Nucleus accumbens and impulsivity

Progress in Neurobiology, 2010
The multifaceted concept of impulsivity implies that different impulsivity aspects, mediated by different neural processes, influence behavior at different levels. The nucleus accumbens (NAc) is a key component of the neural processes regulating impulsivity.

Connections of the nucleus accumbens

Brain Research, 1976
Reports from previous works has given different classifications for the nucleus accumbens. There also appears to be a general lack of information regarding the fiber connections of the nucleus. The present investigation was undertaken to clarify the connections of this structure.

Appetitive Mapping of the Human Nucleus Accumbens

Biological Psychiatry, 2022
ABSTRACT There is strong evidence for the putative role of the nucleus accumbens (NAc) in appetitive motivation. A first-in-human feasibility trial of responsive deep brain stimulation (rDBS) for loss of control eating provided a rare opportunity to examine the physiologic and structural underpinnings of NAc function in a human ...

Music and the nucleus accumbens

Surgical and Radiologic Anatomy, 2014
Music 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

Nucleus Accumbens Surgery for Addiction

World Neurosurgery, 2013
Opiate addiction remains intractable in a large percentage of patients, and relapse is the biggest hurdle to recovery because of psychological dependence. Multiple studies identify a central role of the nucleus accumbens (NAc) in addiction; several studies note decreased addictive behavior after interventions in this area.Based on animal experiments ...

Projections of the Nucleus Accumbens in the Cat

Psychiatry and Clinical Neurosciences, 1989
Abstract: Due to the recent advances in knowledge on the function of the limbic sys tem it would be wise to consider this system as being widely distributed throughout the diencephalic and mesencephalic levels as well as the forebrain. Numerous regions have been discovered that are related to the limbic structures in anatomical and functional respects.

Dopamine action in the nucleus accumbens

Journal of Neurophysiology, 1985
The action of dopamine was studied in the nucleus accumbens of acutely prepared rabbits. Dopamine was applied iontophoretically to those cells and cell populations that responded in a monosynaptic excitatory manner to ipsilateral fimbrial stimulation. This strategy was adopted to isolate the effects of dopamine on postsynaptic receptors thus avoiding ...

The nucleus accumbens and learning and memory

Journal of Neuroscience Research, 1997
Recent 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 ...

Characterization of fimbria input to nucleus accumbens

Journal of Neurophysiology, 1985
The hippocampal input to the nucleus accumbens was studied by correlative electrophysiological and anatomical techniques in acutely prepared rabbits. Field and extracellular unitary potentials were recorded in the nucleus accumbens following ipsilateral fimbria stimulation.

Increased volume of the nucleus accumbens in schizophrenia

Journal of Neural Transmission, 2001
The nucleus accumbens, an integral and important part of limbic and prefrontal cortico-striato-pallidal-thalamic circuits, is involved in several cognitive, emotional and psychomotor functions altered in schizophrenia. In animal models, developmental disturbances within the entorhinal cortex and the hippocampus induce a dysregulation of inputs to the ...
