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 کاملAdolescent nicotine alters dendritic morphology in the bed nucleus of the stria terminalis.
Adolescent nicotine increases dendritic elaboration in several areas associated with the extended amygdala. It also increases anxiety-like behavior in adulthood. An unresolved question is whether adolescent nicotine alters dendritic structure in the bed nucleus of the stria terminalis (BNST), which may contribute to altered anxiety-like behavior. To investigate this possibility, adolescent male...
متن کاملStress switches cannabinoid type-1 (CB1) receptor-dependent plasticity from LTD to LTP in the bed nucleus of the stria terminalis.
The bed nucleus of the stria terminalis (BNST) exerts a coordinated modulation of the psychoneuroendocrine responses to stress. However, how acute stress impacts on BNST in vivo plasticity is a crucial question that still remains unanswered. Here, neurons from the anterior portion of the BNST (aBNST) were recorded in vivo during and after stimulation of their medial prefrontal cortical (mPFC) a...
متن کاملNMDA-receptor-dependent plasticity in the bed nucleus of the stria terminalis triggers long-term anxiolysis
Anxiety is controlled by multiple neuronal circuits that share robust and reciprocal connections with the bed nucleus of the stria terminalis (BNST), a key structure controlling negative emotional states. However, it remains unknown how the BNST integrates diverse inputs to modulate anxiety. In this study, we evaluated the contribution of infralimbic cortex (ILCx) and ventral subiculum/CA1 (vSU...
متن کاملLocalization and Function of the Cannabinoid CB1 Receptor in the Anterolateral Bed Nucleus of the Stria Terminalis
BACKGROUND The bed nucleus of the stria terminalis (BNST) is involved in behaviors related to natural reward, drug addiction and stress. In spite of the emerging role of the endogenous cannabinoid (eCB) system in these behaviors, little is known about the anatomy and function of this system in the anterolateral BNST (alBNST). The aim of this study was to provide a detailed morphological charact...
