The<unk>  <unk>  tightly regulates the probability of   neurotransmitter release in a host of neuronal tissues like the hippocampus, amygdala, basal ganglia, and cerebellum    Data from immunologists, developmental biologists, and embryologists show that the<unk>  is also intimately involved in crosstalk between lymphocytes and synchronizing the timing between uterine receptivity and embryo implantation .  In the central nervous system, however, the<unk>  is involved in a specific type of retrograde signaling in which endogenous cannabinoids<unk> s) are released from the post-synaptic neuron and bind to nearby cannabinoid receptor 1 (CB1) -expressing presynapses; this binding elicits a sharp, but temporary, suppression of presynaptic neurotransmitter release . In this way, the post-synaptic neuron can regulate its own excitability by adjusting synaptic inputs via<unk> s that act as retrograde messengers.  The<unk>  is thought to be important in long-term potentiation and memory , motor learning , and synaptic plasticity .
