Effect of AAV.ALP or AAV.ERα and EB or OIL pretreatment on K+-evoked GABA in dialysate from striatum. A. The time course of the effect of AAV.ALP and EB or OIL pretreatment on K+- evoked GABA in dialysate from striatum. B. The time course of the effect of AAV.ERα and EB or OIL pretreatment on K+- evoked GABA in dialysate from striatum. For A & B: The bar depicts the period during which K+ was dialyzed into striatum through the dialysis probe. * There was a main effect of treatment (F 3,29 = 4.28, p<0.013), a treatment X time interaction (F 29, 426 = 2.94, p<0.0001); and an effect of time of sample collection (F 29, 142 = 126.37, p<0.0001). C. Effect of AAV.ALP or AAV.ERα and EB or OIL pretreatment on the mean increase in K+- evoked GABA in dialysate from striatum. *AAV.ALP+EB less than AAV.ALP+OIL (p<0.043). ** AAV.ERα + EB less than AAV.ERα + OIL (p<0.002), and AAV.ALP + EB (p<0.02). There was no significant difference between the oil treated groups.
