Abstract

The reason why neurons synthesize more than one endocannabinoid (eCB) and how this is involved in the regulation of synaptic plasticity in a single neuron is not known. We found that 2-arachidonoylglycerol (2-AG) and anandamide mediate different forms of plasticity in the extended amygdala of rats. Dendritic L-type Ca(2+) channels and the subsequent release of 2-AG acting on presynaptic CB1 receptors triggered retrograde short-term depression. Long-term depression was mediated by postsynaptic mGluR5-dependent release of anandamide acting on postsynaptic TRPV1 receptors. In contrast, 2-AG/CB1R-mediated retrograde signaling mediated both forms of plasticity in the striatum. These data illustrate how the eCB system can function as a polymodal signal integrator to allow the diversification of synaptic plasticity in a single neuron.

  • Additional reports indicate TRPV1 expression in the bed nucleus of the stria terminalis, hippocampal dentate gyrus, and hippocampal CA1 region in postsynaptic terminals of both inhibitory and excitatory synapses.

    “there are additional reports of TRPV1 expression in the bed nucleus of the stria terminalis (BNST) (Puente et al., 2011), hippocampal dentate gyrus (Canduela et al., 2015; Lee et al., 2015; Puente et al., 2015) and hippocampal CA1 region (Lee et al., 2015) in postsynaptic terminals of both inhibitory (Canduela et al., 2015; Lee et al., 2015) and excitatory synapses (Puente et al., 2011; Puente et”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
