Chronic food restriction potentiates behavioral and cellular responses to drugs of abuse and D-1 dopamine receptor agonists administered systemically or locally in the nucleus accumbens (NAc). However, the alterations in NAc synaptic transmission underlying these effects are incompletely Figure 2.

Stacy AW, Wiers RW (2010) Implicit cognition and addiction: a tool for explaining paradoxical behavior. Using brain imaging, researchers confirm that processed carbohydrates stimulate brain regions involved in reward and cravings, promoting food addiction."The brains pleasure center, called the nucleus accumbens, is essential for our survival as a species The nucleus accumbens (NAc or NAcc), also known as the accumbens nucleus or as the nucleus accumbens septi (Latin for nucleus adjacent to the septum) is a region in the basal forebrain rostral to the preoptic area of the hypothalamus. The nucleus accumbens, being one part of the reward system, plays an important role in processing rewarding stimuli, reinforcing stimuli (e.g food and water), and those which are both rewarding and reinforcing ( addictive drugs, sex, and exercise).[4][40] The nucleus accumbens, being one part of the reward system, plays an important role in processing rewarding stimuli, reinforcing stimuli (e.g food and water), and those which are both rewarding and reinforcing ( addictive drugs, sex, and exercise).[4][44] Thus, although they inform us regarding some cognitive factors in addiction and nucleus accumbens function, our animal models may inform us minimally about cognitive factors that are of major significance in humans. The nucleus accumbens, being one part of the reward system, plays an important role in processing rewarding stimuli, reinforcing stimuli (e.g food and water), and those which are both rewarding and reinforcing ( addictive drugs, sex, and exercise).[4][40] The nucleus accumbens (NAcc), also known as the accumbens nucleus or as the nucleus accumbens septi (Latin for nucleus leaning against the septum), is a collection of neurons located where the head of the caudate and the anterior portion of the putamen meet just lateral to the septum The nucleus accumbens, being one part of the reward system, plays an important role in processing rewarding stimuli, reinforcing stimuli (e.g food and water), and those which are both rewarding and reinforcing ( addictive drugs, sex, and exercise).

[4][44]in this book I read, Your Brain is Almost Perfect the author talks about drug addiction in this expectancy/reward model where when a person takes a drug, there is a certain reward in terms of dopamine associated in the various parts of the brain, especially the Nucleus Accumbens. Although the nucleus accumbens has traditionally been studied for its role in addiction, it plays an equal role in processing many rewards such as food and sex. Mesencephalic dopamine neurons form synapses with acetylcholine (ACh)-containing interneurons in the nucleus accumbens (NAcc).Here we examined the impact of local changes in muscarinic receptor activation within the NAcc on cocaine and food self-administration in rats trained on a Смотреть что такое "nucleus accumbens" в других словаряхnucleus accumbens — noun a) A dopaminergic nucleus found near the most anterior portion of the caudate nucleus. b) The primary nucleus thought to be involved with addiction Nucleus Accumbens. 15 April 2016 .

Damage to this region of the brain causes a lack of motivationWhen the cerebrum processes something that merits a reward — such as a favorite food or a narcotic — the NA releases dopamine and serotonin.
