Expand description

Dopamine-gated STDP: learning rate modulated by global reward signal.

Standard STDP with an eligibility trace gated by dopamine concentration. Weight updates only occur when dopamine is present:

dw/dt = DA(t) · e(t) de/dt = -e/τ_e + STDP(Δt) · δ(t_spike) dDA/dt = -DA/τ_DA + reward(t)
