AVL
The Mind of a Worm

Member: AVL.

AVL is a motoneuron/interneuron with its cell body situated in the ventral ganglion. An anteriorly directed process runs in the mid-line on the dorsal surface of the neuropile of the ventral ganglion. It enters the ring on the left and makes a complete circuit running near the outside surface and the anterior face. It then re-enters the neuropile of the ventral ganglion and runs posteriorly down the length of the ventral cord running in the ventral regions of the process bundle. AVL has few synaptic connections in the nerve ring. In the ventral cord the synapses are rather small and are onto muscles (a), SAB (b) and VD12. Synapses are received from DVB and PVP (*e). There is a gap junction to PVM (d), DVB and several rather marginal gap junctions to DVC. Magnifications: (a) 25500, (b-d) x 17000.
