a Mean (±s.d.) peak responses of two example neurons tuned by (left) and insensitive (right) to displacement amplitude (dotted lines are linear regression fits, at least N = 5 repetitions per tested amplitude). Top, Δf/f0 mean (±s.d.) traces of the same neurons for three different amplitudes. b Amplitude sensitivity (% change in peak response for a doubling of movement amplitude) as a function of correlation coefficient (peak response vs. movement amplitude) of neurons tested with varying amplitudes. Top histogram: distribution of correlation coefficients across all neurons. Right histogram: distribution of amplitude sensitivity for neurons with significant correlation with movement amplitude (N = 86 neurons, 6 mice). The two example neurons in A are depicted with #1 and #2. c, d Data analogous to that in (a), (b) for neurons tested with varying velocities (N = 197 neurons, 8 mice). Source data are provided as a Source Data file.
