Response of stellate cells to parallel fiber stimulation. Cell-attached patch recordings (A) and whole-cell current-clamp recordings (B) from stellate cells in response to one (left) or five (right) pulses at 100 Hz using low- (i) or high- (ii) intensity stimulation. The high and low stimulus intensities differed by a factor of 2.5. Beneath each example in A andB is a raster plot showing spike timing for five consecutive trials. Below each raster plot is a markerindicating the time of stimulation. In B andC, the horizontal markers correspond to −65 and 0 mV. In C, the responses to five pulses at 100 Hz are replotted on an expanded time scale to better show the initial response to low- (C, left, corresponding to Bi, right) and high- (C, right, corresponding toBii, right) intensity stimulation. Recordings in A and B are from different cells, and traces are single trial examples.
