TMS-EEG Data on Parietal Cortex Function in Bistable Perception

Featuring concurrent transcranial magnetic stimulation and electroencephalography (TMS-EEG) recordings from participants viewing bistable stimuli, replay stimuli, or fixation. It was created by Georg Schauer and published in 2020 to investigate the causal role of the right parietal cortex in perceptual switching. The data is combined with individual structural MRI scans for source analysis.

Use Cases

• Analyze EEG time series data following TMS pulses to ant-SPLr and post-SPLr to compare neural responses between stimulation sites.
• Compare TMS-evoked potentials across experimental conditions (bistable stimulus, replay stimulus, resting-state fixation) to isolate perception-related neural activity.
• Use individual structural MRI scans to perform source localization of TMS-EEG signals within the parietal cortex.
• Investigate the temporal dynamics of neural activity in the right parietal areas during spontaneous perceptual alternations.

Strengths

• Data includes concurrent TMS and EEG recordings, allowing for causal investigation of brain function.
• Combined with individual participant structural MRI scans for anatomically precise analysis.
• Published under the permissive CC0 1.0 public domain license.

Limitations

• Sample size (number of participants) is not specified in the provided input.
• The specific file formats, data size, and column/variable definitions are unknown.
• Data is from a single study published in 2020, limiting temporal scope.
