Characterization of a calcium current in a vertebrate cholinergic presynaptic nerve terminal.


Calcium currents were recorded from a cholinergic presynaptic nerve terminal in the chick ciliary ganglion using the whole-cell voltage-clamp technique. The presynaptic element of this synapse is in the form of a calyx that envelops the postsynaptic ciliary neuron. A method was developed to isolate the ciliary neuron, expose the calyx, and apply patch-clamp… (More)
