Spiking tended to occur on the depolarizing crest of such oscillations with depolarization and, thus, in a similar gamma range of frequencies. Calcium responses were evoked in isolated cells by depolarizing voltage steps and monitored by conventional imaging techniques. Depolarizing current injection could identify two functional classes: amacrine cells that fired a single action potential versus those cells that fired repetitively. Cells in which either prazosin blocks the putative depolarization irreversibly or clonidine has little effect are grouped as depolarizing cells. In these cells, full field and spots of medium diameter (1 mm) elicited depolarizing photoresponses. Moreover, depolarizing responses were evident only up to day 16, not thereafter. Drugs were applied approximately 1 min prior to and during the depolarizing steps. Electrical resonance and calcium influx in the synaptic terminal of depolarizing bipolar cells from the goldfish retina. Despite the "redtransient" character of the cell, the maximum depolarizing and hyperpolarizing potential levels remained unchanged during background illuminations. Under our experimental conditions, we recorded a transient inward or depolarizing current at light stimulus onset. The spatial proper ties of the depolarizing responses clearly differ from those of hyperpolarizing ones. Therefore, the effective size of the receptive field is expected to differ for hyperpolarizing and depolarizing photoresponses. This issue was raised because the unitary conductance was apparently quite small - during depolarizing pulses current developed smoothly without discernible single channel events. Properties of the depolarizing synaptic potential evoked by peripheral illumination in cones of the turtle retina. In this experiment, the length constants that were calculated for the depolarizing and hyperpolarizing photoresponses were 201 mm and 510 mm, respectively. Hyperpolarizing responses are denoted by circles and depolarizing ones by crosses. This irreversibly permeabilizes the membrane to cations, depolarizing the cell to "0" membrane potential. |
