Fig. 4.

Male and female responses and autoreceptor dynamics. The red dots in a, b show the experimental averages of (n = 23) male and (n = 23) female responses of extracellular serotonin, eht. The blue curves show the model simulations. Parameters for the simulations are given in Table 4 and discussed below. The dashed horizontal line is the average baseline concentration of eht in the CA2 region of the hippocampus. The male and female average responses are similar. c Shows the dynamics of the three variables, $B_{\mathit{ht}},G_{\mathit{ht}}^{\ast },T_{\mathit{ht}}^{\ast }$ of the serotonin $5H{T}_{1B}$ autoreceptor dynamics. “See the Discussion in the text”. The experimental data is replotted from [62]
