1 When photostimulation of genetically identified terminals is used to release only GABA, CB1R-dependent DSI persists for many minutes. gamma-Aminobutyric Acid cannabinoid receptor 1 (brain) Mus musculus
2 These observations suggest that heterologous interactions between mGluRs and CB1Rs control the temporal window of DSI at GABA synapses, providing evidence for a powerful new way to affect functional circuit connectivity in the brain.SIGNIFICANCE STATEMENT Postsynaptic depolarization liberates endocannabinoids, resulting in a rapid and transient decrease in release probability at GABA synapses. gamma-Aminobutyric Acid cannabinoid receptor 1 (brain) Mus musculus
