... when 2πf t = 0 mod 2π and P2 is redrawn when 2πf t = π2 mod 2π, which introduces novelty and cancels the periodicity. After a short relaxation (200 ms), the STDP plasticity is activated for 5 s on the excitatory synapses of excitatory neurons only. We represent in figure 1 the population response in ...
