Single-neuron spike trains from macaque prefrontal and secondary somatosensory cortex during a vibrotactile frequency-discrimination working-memory task

This repository contains neurophysiological recordings and behavioral variables from two macaque monkeys (RR11 and RR13) performing a vibrotactile frequency-discrimination task. Recordings were obtained from the secondary somatosensory cortex (S2) in RR11, and from both the prefrontal cortex (PFC) and S2 in RR13. On each trial, a first stimulus frequency (f1) and a second stimulus frequency (f2) were presented sequentially, separated by a delay period; the monkey had to compare them and report which frequency was higher. More information is provided in the data description document (README.pdf) included with the dataset. This dataset is published together with the following manuscript: • L. Serrano-Fernández, R. Romo, & N. Parga, Early emergence of perceptual biases in the secondary somatosensory cortex, Proc. Natl. Acad. Sci. U.S.A. 122 (52) e2519255122 (2025).
