Dataset of intracranial EEG during cortical stimulations evoking negative motor responses

In this dataset we included iEEG recordings of responses to 41 intracranial high frequency stimulations evoking
negative motor responses, in 23 patients undergoing stereo-EEG presurgical evaluation for drug-resistant epilepsy.

The dataset contains 24 seconds of iEEG data around each stimulation, 9-10 seconds before the start of the stimulation,
up to 5 seconds of intracranial stimulation and 9-10 seconds after the end of the stimulation. Each recording contains
two 5 second epochs, pre-stimulation (used as baseline in the connectivity analysis) and post-stimulation.

We have used high-frequency bipolar stimulations of different areas of the brain, using biphasic pulses having a duration
of 1 ms, at a frequency of 43.2 Hz (alternating polarity) or 50 Hz (non-alternating), current intensity between 0.25 to 3 mA,
for up to 5 s.

The contact pair on which stimulation is applied, the current intensity level and evoked effect are specified
in the events tsv.

Not all patients in which stimulations evoked negative motor responses met the inclusion criteria for network analysis
that requires running the freesurfer pipeline, for instance patients having prior resections, therefore there are subjects
that do not contain anatomy data and are not included in the dataset. However, they are included in the numbering of patients
to match the table in the companion manuscript.
