Speech motor cortex enables BCI cursor control and click

One human participant (T15) with four 64-channel microelectrode arrays (256 neural recording channels) implanted in his cortex performed brain-computer interface (BCI) 2-D cursor control tasks, i.e., he used his brain (no physical muscle movement) to move and click a cursor to select targets on a computer screen. T15's arrays were located in his ventral precentral gyrus (vPCG), canonically considered speech motor cortex. Nevertheless, T15's imagery while moving the cursor was motoric (either attempting hand movements, tongue movements, or generic \"intuition\" of where he wanted to move the cursor), not speech.
Data streams in this dataset include task state (e.g., target position, cursor position) and neural features (threshold crossings, spike band power) for each recording channel, binned in 10 ms bins. Output from the neural decoders (predicted cursor velocities and click events) that was used online is also included., , # Data from: Speech motor cortex enables BCI cursor control and click

## Overview

For details about the study and the tasks, see the associated manuscript [Singer-Clark et al. 2025, \"Speech motor cortex enables BCI cursor control and click\"](https://doi.org/10.1088/1741-2552/add0e5). Additionally, the tasks are briefly summarized below.

* **Radial8 Calibration Task**
* On the computer screen, there was a circular white cursor, and circular gray targets arranged in a circle.

They do not contain any personally identifiable information. The subject is referred to using a coded clinical trial identifier (also used in the associated publication). Raw neural data are not shared; only de-identified processed neural features. Behavioral data do not contain identifiable information.
