Nucleus Accumbens and Dopamine-Mediated Turning Behavior of the Rat: Role of Accumbal Non-dopaminergic Receptors

Journal of Pharmacological Sciences, 2012
Accumbal dopamine plays an important role in physiological responses and diseases such as schizophrenia, Parkinson’s disease, and depression. Since the nucleus accumbens contains different neurotransmitters, it is important to know how they interact with

The dopaminergic midbrain participates in human episodic memory formation: Evidence from genetic imaging [PDF]

, 2006
Recent data from animal studies raise the possibility that dopaminergic neuromodulation promotes the encoding of novel stimuli. We investigated a possible role for the dopaminergic midbrain in human episodic memory by measuring how polymorphisms in ...

Specialized coding of sensory, motor, and cognitive variables in VTA dopamine neurons

Nature, 2019
There is increased appreciation that dopamine neurons in the midbrain respond not only to reward1 and reward-predicting cues1,2, but also to other variables such as the distance to reward3, movements4–9 and behavioural choices10,11. An important question

Testosterone induces molecular changes in dopamine signaling pathway molecules in the adolescent male rat nigrostriatal pathway. [PDF]

PLoS ONE, 2014
Adolescent males have an increased risk of developing schizophrenia, implicating testosterone in the precipitation of dopamine-related psychopathology.

Corticosterone Acts in the Nucleus Accumbens to Enhance Dopamine Signaling and Potentiate Reinstatement of Cocaine Seeking [PDF]

, 2013
Stressful life events are important contributors to relapse in recovering cocaine addicts, but the mechanisms by which they influence motivational systems are poorly understood.

Dopamine-modulated dynamic cell assemblies generated by the GABAergic striatal microcircuit [PDF]

, 2009
The striatum, the principal input structure of the basal ganglia, is crucial to both motor control and learning. It receives convergent input from all over the neocortex, hippocampal formation, amygdala and thalamus, and is the primary recipient of ...

Conformation of dopamine at the dopamine receptor. [PDF]

Proceedings of the National Academy of Sciences, 1978
Tritiated dopamine was used to label the dopamine receptor in membranes isolated from the rat corpus striatum. Scatchard analysis of displacement of [3H]dopamine by nonradioactive dopamine indicated the presence of two binding sites. The similarities in affinity, capacity, and drug specificity of the high-affinity site in the striatal membranes from ...

Dopamine D1 and D2 receptor immunoreactivities in the arcuate-median eminence complex and their link to the tubero-infundibular dopamine neurons

European Journal of Histochemistry, 2014
Dopamine D1 and D2 receptor immunohistochemistry and Golgi techniques were used to study the structure of the adult rat arcuate-median eminence complex, and determine the distribution of the dopamine D1 and D2 receptor immunoreactivities therein ...

The Dopaminergic Midbrain Encodes the Expected Certainty about Desired Outcomes [PDF]

, 2014
Dopamine plays a key role in learning; however, its exact function in decision making and choice remains unclear. Recently, we proposed a generic model based on active (Bayesian) inference wherein dopamine encodes the precision of beliefs about optimal ...
