Transmitters in Buccal neurons

Each neuron in the buccal system responds to a neuronal transmitter in one way only, irrespective of where the transmitter comes from. This is known as Dale's principle. Most transmitters are released from synaptic connections upon the influx of calcium ions.

Each kind of Buccal interneurons releases a different transmitter,  so that  acheive their co-ordinated effects. This table shows some of the transmitters that have been investigated in my lab, or other UK labs:

Neuron
Transmitter
SO
acetylcholine
N1M
acetylcholine
N2
glutamate
OC
octopamine
CGC
serotonin


Most of the work in my lab has concerned octopamine, and its role as a transmitter and as a modulator. Here is a review I wrote recently:
