Exact neural mass model for synaptic-based working memory

Firing rates rk(t) of excitatory populations: blue, orange and green curves corresponds to k = 1, 2, 3 (A), while the black curve refers to k = 4, …, 7 (B). PBs of excitatory populations are shown in (C): horizontal lines in absence of dots indicate low activity regimes; coloured dots mark the PBs’ occurrences. The coloured bars on the time axis denote the presence of a stimulation pulse targeting the corresponding population. Only populations k = 1, …, 3 are stimulated in the present example. The spectrogram of the average membrane potential of population one v1(t) is reported in panel (D). Parameters: Npop = 7, ms,
