MEG and cTBS Data on Theta-Gamma Oscillations During Memory Retrieval

Data from a study using magnetoencephalography (MEG) and continuous theta burst stimulation (cTBS) to investigate the causal role of the precuneus in network-wide theta and gamma oscillatory activity during complex memory retrieval. The dataset, authored by Melissa Hebscher and released in 2020, originates from research conducted in Toronto. It provides measurements of brain activity and stimulation effects related to memory processes.

Use Cases

• Analyze MTL-posterior neocortical theta phase coupling data to model network communication during memory retrieval.
• Investigate theta-gamma phase-amplitude coupling patterns before and after precuneus cTBS to assess causal effects on oscillatory activity.
• Examine MTL-neocortical communication metrics to understand how stimulation modulates theta and gamma oscillatory coupling.
• Use MEG-derived oscillatory activity data to study the mechanistic role of the precuneus in coordinating cross-regional interactions for remembering.

Strengths

• Data is derived from a controlled experimental setup combining MEG brain imaging with cTBS neuromodulation.
• Dataset is openly available under the permissive CC0 1.0 license.
• Research provides a causal investigation of a specific brain region (precuneus) in memory-related oscillatory activity.

Limitations

• The sample size (number of participants or recording sessions) is not specified in the provided input.
• Specific data variables, file formats, and the overall dataset size are unknown, limiting immediate usability assessment.
• Data is from a single study location (Toronto), which may limit the generalizability of findings.
