substance-related disorders, we may say they target mainly the reward system

Speaking about substance-related disorders, we may say they target mainly the reward system. I want to remark this structure’s strange name from the natural sciences’ viewpoint. However, the reward system is described neurobiologically with the help of chemical and physiological process of the brain. Dopamine, serotonin and other substances, which are referred to in the biochemical analysis of the reward system don’t associate with fanfares, awards and other means of human reward for his or her contribution to this or that community. In our minds the chemistry just doesn’t seem quite in line with such things as fame, recognition and even the pleasure of resting on laurels, perceptible by many. Well, why not the pleasure? Many have experienced it. However, it can be experienced, but can’t be described by words. To speak a bit figuratively we can describe the reward system as a trace of God in the human mind. But again, the specific feature of this structure is that it lays in so-called ancient layers of the brain inherited by humans from their biological ancestors. It’s quite tricky: all human’s higher nervous activity all human’s social achievements and losses can be explained by the processes in the depths of the brain that appeared long before anything anthropic we’ve now began to exist. We’ll make a simple example from everyday life. Just imagine how long is the way from external social activities through the thinking processes and the bitterness of doubts and disappointments to a simple chemical reaction that tells me, job well done, go, have a rest. Alcohol and other drugs are chemical substances that bypass a hard rational way to reward system liberating a human from a burden of serving the society.
