Fig. 4 — Responses of single neurons to grasp types and movements in individual joints. a Raw calcium (ΔR/R) traces for cell 2 (left) and cell 12 (right) from Fig. 3 during the three different grasp types and for both conditions. Corresponding average traces below for raw calcium traces (upper panel) and deconvolved spiking rate (SR) traces. b Percentages of the 486 recorded cells showing significant activity related to specific grasp types under both conditions (pooled across all nine recorded neuronal networks). c Percentages of the 486 recorded neurons showing significant prediction of specific forelimb joint angle changes under both conditions (two pies on the left, pooled across all nine recorded neuronal networks). In Figs. 3 and 4a, cell 2 is classified as finger-predictive and significantly active during digit-tip grasps; cell 12 is classified as shoulder-predictive. Pie on the right: Context specificity of significant joint-angle predictive cells from regular to irregular. Neurons significantly predicted a particular joint movement either only in the regular condition (Reg, cyan), or only in the irregular condition (Irreg, magenta), or in both conditions (Both, purple), or they swapped significant encoding of the respective joint from regular to irregular (J-Swap, orange)
