Defining a role for the peduncolopontine tegmental nucleus in striatal outflow [PDF]
, 2012 The pedunculopontine tegmental nucleus (PPTg) lies within the pontomesencephalon and contains cholinergic and non-cholinergic neurones. It has extensive afferent and efferent connections throughout the brain.

Functional bias of morphine and oliceridine under conditions of minor injury
Molecular Pain, 2021 Recent reports suggest pain from surgical injury may influence the risks associated with exposure to opioids. In mice, hind-paw incision attenuates morphine-primed reinstatement due to kappa opioid receptor activation by dynorphin.

The bivalent side of the nucleus accumbens [PDF]
NeuroImage, 2009 An increasing body of evidence suggests that the nucleus accumbens (NAcc) is engaged in both incentive reward processes and in adaptive responses to conditioned and unconditioned aversive stimuli. Yet, it has been argued that NAcc activation to aversive stimuli may be a consequence of the rewarding effects of their termination, i.e., relief. To address

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021 Abstract Introduction Deep brain stimulation (DBS) is an effective treatment for refractory obsessive–compulsive disorder (OCD). Neuropsychological assessment contributes to DBS treatment in several ways: it monitors the cognitive safety of the treatment, identifies beneficial or detrimental cognitive side effects and it could aid to explain ...

The Nucleus Accumbens: A Comprehensive Review [PDF]
Stereotactic and Functional Neurosurgery, 2015 There is increasing interest among functional neurosurgeons in the potential for novel therapies to impact upon diseases beyond movement disorders and pain. A target of increasing interest is the nucleus accumbens (NAc), which has long been studied as a key brain region mediating a variety of behaviors, including reward and satisfaction. As such, focal

Nature Communications, 2018 The nucleus accumbens regulates many behaviours that depend on arousal. Here the authors show that dopamine D1 receptor neurons in the nucleus accumbens can directly regulate wakefulness.

Lithium treatment impacts nucleus accumbens shape in bipolar disorder
NeuroImage: Clinical, 2020 The effects of lithium treatment duration on deep grey matter structures in bipolar disorder are not well known. In this cross-sectional neuroimaging case-control study, we tested the hypothesis that shape characteristics of deep grey matter structures ...

Effects of hippocampal damage on reward threshold and response rate during self-stimulation of the ventral tegmental area in the rat [PDF]
, 1999 The main purpose of this study was to explore the role of the hippocampus in motivated behavior. Rats with bilateral excitotoxic lesions of the hippocampus and controls were trained to lever press for electrical stimulation of the ventral tegmental area.

Gustatory reward and the nucleus accumbens [PDF]
Physiology & Behavior, 2006 The concept of reward is central to psychology, but remains a cipher for neuroscience. Considerable evidence implicates dopamine in the process of reward and much of the data derives from the nucleus accumbens. Gustatory stimuli are widely used for animal studies of reward, but the connections between the taste and reward systems are unknown.
