Fig. 3: Whisker-centric and allocentric coding in the thalamus.
From: Co-coding of head and whisker movements by both VPM and POm thalamic neurons
a Distributions of MDs (top) and modal values (bottom) of the neuronal tunings in VPM and POm for the primary whisking-related variables. b Cross-correlations of head and whisker kinematic variables from the entire recording session (190.2 s) of one mouse. The triggering variable is denoted on the top-left of the top panels and the other variable along the y-axis of the left column. X-axis values are time lags in ms (resolution 2 ms); y-axis values are correlation coefficients. Correlations of shuffled data are depicted by their mean (dark gray) and 1 SD (light gray). \({\theta }_{W,L}\), angle of left whisker beam; \({{{{{{\boldsymbol{\theta }}}}}}}_{{{{{{\boldsymbol{W}}}}}}{{{{{\boldsymbol{,}}}}}}{{{{{\boldsymbol{R}}}}}}}\), angle of right whisker beam; \({\dot{{{{{{\boldsymbol{\theta }}}}}}}}_{{{{{{\boldsymbol{W}}}}}}{{{{{\boldsymbol{,}}}}}}{{{{{\boldsymbol{R}}}}}}}\), angular velocity of right whisker beam; \({{{\phi }}}_{{{{{{\boldsymbol{W}}}}}}{{{{{\boldsymbol{,}}}}}}{{{{{\boldsymbol{R}}}}}}}\), phase of right whisker beam. c Preference of coordinate frame. The x-axis represents the MD exhibited by each neuron when coding the allocentric (whisking+head, \({\theta }_{W,{aX}}\) and \({\dot{\theta }}_{W,{aX}}\), see “Methods” section) variable minus its MD when coding the whisking variable alone (e.g., the panel labeled ‘\({\theta }_{W,L}\)’ represents the MD of \({\theta }_{W,{aL}}\) minus the MD of \({\theta }_{W,L}\)). VPM and POm distributions were significantly different for \({\theta }_{W,L}\) (p = 0.008) and not for the other variables (p > 0.08); permutation tests.
