Crustacean Neuromuscular Glutamatergic and GABAergic Channels with Some Comparison to Drosophila Channels
In crustacean muscle glutamate is the excitatory and GABA the inhibitory transmitter. The respective glutamatergic and GABAergic channels have been investigated in on-cell and excised patch-clamp recordings. The glutamatergic channels are compared to such channels in Drosophila larvae which have very similar characteristics. Based on the recordings, reaction schemes for glutamatergic and GABAergic channel types are proposed, and the conditions for generation of a quantal current event are discussed.
