WebA pool of readily releasable quanta has been defined for hippocampal synapses ( 21 ) and retinal amacrine cell synapses ( 5 ) in culture. This pool consists of about 12 quanta per synapse, and when the pool has been completely depleted, replenishing it takes about 10 s in hippocampal synapses. WebJun 1, 1996 · A pool of readily releasable quanta has been defined for hippocampal synapses ( Stevens and Tsujimoto 1995) and retinal amacrine cell synapses ( Borges et al. 1995) in culture. This pool consists of about 12 quanta per synapse, and when the pool has been completely depleted, replenishing it takes about 10 s in hippocampal synapses.
