Long-term recordings of motor and premotor cortical spiking activity during reaching in monkeys

This dataset contains electrophysiology and behavioral data from three macaques performing either a center-out task or a continuous random target acquisition task. Neural activity was recorded from chronically-implanted electrode arrays in the primary motor cortex (M1) or dorsal premotor cortex (PMd) of four rhesus macaque monkeys. A subset of sessions includes recordings from both regions simultaneously. The data contains spiking activity—manually spike sorted in three subjects, and threshold crossings in the fourth subject—obtained from up to 192 electrodes per session, cursor position and velocity, and other task related metadata.本数据集包含三只猕猴执行中心向外伸手任务（center-out task）或连续随机目标获取任务时产生的电生理与行为学数据。研究人员通过慢性植入的电极阵列，在四只恒河猴的初级运动皮层（M1）或背侧前运动皮层（PMd）中记录了神经活动。部分实验会话同时采集了两个脑区的神经活动。该数据集包含每会话最多192个电极采集得到的锋电位活动——其中三只受试个体的数据经手动锋电位分选处理，第四只受试个体的数据为阈值穿越信号——、光标位置与速度信息，以及其他与任务相关的元数据。
