aFor session-based analysis (Figs. 15,16), recording sessions with >5 simultaneously recorded pyramidal cells were analyzed.
bBehavioral performance, early lick rates, reaction time, and trial number were calculated based on behavioral sessions. In some cases (8 sessions in auditory tasks with 1.2 s delay), we moved the recording probes within a behavioral session to record units from different depths. In this case we scored two recording sessions per behavioral session.
cReaction time was not significantly different among task types. p value without Bonferroni correction for multiple comparison: 0.9670 for comparison between tactile task and auditory task (1.2 s delay); 0.0415 for comparison between tactile task and auditory task (2.0 s delay), based on Mann-Whitney U test.
