Spontaneous membrane fluctuation in catfish type-N cells.
Type-N (sustained) amacrine cells in catfish retina produce spontaneous membrane fluctuation of about 35 Hz. Fluctuations were seen either in dark or with a steady illumination. As all the distal cells and type-C (transient) amacrine cell did not produce any spontaneous fluctuation, type-N cells were the source of the oscillatory potentials.
