... In the case of fast excitatory Rsynapses, r(t) can be calculated from the marginal distribution in v: fV (v, t) = ρ(v, g, s, t)dg ds. Thus, we can reduce the dimension back to one by computing just fV (v, t). The evolution equation for fV , obtained by integrating (3) with respect to ~x = (g, s), de ...
