Fig. 1: The IBL task, data types and behaviour.
From: A brain-wide map of neural activity during complex behaviour
a, Schematic of the IBL task and the block structure of an example session. b, Timeline of the events and analysed variables. Colours are used in other figures. c, Distribution of the times between stimulus onset and first wheel-movement time (interpreted as a reaction time) from 459 sessions. The distribution is truncated at 80 ms and 2 s. A total of 22.8% first wheel-movement times occurred under 80 ms (not shown). d, Proportions of correct choices (top) and first wheel-movement time (bottom) given a stimulus contrast (one point per mouse per contrast). Performance on 0% contrast trials (grey) was 58.7 ± 0.4% correct (mean ± s.e.m. across mice). Data are for 139 mice and 454 sessions. e, Proportions of correct choices given the number of trials before the end of the session for 0% (grey) and non-0% (black) contrast trials (mean ± s.e.m. across mice). f, The same analysis for first wheel-movement times. g, Reversal curves. Proportions of correct choices around a block change for trials with 0% contrast and >0% contrast (mean ± s.e.m. across mice; excluding the first 90 unbiased trials). h, Psychometric curves. Fraction of correct choices given a signed contrast (positive or negative for right or left stimuli, respectively) for all mice (one dot per contrast per mouse). Right choices were more or less common in right (red) or left (blue) blocks, with Pright = 0.8 and Pright = 0.2, respectively. i, Time series and trial information for three example trials: rotary encoder output of the wheel, video analysis and spike-time rasters across multiple brain regions. Figures are organized according to the IBL style (https://github.com/int-brain-lab/ibl-style/tree/main). Schematic in a was adapted from ref. 23, eLife, under a Creative Commons licence, CC BY 4.0.
