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
ABSTRACTThere 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 participant with ...

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.

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 ...

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: an interface between cognition, emotion, and action.

Annual Review of Psychology, 2015
Nearly 40 years of research on the function of the nucleus accumbens (NAc) has provided a wealth of information on its contributions to behavior but has also yielded controversies and misconceptions regarding these functions.
