Seizure recruitment

This experiment asks when a finite burst remains focal and when directed coupling recruits a chain of neighboring regions. The classification is tied to continuous regional activity and onset times.

Prompt

Start a seizure-like burst in one brain region and show when it remains local and when it recruits neighboring regions.

Agent decision path

1. Classify the task as aggregate multi-region dynamics.

2. Route regional activity and coupling to brainmass.

3. Select a four-region FitzHughNagumoStep chain with directed additive coupling.

4. Deliver a finite pulse only to region 0 and preserve a fixed-capacity delay history.

5. Define recruitment before the sweep as V >= 0.5 for at least 1 ms.

6. Map coupling, propagation delay, and pulse amplitude across complete independent rollouts.

7. Keep delay and duration unit-bearing while retaining peak activity and onset for every region.

8. Verify delay phase and ordered recruitment with focused tests.

Result

At coupling 0.15 and pulse 0.35, only region 0 is recruited. At coupling 0.45 and pulse 0.50, all four regions recruit in order at 6.4, 9.5, 12.8, and 16.5 ms. The sweep evaluates 80 parameter combinations.

Fig. 3 Ordered onset times distinguish propagation from simultaneous activation, while the sweep shows where distal recruitment is absent or present.
