SPL_single_units_reaching_task

Summary

We publish six electrophysiological datasets obtained from three regions (V6A, PEc, PE) within the superior parietal lobule (SPL) of two Macaca fascicularis monkeys (MonkeyS and MonkeyF). The datasets were collected during an instructed delayed foveated reaching task conducted in the absence of light. The task involved reaching towards nine targets positioned at varying depths and directions relative to the monkeys' point of view. For each hemisphere, we have recorded neural activity from 285, 231, and 166 individual neurons in V6A, PEc, and PE, respectively. Additionally, the timing of the main behavioral events for each trial is included. The data is stored in .h5 files, which offer a convenient hierarchical structure and the ability to attach various types of information to each hierarchical level. To help you get started, we also provide example code in MATLAB and Python for understanding the data structure.
