Enhanced motivation to take drugs is a central characteristic of addiction, yet the neural underpinning of this maladaptive behavior is still largely unknown. Here, we report a D1-like dopamine receptor (DRD1)-mediated long-term potentiation of GABAA-IPSCs (D1-LTPGABA) in the oval bed nucleus of the stria terminalis that was positively correlated with motivation to self-administer cocaine in ra...
Introduction: The bed nucleus of the stria terminalis (BST) is a limbic structure which is involved in cardiovascular regulation and baroreflex modulation. The presence of cholinergic synaptic terminalis with high level of muscarinic receptors in the BST has been demonstrated. This study was performed to find the role of the cholinergic muscarinic receptor in cardiovascular response and baro...
The central extended amygdala is an evolutionarily conserved set of interconnected brain regions that play an important role in threat processing to promote survival. Two core components of the central extended amygdala, the central nucleus of the amygdala (Ce) and the lateral bed nucleus of the stria terminalis (BST) are highly similar regions that serve complimentary roles by integrating fear...
Previous comparative studies have suggested that the distribution of arginine vasopressin (AVP) pathways within the brain is associated with species-typical patterns of social behavior. In the current study, male parental behavior and aggression were compared in two species of Peromyscus. As predicted based on other studies, male mice from a monogamous species, the California mouse Peromyscus c...
3H-Guanidinoethylmercaptosuccinic acid (GEMSA) selectively labels the carboxypeptidase B-like enzyme enkephalin convertase (EC) in rat brain tissue sections. We have used autoradiography with 3H-GEMSA to map membrane-bound EC in the rat forebrain and, in conjunction with lesioning techniques, to localize EC to specific neuronal pathways. The highest levels of EC are in the median eminence. High...
Abstract Controllability over stressors has major impacts on brain and behavior. In humans, however, the effect of controllability responses to is poorly understood. Using functional magnetic resonance imaging (fMRI), we investigated how altered a shock-plus-sound stressor with between-group yoked design, where participants in controllable uncontrollable groups experienced matched exposure. Emp...
The effects of permanent forebrain lesions on conditioned taste aversions (CTAs) and conditioned odor aversions (COAs) were examined in 3 experiments. In Experiment 1, lesions of the bed nucleus of the stria terminalis had no influence on CTA or COA acquisition. Although lesions of the lateral hypothalamus induced severe hypodipsia in Experiment 2, they did not prevent the acquisition of CTAs o...
