Fig. 2From: Adaptation and Fatigue Model for Neuron Networks and Large Time Asymptotics in a Nonlinear Fragmentation EquationTotal neural activity N(t) computed with α=4 and K(s,u)= δ s = 0 . Left: initial data as e − s . Right: a more complex initial data (as in Proposition 2 of [17]). We see that two different periodic solutions occur with those two different initial data. The continuous lines give the values N − and N + Back to article page
