Electrotonic coupling and afterdischarges in the Light Green Cells: a comparison with two other cerebral ganglia neurosecretory cell types in the pond snail. Lymnaea stagnalis.
Electrotonic coupling occurs between the growth hormone-producing Light Green Cells on the same but not the opposite side of the brain of Lymnaea. Long duration inhibitory post synaptic potentials occur spontaneously or can be evoked by nerve or connective stimulation. Afterdischarges, lasting for up to 1 min, are evoked by brief stimulation of the median lip nerves. Activity is confined to cells ipsilateral to the nerve being stimulated. The electrical properties of the Light Green Cells are compared with those of the Caudodorsal Cells and Canopy Cells.
