Time-resolved spectral parameterization: Recommendations and guidelines.

Guidelines for accurate time-resolved spectral parameterization improve analysis of neural oscillations and aperiodic activity at fine timescales.

• Why it matters: Understanding aperiodic activity is crucial for linking neural signals to cognition and disease, but practical and statistical challenges hinder reliable analysis.
• What they did: The authors offer recommendations on optimizing model fits, reporting analysis decisions, and handling failures in spectral parameterization across short, noisy data windows.
• The result: Implementing these guidelines enhances reproducibility and accuracy in studying the dynamics of neural activity, advancing insights into cognition, behavior, and neurological conditions.
