a Polar plots (of the entire trial period) of time of significant CS modulation during learning relative to the time of cue onset (left), symbol onset (middle) and reward onset (right) for each cell for all wP-cells (top) and cP-cells (bottom). Each line on the plot represents time of significant modulation of CS (in ms) relative to the respective event signifying the temporal relationship between delta epoch and CS activity. b Left: SS activity for wP-cells in correct (left) and wrong (right) trials with CS present in the previous trial (abscissa) vs CS absent in the previous trial (ordinate). Right: same as left; but for cP-cells. c Duration of CS waveforms at the beginning (b), during (m), and end (e) of delta epoch for wP-cells (left) and cP-cells (right). Histograms were normalized to the maximum frequency among all epochs. d Probability that a trial (t) during learning would be correct, given there was a CS in the previous trial (t – 1) in cP-cells (left) and wP-cells (right). e Peak CS activity for correct (blue) and wrong (red) trials during learning at the beginning (left), during (middle), or the end (right) of delta epoch for cP-cells (top) and wP-cells (bottom). Data shown as mean ± s.e.m. Source data are provided as a Source Data file.
