The surge of joy that a person feels after receiving a positive evaluation, winning the lottery, or meeting a loved one is due to complex chemical processes in the brain. We can experience a huge number of emotions, such as sadness, grief, anxiety, fear, amazement, disgust, ecstasy, tenderness. These are neural connections.
When a person does something, learns something, new connections arise.
When repeating the same action, stable patterns of neurons are formed, which are responsible for what is called skill. And then a person is given what he does - very easily compared to other people.
