Glucose-monitoring neurons in the nucleus accumbens
NeuroReport, 2007The nucleus accumbens, a key structure of the limbic circuitry, is involved in the regulation of motivated behaviors. The accumbens performs its roles via interconnections with brain areas where glucose-monitoring neurons have been localized. To search for such integrative chemosensory cells here, extracellular single neuron activity was recorded in ...

Histamine: Correlative studies in nucleus accumbens
Journal of Neurobiology, 1982AbstractThe role of histamine as a neurotransmitter has been the subject of considerable controvery. Recent evidence suggests it to be involved in such complex activities as arousal and affect. The purpose of the present study is to examine the possible source, function, and pharmacology of histamine in the nucleus accumbens, an area of the brain also ...

Cholecystokinergic Innervation of Nucleus Accumbens Subregions
Peptides, 1998Behavioral and pharmacological evidence has shown a different and opposite role of the neuropeptide cholecystokinin (CCK) on the dopamine (DA) function in the caudal versus rostral part of the nucleus accumbens. Previous reports have speculated that the caudal region of the nucleus accumbens would receive CCKergic innervation from dopaminergic neurons ...

Modulation of Cell Firing in the Nucleus Accumbens
Annals of the New York Academy of Sciences, 1999ABSTRACT:Pennartzet al.48have proposed that functions of the nucleus accumbens (NA) are subserved by the activity of ensembles of neurons rather than by an overall neuronal activation. Indeed, the NA is a site of convergence for a large number of inputs from limbic structures that may modulate the flow of prefrontal cortical information and contribute ...

Interaction of the hypocretins with neurotransmitters in the nucleus accumbens
Regulatory Peptides, 2002The hypocretins (hcrt1 and hcrt2), also known as orexins, are two neuropeptides derived from the same precursor, expressed in a few thousand cells in the lateral hypothalamus. Hypocretin-containing cells project throughout the brain, including ascending projections to the olfactory bulb and cerebral cortex, through the medial septum and the nucleus ...

Reinforcing effects of morphine in the nucleus accumbens
Brain Research, 1982The possibility that morphine exerts in reinforcing effects via an action in the nucleus accumbens was investigated in the rat using the self-administration model and the method of intracerebral injection. Male, adult rats implanted with a chronic cannula aimed at this nucleus were tested for self-administration in a rectangular chamber equipped with ...
