant drugs on calcium entry into neurons. Since presynaptic calcium entry is an essential link in excitation-secretion coupling of synaptic transmission, a reduction of calcium entry by depressant drugs should produce a reduction in neurotransmitter release and therefore a reduction in synaptic transmission. In this chapter we will review evidence obtained by using intracellular recordings from mouse neurons in primary dissociated cell culture which indicates that barbiturate and opiate drugs reduce presynaptic calcium entry. Evidence will also be presented which suggest that there are substantial differences in the manner in which these two drug classes modify calcium movement.
