Music and the nucleus accumbens
Surgical and Radiologic Anatomy, 2014Music is a universal feature of human societies over time, mainly because it allows expression and regulation of strong emotions, thus influencing moods and evoking pleasure. The nucleus accumbens (NA), the most important pleasure center of the human brain (dominates the reward system), is the 'king of neurosciences' and dopamine (DA) can be rightfully

Spatial memory, plasticity and nucleus accumbens
Reviews in the Neurosciences, 2012Research on the function of the nucleus accumbens, the most ventral component of the striatal complex, has traditionally focused on locomotor activity, reward, motivation and addiction. However, based on the existence of projections to the nucleus accumbens from the allocortical regions involved in spatial navigation, it has been suggested that this ...

The nucleus accumbens and learning and memory
Journal of Neuroscience Research, 1997Recent research on the nucleus accumbens (NA) indicates that this brain region is involved in learning and memory processes in a way that is separable from its other well-known roles in behavior, such as motivation, reward, and locomotor activity. These findings have suggested that 1) the NA may be involved in declarative, or hippocampal formation ...

Interaction of the hypocretins with neurotransmitters in the nucleus accumbens [PDF]
Regulatory Peptides, 2002 The 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 ...

Neurochemical heterogeneity of the primate nucleus accumbens
Experimental Brain Research, 1995In order to further investigate the neurochemical anatomy of the primate nucleus accumbens (NAC), the distributions of the neuropeptides leucine-enkephalin (Leu-ENK), neurotensin (NT), and substance P (SP) and of haloperidol-induced c-fos expression were investigated in the macaque monkey using immunohistochemical methods.

Differential Modulation of Nucleus Accumbens Synapses
Journal of Neurophysiology, 2002The nucleus accumbens (NAcc) is a brain region involved in functions ranging from motivation and reward to feeding and drug addiction. The NAcc is typically divided into two major subdivisions, the shell and the core. The primary output neurons of both of these areas are medium spiny neurons (MSNs), which are quiescent at rest and depend on the ...

The efferent projections of the nucleus accumbens in the rat
Brain Research, 1977The efferent projections of the nucleus accumbens have been examined in the rat. This has been achieved by mapping the distribution of degenerating axons and terminals following the placement of small electrolytic lesions within the accumbens. Quantitatively, the majority of accumbens efferent fibres appear to terminate in the diencephalon, while there

Effect of nucleus accumbens destruction in rat
Experientia, 1984The paper presents the effects of nucleus accumbens destruction in rats. There are certain behavioral correlates (e.g., avoidance learning and dominance) which are influenced by the destruction of the nucleus accumbens, while other specific correlates are not significantly affected (namely, open field movements and competition for food).

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 ...

Nucleus accumbens stimulation in pathological obesity
Neurologia i Neurochirurgia Polska, 2016One of the potential treatment methods of obesity is deep brain stimulation (DBS) of nucleus accumbens. We describe the case of 19 years old woman with hypothalamic obesity. She weighted 151.4 kg before DBS and the non-surgical methods proved to be inefficient. She was treated with implantation of DBS electrode to nucleus accumbens bilaterally. Results
