Brain


Certain parts of the brain govern specific functions such as sensory and motor, in addition to the cerebellum for coordination and to the hippocampus for memory. The nerve cells, or neurons, connect one area to another via pathways to send and integrate information. The distances that neurons extend can be short or long, such as the reward pathway which is activated when a person receives positive reinforcement for certain behaviors or drugs (“reward”). Since Humans, as well as other organisms, engage in behaviors that are rewarding, the pleasurable feelings provide positive reinforcement so that the behavior is repeated. There are natural rewards as well as artificial rewards. 

Effect of drugs on brain functions:

Impact in general:

• Rush guidance is limited to drugs at the expense of other things.

• The expectation of the result of the material is greater than its direct feeling.

• Increases dependency and stamina when under heroin addiction.

• Control zone activity is reduced.

• Logical brain growth is impaired.

• The function of collecting and linking information is disrupted.

• The activity of the brain is disturbed instinctively by sleep system disruption and heart beat dysfunction and breathing arrest, leading to death.

Particular influence: the functions involved and which are affected in case of addiction:

• Influence on control ability:

O Loss of control to make the right decisions and therefore to live freely, making us a victim of slavery of narcotics.
