| Abstract: | Rat olfactory bulb slices were preloaded with [3H] taurine or with [14C] GABA. Upon stimulation of the slices with increasing concentrations of KCl, we observed release of [3H] taurine or [14C] GABA. Superfusion of the slices with high concentrations of K+ in the absence of Ca2+ in the perfusion medium, led to a marked decrease in the stimulated release of both [3H] taurine and [14C] GABA. |
