Some central neurons in the crayfish have autofluorescent cell bodies. The yellow fluorescence of cell bodies was induced in the whole-mount preparation by using blue-violet light from a high-pressure mercury lamp. From the first to the fifth abdominal ganglion, a pair of cell bodies fluoresced in e
The intrinsic "spontaneous" activity of a nerve center can vary in number of active units and in unit frequencies. An analysis of a synchronous nerve center, the Limulus heart ganglion, has recently been made (Prosser, '43). A partial analysis of an asynchronous center, the abdominal ganglia of the
