Figure 2.

Effects of muscimol on ³⁶Cl⁻ uptake by membrane vesicles prepared from the cerebral cortex of rats during pregnancy and after delivery. Membrane vesicles, prepared from rats on the indicated days, were incubated for 10 min at 30°C before the addition of ³⁶Cl⁻ in the absence (basal value) or presence of 5 μM of muscimol. Uptake of ³⁶Cl⁻ was terminated 5 s later. Data are expressed as the percentage increase in ³⁶Cl⁻ uptake induced by 5 μM of muscimol relative to the basal value and are means ± SEM of six different experiments, each performed with two rats per group. ∗, P < 0.05 vs. estrus.
