"Dopaminergic pathways in the brain influence (1) reward processes (i.e., wanting and liking, and the reinforcement of pleasure behaviors), (2) executive functions (i.e., goal-directed behaviors, cognitive flexibility, and problem solving), (3) associative learning (i.e., acquiring and modifying behaviors, skills, etc.), and (4) motor control (i.e., coordination and control of reflexes and

This acts as a kind of lubricant for movement. With the loss of dopamine neurons in Parkinson’s disease, however, there is an increased amount of activity in the indirect pathway. Each pathway has its own associated cognitive and motor (movement) processes. Three of these pathways—the mesocortical, mesolimbic, and nigrostriatal pathways—are considered our “reward pathways” and have been shown to be dysfunctional in most cases of addiction.

Several transcription mesocorticolimbic dopamine pathways are involved in the cortisol may play a role in drug reinforcement through its interactions with the dopaminergic reward. Green arrows refer to excitatory glutamatergic pathways, red arrows refer to refer to dopaminergic pathways that are excitatory on the direct pathway and The image shows dopaminergic pathways of the human brain in normal condition (left) and Parkinsons Disease (right). Red Arrows indicate suppression of the The early development of dopaminergic pathways has been attributed importance and maturation of dopamine neurons, including LMX1A, LMX1B and PITX3.

Dopaminergic pathways apart from having a major role in the regulation of appetite and feeding behaviors are important immunoregulators in inflammation; thus, dopaminergic regulation is suggested to impact obesity- associated inflammation. Dopamine (DA) has been reported to modulate immune function and immune cells themselves produce endogenous DA. The neurons of the dopaminergic pathways have axons which run the entire length of the pathway. The neuron's soma produces the dopamine, which is then transmitted via the projecting axons to their synaptic destinations.
