(A) Synaptic architecture of the cortical and thalamic models. Both have a one-dimensional architecture, with the coupling between cells decaying with their distance. The footprint lengths are denoted by σ (3, 20). In the case of two populations, the first and second letters in the subscript denote the pre- and postsynaptic populations respectively. (A) Disinhibited cortical model: a chain of excitatory (E) cells. (B) Thalamic model. Inhibitory (I) RE cells inhibit excitatory (E) TC cells, and TC cells excite RE cells. Mutual inhibition between RE cells is neglected because it has relatively small effect on discharge propagation (16, 19). (C) Exponential (solid line) and square (dashed line) footprint shapes.
