Effects of stimulation frequency on evoked components.

<p>(<b><i>A</i></b>) Representative responses of one mouse to various stimulus trains (30 stimuli per train) at frequencies between 0.2 and 50 Hz (indicated at left). Each trace shows the mean local field potential (averaged over the last 20 stimuli) recorded near the Purkinje cell layer of the Crus I/II area. In control conditions, the stimuli were delivered every 10±3 s. To facilitate visual comparison, dotted lines have been placed to indicate the locations of the N1, N2, and N3 peaks observed before stimulation. The arrowheads indicate shifts in the peak latencies. (<b><i>B</i></b>) Superimposed traces of mean averaged local field potentials obtained at stimulation frequencies from control to 8 Hz. Traces were aligned with the stable N1 component. Dotted lines indicate the locations of the N1, N2, and N3 peaks observed before stimulation. (<b><i>C</i></b>) Single-trial traces that correspond to the local field potentials in response to the first 10 stimuli (8 Hz) in a train (numbered at left). Single control stimuli responses were recorded just before the train (top) and just after (bottom) the 10^th stimulus (8 Hz).
