Example response time data

This dataset is a short slice of a high-density (HD-EEG) dataset from a study investigating the impact of deep brain stimulation on patients with advanced Parkinson's disease (Madetko-Alster, 2025). The data contains response times (time between stimulus presentation and pressing the button) from the experiment involving a simple visual-motor task. The study was carried out by Central European Institute of Technology in Brno and was supported by Czech Health Research Council AZV NU21-04-00445.

Example dataset contains response time values in individual experiment epochs for 2 representative subjects (one patient and one healthy control subject).

Usage

data("rtdata")

Format

The data frame consists of 29 rows (14 for subject 1, 15 for subject 2) and three columns:

subject

Factor variable with subject ID, 1 - representative healthy control subject, 2 - representative patient subject.

epoch

Factor variable with epoch number (14 epochs for subject 1, 15 epochs for subject 2).

RT

Response time in milliseconds.

Source

Central European Institute of Technology, Masaryk University, Brno, Czech Republic.

Details

The epochs and subjects correspond to the sample dataset epochdata.
