Waveforms of auditory response in V1.

<p>(A) Averaged auditory responses in the ROI of V1. (a1) Each thin trace is the response in V1 in a single animal; the trace is the average of 96 trials. The thick trace is the average of all thin traces obtained from 16 animals. (a2) From the data shown in (a1), a <i>t</i>-score was calculated at each sampling point, and all calculated <i>t</i>-scores are presented as a time series. The shaded region shows the time window when responses are significantly negative (<i>p</i><0.05; Student's <i>t</i>-test). The horizontal bar shows timing and duration of the auditory stimulus. (B) The auditory response at the epicenter of negative signals in V1. (b1) Each thin trace is the response in V1 in a single animal; the trace is the average of 96 trials. The thick trace is the average of all thin traces obtained from the same 16 animals as in (a1). (b2) From the data shown in (b1), a <i>t</i>-score was calculated at each sampling point, and all calculated <i>t</i>-scores are presented as a time series. Other conventions follow (a2).
