Structure-Constrained Intrinsic Timescales Across Tasks

The paper maps intrinsic neural timescales across rest and tasks, showing task-induced changes while preserving temporal hierarchy and structural constraints.

Cross-Frequency Coupling as a Neural Substrate for Prediction Error Evaluation: A Laminar Neural Mass Modeling Approach

This paper proposes that cross-frequency coupling (CFC) mechanisms in a laminar neural mass model support prediction error evaluation in predictive coding, with implications for disorders like Alzheimer's disease and the effects of serotonergic psychedelics.

Emergence of multifrequency activity in a laminar neural mass model

This paper analyzes a laminar neural mass model to show it can generate periodic, quasiperiodic, and chaotic oscillations, including cross-frequency couplings, and examines how Alzheimer's disease affects these dynamics.
