The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Rhythm switching was supported by multiple coexisting mechanisms: turnover of the active subpopulation, network-wide baseline shifts that reposition the operating point near distinct unstable fixed points, and inter-neuronal phase reorganization that selectively cancels or supports band components in the population output. The mechanism deployed for each mode pair varied across training runs, exposing a degeneracy of learned solutions.

C2weakest assumption

That the mechanisms observed in these simplified leaky-integrator RNNs trained on an artificial four-band switching task provide a valid framework for interpreting frequency-band-specific functional differentiation in biological neural circuits.

C3one line summary

Leaky integrator RNNs with adaptive time constants switch between four frequency bands using multiple mechanisms including subpopulation turnover, baseline shifts, and phase reorganization, with high frequencies dominated by short-time-constant neurons.
