Intracellular free calcium levels: Intracellular free calcium levels were estimated according to the method of Luo and Shi (Luo and Shi‚ 2005). Briefly‚ hippocampi were isolated from mice brains and subjected to hippocampal cells isolation as described later. The cells obtained were incubated with Fura-2 AM at 37°C with gentle shaking. The fura-2 loaded suspension was centrifuged for 10 minutes‚ pellet was washed once with Ca2+-free buffer and was centrifuged again. Aliquots of the washed suspension
