Neural Circuits in the Brain ‘Sense’ Our Inner State

In order to be able to make such evaluations, we need signals in the brain that tell us “This is good” or “This is bad.” The dopaminergic system in the brain, better known as the reward system, plays an important role in these evaluations. Understanding what happens in the brain. Neurons that produce dopamine, known as dopaminergic neurons, play a role in a range of diseases, from addictive behavior and obesity to Parkinson’s disease. In addiction or obesity, the reward system signals can be too strong or also too weak. In Parkinson’s disease, dopaminergic neurons degenerate, and this affects the control of motor functions. ….[READ]
