Fig. 2: Thalamic coding of whisking and head kinematics.
From: Co-coding of head and whisker movements by both VPM and POm thalamic neurons
a Simultaneous recordings of head and whisker kinematics (lower traces; “whisker beams” refer to the median rotation angle of all tracked whiskers in a given side, see “Methods” section) and single-unit spike activity (top trace, each bar indicates spike time of a single unit). The gray shading indicates periods of object contact. b Examples of single-unit tuning curves for primary whisking-related variables (offset (\({\theta }_{{off}}\)), angle (\({\theta }_{W}\)), angular velocity (\({\dot{\theta }}_{W}\)), phase (\({\varnothing }_{W}\)) and frequency (\({f}_{W}\)). Tuning curves of shuffled data are depicted by their mean (dark gray) and 1 SD (light gray). Purple, POm; Green, VPM. Each curve, of both empirical and shuffled data, is normalized to its maximal value; the firing rates labeling the ordinate in each plot refer to the empirical data only. c Fraction of tagged units coding each of the whisker kinematic variables (for either side of the snout) and head kinematic variables, computed for each nucleus separately (fraction values are not additive across nuclei). Number of units (n) appear on the right y-axis. Source data are provided as a Source Data file.
