Neural Geometry from Mixed Sensorimotor Selectivity for Predictive Sensorimotor Control
Description
Sorted spike data recorded from the primary motor cortex (M1) of three monkeys , with Utah-array (Blackrock Microsystems), and example code to reproduce the major results. More details could be found in this article: Zhang Yiheng, Chen Yun, Wang Tianwei, Cui He (2024) Neural Geometry from Mixed Sensorimotor Selectivity for Predictive Sensorimotor Control, eLife, 13:RP100064 https://doi.org/10.7554/eLife.100064.1

Steps to reproduce
The 'neural data' folder includes all the binned firing rate of each sorted unit in individual behaviral trial. The 'example code\main.m' is to plot the main result: 1. example neuronal PSTH (Fig.1D, Fig.S2) and single neuron fitting (Fig. S5); 2. decoding (Fig.2A, 2B); 3. neural state (Fig.2C, 2D & Fig.3) The 'example code\simulation neural state\fig4_idealNeuronPCA.m' simulates the neural state of three-group ideal modulation neuron (Fig.4). The 'example code\ctrl hand velocity' folder includes the hand trajectory data and code for testing hand-speed effect (Fig. S1 & S11). The 'example code\SVR\SupplFig_Decode_ReachDir_TargetDir_SVR.m' compares the continous decoding results of two variables, target location and reach direction (Fig. S7A). All codes were ran in Matlab 2018b unless specified.
