Pre-injury tasks. (A) Example perievent histograms from the behavioral task and the pre-injury BMI tasks. Neurons recording during the behavioral task exhibited a wide range of responses from the time of cue onset. Here, one neuron maximally encodes information about press duration at longer latency (~2 s, short press ends, long press continues) while another neuron, although clearly modulated by the movement, encodes no information about press duration. For both pre-injury BMI tasks, information is encoded maximally at shorter and shorter latencies to cue-onset. (B) Neurons on average encoded significantly more information about press duration (spike timing) at significantly shorter latencies (C) as animals moved from behavioral control to BMI-o, while there was no change in spike count information. ^*p < 0.05; ^***p < 0.001.
