Apr 01, 2007 · Marijuana affects neural functions through the binding of its active component (Δ 9-THC) to cannabinoid receptors in the CNS.Recent studies have elucidated that endogenous ligands for cannabinoid receptors, endocannabinoids, serve as retrograde messengers at central synapses.
A The Role of Endocannabinoid Signaling in Motor Control ... The importance of endocannabinoids for short- and long-term synaptic plasticity and the underlying mechanisms have been thoroughly reviewed in recent years. In this review, we will instead focus on the role of endocannabinoid-mediated synaptic plasticity in motor systems using examples from CNS regions involved in motor behavior. Endocannabinoid System and Synaptic Plasticity ... Despite the fact that most of the studies on this field have been performed using in vitro models, endocannabinoid-mediated plasticity might be considered as a plausible candidate underlying some of the diverse physiological functions of the endogenous cannabinoid system, including developmental, affective and cognitive processes.
Endocannabinoid-mediated retrograde signaling is a fundamental counterpart of anterograde synaptic transmission throughout the CNS. However, despite decades of dedicated research, our understanding of the governing principles of endocannabinoid signaling at the molecular, synaptic and circuit levels has remained rather limited.
Endocannabinoid‐mediated short‐term synaptic plasticity: depolarization‐induced suppression of inhibition (DSI) and depolarization‐induced suppression of excitation (DSE) . 2‐AG and anandamide are two of the putative endocannabinoids presumed to mediate the effects of CB1Rs in the CNS (Devane et al., 1992; the exact nature of Parsing the players: 2‐arachidonoylglycerol synthesis and ... The involvement of these latter two pathways in the production of 2‐AG in the CNS has not been evaluated in detail but may account for some reports of endocannabinoid‐mediated synaptic plasticity that is insensitive to DAGL inhibitors (Zhang et al., 2011). REVIEW: Mechanisms of Long-Term Plasticity of Hippocampal ...

Retrograde Endocannabinoid Signaling. The first demonstration of retrograde eCB signaling came from the discovery that eCBs mediate forms of short-term synaptic plasticity known as depolarization-induced suppression of inhibition (DSI) (Ohno-Shosaku et al., 2001; Wilson and Nicoll, 2001) and depolarization-induced suppression of excitation (DSE) (Kreitzer and Regehr, 2001). Endocannabinoid-Mediated Synaptic Plasticity | SpringerLink Endocannabinoids are a component of the endocannabinoid signaling system, which comprises the endocannabinoids, the enzymes that synthesize and degrade endocannabinoids, and cannabinoid receptors. Within the central nervous system (CNS), endocannabinoids serve as modulators of both long-term and short-term synaptic plasticity.

Apr 01, 2008 · 4.4 Endocannabinoid-mediated spike timing-dependent plasticity (STDP) Another form of persistent synaptic plasticity where endocannabinoids have been implicated is in some types of spike timing-dependent plasticity (STDP) (Dan and Poo, 2006, Kampa et al., 2007). STDP is a form of synaptic plasticity that occurs following repeated pairing of Synaptic Targets of Δ9-Tetrahydrocannabinol in the Central ...

Mar 01, 2015 · Introduction. Endogenous cannabinoids (endocannabinoids, eCBs) are important regulators of synaptic function in the nervous system. In particular, endocannabinoids acutely modulate inhibitory and excitatory transmission throughout the forebrain, and mediate several forms of short-term plasticity at GABAergic and glutamatergic synapses, including depolarization-induced suppression of … Cooperative endocannabinoid production by neuronal ...
