Extracellular neural recordings from macaque primary and dorsal premotor motor cortex during a sequential reaching task

This data set includes extracellular recordings and behavior of macaque used in Lawlor, P.N. et al 2018 (under review as of 1/2018). The data was collected by Matthew G. Perich in the laboratory of Lee E. Miller at Northwestern University. The experiments examined the role of premotor cortex (PMd) and primary motor cortex (M1) in a sequential reaching task. In the experiment, the monkey controlled an on-screen cursor and was rewarded for moving that cursor to an indicated reach target, with multiple targets presented per trial. There were minimal kinematic requirements for the reaching movements (e.g., very brief hold times), meaning that the monkey typically made a relatively smooth series of reaches. Behavioral variables recorded include position, velocity, and acceleration. Reach target locations and approximate presentation times are included. The electrophysiological recordings were collected with Utah multielectrode arrays from two monkeys.

本数据集涵盖Lawlor P.N.等人2018年研究（2018年1月处于审稿阶段）中使用的猕猴细胞外电生理记录与行为学数据。该数据集由Matthew G. Perich于西北大学（Northwestern University）Lee E. Miller实验室完成采集。本次实验探究了运动前皮层（premotor cortex, PMd）与初级运动皮层（primary motor cortex, M1）在序列到达任务中的功能机制。实验中，猕猴操控屏幕光标，将光标移动至指定到达目标即可获得奖励，且每次试次会呈现多个到达目标。该到达动作仅需满足极低的运动学要求（例如极短的停留时长），因此猕猴通常会完成一系列相对平滑的到达动作序列。记录的行为学变量包括位置、速度与加速度。数据集同时包含到达目标的位置信息以及大致呈现时间。电生理记录采用犹他多电极阵列（Utah multielectrode arrays）从两只猕猴身上采集获得。
