Description

LFP recordings from human subthalamic nucleus, filtered for beta and theta band oscillations, epoched around cue stimulus presentation, in a sequential decision making paradigm. STN-LFP signals recorded referenced to a common cephalic reference (right mastoid).

Additional source files, with raw LFP for STN and raw source-reconstructed time courses from MEG source signals. Continuous data were downsampled at 150Hz, bandpass filtered 48-52 Hz, and then MEG signals were beamformed using LCMV and significant vertices extracted based on sensor level results, finally epoched around cue presentation.

This is data for Figure 2 and Figure 4 in preprint 'Conflict detection in a sequential decision task is associated with increased cortico-subthalamic coherence and prolonged subthalamic oscillatory response in the beta band' on bioRxiv.

Graph showing beta signalled local conflict, and carried over this effect to the next cue in a sequence.
