Presynaptically Silent GABA Synapses in Hippocampus

Bekkers, John


Mammalian central synapses commonly specialize in one fast neurotransmitter, matching the content of their presynaptic vesicles with the appropriate receptors in their postsynaptic membrane. Here, I show that hippocampal cultures contain autaptic glutamatergic synapses that contravene this rule: in addition to postsynaptic glutamate receptors, they also express clusters of functional postsynaptic GABAA receptors yet lack presynaptic GABA. Hence, these synapses are presynaptically silent with...[Show more]
