Expand description

Triplet STDP: considers timing of three spikes for more accurate visual cortex plasticity modelling.

Extends pair-based STDP with a slow post-synaptic trace o2 that gates potentiation and a slow pre-synaptic trace r2 that gates depression:

Δw⁺ = A₂⁺ · r1(t) · o2(t-ε) (triplet LTP) Δw⁻ = A₂⁻ · o1(t) · r2(t-ε) (triplet LTD)
