Nicotine self-administration induces CB1-dependent LTP in the bed nucleus of the stria terminalis.
Nicotine addiction is characterized by repetitive drug taking and drug seeking, both tightly controlled by cannabinoid CB1 receptors. The responsiveness of neurons of the bed nucleus of the stria terminalis (BNST) to infralimbic cortex (ILCx) excitatory inputs is increased in rats with active, but not passive, nicotine taking. Therefore, we hypothesize that acquisition of the learned associatio...
متن کاملDouble-dissociation of the catecholaminergic modulation of synaptic transmission in the oval bed nucleus of the stria terminalis.
The bed nucleus of the stria terminalis (BST) is a cluster of nuclei within the extended amygdala, a forebrain macrostructure with extensive projection to motor nuclei of the hindbrain. The subnuclei of the BST coordinate autonomic, neuroendocrine, and somato-motor functions and receive robust neuromodulatory monoaminergic afferents, including 5-HT-, noradrenaline (NA)-, and dopamine (DA)-conta...
متن کاملNeuropeptide Y and corticotropin-releasing factor bi-directionally modulate inhibitory synaptic transmission in the bed nucleus of the stria terminalis.
Neuropeptide Y (NPY) and corticotropin-releasing factor (CRF) have opposing effects on stress and anxiety. Both can modify synaptic activity through their binding to NPY receptors (YRs) and CRF receptors (CRFRs) respectively. The bed nucleus of the stria terminalis (BNST) is a brain region with enriched expression of both NPY and YRs and CRF and CRFRs. A component of the "extended amygdala", th...
متن کاملPresynaptic muscarinic M(2) receptors modulate glutamatergic transmission in the bed nucleus of the stria terminalis.
The anterolateral cell group of the bed nucleus of the stria terminalis (BNST(ALG)) serves as an important relay station in stress circuitry. Limbic inputs to the BNST(ALG) are primarily glutamatergic and activity-dependent changes in this input have been implicated in abnormal behaviors associated with chronic stress and addiction. Significantly, local infusion of acetylcholine (ACh) receptor ...
متن کاملStimulation of in vivo dopamine transmission in the bed nucleus of stria terminalis by reinforcing drugs.
Drugs of abuse preferentially increase dopamine transmission in the shell of the nucleus accumbens. This area is considered as a transition between the striatum and the extended amygdala a complex neural system that includes the central amygdala and the bed nucleus of stria terminalis, areas that, like the nucleus accumbens shell, are heavily innervated by mesolimbic dopamine neurons originatin...
