Activity in Buccal neurons

The Buccal neurons are divided into motoneurons, which innervate muscles and interneurons, which are mostly confined to the buccal ganglion. The interneurons are active in turn, with each type of nterneuron only active in one phase of the rhythm. Motoneurons may be active in more than one phase. the picture below shows a simplified diagram, showing which neurons are active in any one phase:

Red cells active
Black cells quiet
Excitatory synapses
Inhibitory synapses

By impaling two neurons with microelectrodes at the same time, we can measure the synaptic connection(s) between them. This is in the next part of this website.
