The Cell

Click a component to inspect it. Press Start to run the loop (it also gives it a kick); Reset draws a fresh run.

V · membraneMembrane potential. Sawtooth: it charges toward threshold under input, then hard-resets on each spike. A steeper rise means stronger drive.—

ϑ · thresholdFiring threshold. Steps up after each spike (adaptation + homeostat) and decays between: the moving bar the membrane must beat to fire again.—

a · adaptSpike-frequency adaptation. Jumps on every spike and relaxes slowly; a high level means the cell has been firing a lot and is self-braking.—

r̄ · rateLow-pass estimate of the cell's own firing rate. Sitting flat near the target set-point means the two slow homeostats are balanced.—

e · eligEligibility trace. Builds on pre·post spike coincidence and decays otherwise: the synapse 'tagged' for change, awaiting the third factor.—
