(A) Videography of a head-restrained mouse with four traced whiskers (from row C, labeled in green). (B) Simplified diagram of the cerebellar circuit (cf: climbing fiber; gc: granule cell; PC: …
(A) The fraction of time from all recordings (n = 47) that mice were engaged in locomotion during whisking was very small. (B) Distribution of whisker positions during a single recording session …
(A) Relative CS firing rate changes during whisking with respect to non-whisking CS rates for all significantly modulated units (n = 33, Mann-Whitney-Wilcoxon test, p<0.05). Red and blue symbols …
(A) Whisker movements and corresponding simple spike raster from a single PC across 20 epochs of free whisking. Neuron demonstrates increased SS frequency during movement. (B) Peri-event time …
CS peri-event time histograms (PETHs) overlaid with average whisker positions for the same cells shown in Figure 2. Note the absence of the close relationships between CS firing rate change and …
(A) Cross-correlation between whisker position and SS discharge for individual whisking bouts (gray lines) of a strongly modulated PC. Gray circles: time of peak correlation for individual bouts. …
Normalized cross-correlations measured at whisking onset (solid lines) and offset (dashed lines) for example PCs shown in Figure 2. The temporal relationship between whisking and SS modulation is …
(A) Relationship between SS rate and whisker position for PC with strong linear tuning in the forward direction only (unidirectional PC). Linear regression was performed for whisker positions …
(A) Relationship between whisker encoding range and PC gain. A strong inverse relationship was observed between linear encoding range and gain of SS modulation, indicating that high gain neurons …
(A) PC recordings in Crus I were performed during transient inactivation of contralateral motor cortex (M1; via local muscimol injection, see ‘Materials and methods’). (B) Relative SS firing rate …
(A) Example of rhythmic whisker movement (green trace), and corresponding phase (orange) derived from the Hilbert transform of the raw position trace. (B) Modulation depth of phase tuning for …
(A) Reconstruction of whisker movement from single PC SS train based on the calculated transfer function. Whisker set point information (purple) is accurately reconstructed (black trace, bottom) …
SS activity of a single PC during 15 s of voluntary whisking behavior. Left: Movements of the ipsilateral whisker pad were recorded via high-speed infrared videography. Top: changes in whisker angle …
SS activity of a single PC during 10 s of voluntary whisking behavior. Left: Movements of the ipsilateral whisker pad were recorded via high-speed infrared videography. Top: Fluctuations in the …
