Extended Data Fig. 1: Multidirectional tongue-reaching behavior.
From: Connectivity underlying motor cortex activity during goal-directed behaviour
a, Videography of tongue trajectories in 4 behavioral sessions of one mouse in the multidirectional tongue reaching behavior. Vertical line (white) indicates the time of target appearance. In each trial (horizontal lines) the tongue location is color-coded according to its dorsal-ventral coordinate (normalized to the maximal dorsal-ventral tongue location detected in each session). Mice produced hundreds of trials already from the first behavioral session. b, Lick rate as a function of time from the target appearance. Red, the interval marking the target movement towards a reachable location (‘Target ON’); Blue, average target retraction time (‘Target OFF’). Target is retracted 1 s after reward delivery or maximal time-out time (Methods), therefore its retraction time (blue) is varied on each trial. Most licks occur within less than 2 s from the target appearance. c, Correlation between tongue horizontal location and target horizontal location during the trial. Data in b-c is displayed as mean ± s.e.m. across sessions. d-h, Lick statistics and tongue kinematics as a function of target location (top), session number (middle), or trial number in block of repeated target locations (bottom). Data in d-h is displayed as mean ± s.e.m. across mice (middle) or sessions (top, bottom).
