Jan 7, 2024 · Your nucleus accumbens is a powerhouse for two reasons. First, this region regulates a substance known as dopamine. Dopamine is a neurotransmitter—a chemical used by neurons—critical to reward ...
Jul 1, 2015 · Objective. The human nucleus accumbens (Acc) has become a target for deep brain stimulation (DBS) in some neuropsychiatric disorders. Nonetheless, even with the most recent advances in neuroimaging it remains difficult to accurately delineate the Acc and closely related subcortical structures, by conventional MRI sequences.
The nucleus accumbens is located at the anterior end of the striatum in the ventral part of the forebrain. It receives a variety of inputs from limbic structures, such as the amygdala, hypocampal formation, and bed nucleus of the stria terminalis.
The nucleus accumbens (NAc) is a key node of the brain’s circuitry that is responsible for translating motivation into action. It has been implicated in playing critical roles in virtually all forms of adaptive and pathological motivated behaviors. It is subject to modulation by a broad array of inputs that influence NAc activity in complex ...
Objectives. Identification, delimitation, and stereotactic localization of the human nucleus accumbens (Acc) in order to allow its accurate definition and three-dimensional targeting on magnetic resonance imaging (MRI) enabling its use for deep brain stimulation. Methods. Magnetic resonance imaging …
Oct 22, 2022 · The nucleus accumbens receives dopaminergic innervation from the ventral tegmental area (VTA) in the brainstem, glutaminergic from the prefrontal cortex (PFC) and orexinergic innervation from the lateral hypothalamus (LH) 2. Function. The predominant role of the nucleus accumbens is to influence planning and aversion based on pleasurable stimuli.
Oct 18, 2021 · The nucleus accumbens (NAc) plays an important role in regulating multiple behaviors, and its dysfunction has been linked to many neural disorders. ... Other MSN subtypes are located largely ...
