帕金森病是其中最著名的一种,影响大约2%的人口,它是由黑质(substantia nigra)或黑质纹状体通路(nigrostriatal pathway)的神经元死亡引起,可导致运动障碍,例如颤抖、僵硬、缓慢和行走困难。舞蹈症和成瘾也与黑质纹状体通路有关。 精神分裂症与中皮层和中脑缘投射有关;特别地,中皮层通路对应病理的阳性症状,中脑缘通路对...
Moreover, music enhances the effect of alcohol in mice. These findings suggest that music leads to increased calcium/CaM-dependent DA synthesis in the brain, and that music containing high-frequency sounds stimulates this pathway, and might thereby regulate and/or affect various brain functions, ...
in reward-related behavior as well as other higher cognitive functions such as memory and goal maintenance. Dysregulation in the mesolimbic pathway and mesocortical pathway has been implicated in pathological conditions such asschizophreniaand addiction. Due to its importance, the midbraindopaminergicsystem...
A completed run, the early morning hit of caffeine, the smell of cookies in the oven — these rewarding moments are all due to a hit of theneurotransmitterdopamine, released by neurons in a neural network in our brain, called the “dopaminergic reward pathway.” Apart from mediating the fee...
[194,195]. Other studies support the central role of the canonical pathway in the patterning of the MHB region, where the direct inactivation of β-catenin in a specific manner in the MHB mimics theWnt1mutant phenotype [170,196]. Furthermore, mutant mice for the Wnt receptor Lrp6 also ...
The mesolimbic pathway: It transmits dopamine from the ventral tegmental area (VTA, located in the midbrain) to the ventral striatum, bed nucleus of the stria terminalis, hippocampus, and septum. This pathway contributes to both reward- and aversion-related cognition, positive reinforcement, incenti...

Dopamine has a significant role in motor and cognitive function. The dopaminergic pathways originating from the midbrain have received the most attention; however, the relevance of the cerebellar dopaminergic system is largely undiscovered. Here, we show that the major cerebellar astrocyte type Bergmann...
(VTA) in the midbrain. Projections from SNc to the striatum (STR) form the nigrostriatal pathway that is important for controlling voluntary movement. Projections from VTA to the nucleus accumbens (NAc) and the frontal cortex make up the mesocorticolimbic pathway to regulate memory, reward, ...
The mesolimbic dopaminergic pathway is the major reward pathway of the brain. As a result, dysfunctions in the dopaminergic systems are involved in several pathological conditions including Parkinson’s disease, Tourette’s syndrome, drug addiction, and hyperactivity disorders. Dopamine binds to two fami...
