Rat Hippocampus Theta-Gamma Oscillation Phase Coupling Analysis

Aggregating local field potential (LFP) recordings from the rat hippocampus, used to investigate cross-frequency phase-phase coupling between theta and gamma oscillations. The data was contributed by author Robson Scheffer-Teixeira and was last updated in June 2020. It includes simulated and actual LFP data analyzed to question the existence of theta-gamma phase-phase coupling.

Use Cases

• Analyze simulated and actual hippocampal LFPs to detect spurious theta-gamma phase-phase coupling introduced by filtering.
• Investigate the effects of epoch length on coupling levels in white noise and hippocampal LFP signals.
• Examine how waveform asymmetry and frequency harmonics may generate artifactual n:m phase-locking in neural oscillations.
• Apply appropriate statistical controls and surrogate methods to validate phase-phase coupling findings in neural data.

Strengths

• Dataset is associated with a peer-reviewed scientific publication questioning a specific neural mechanism.
• Data is provided under a permissive CC0 1.0 public domain license.
• Includes both simulated LFP data and actual recordings from rat hippocampus for methodological comparison.

Limitations

• The specific data structure, including row count, column names, and file formats, is unknown.
• The dataset's primary purpose is to demonstrate methodological pitfalls, which may limit its utility for general neural signal analysis.
• Data is from 2020 and may not reflect the most recent methodologies in the field.
