The biological theory of agression claims that agression is caused by the biological factrs of a person, and so states that we can reduce how agressive a person is by altering their biology.
This is often done through drugs, such as Ritalin, which is used for people with ADHD to reduce the agression formed in the brain. The drug stimulates activity in the brain and has been found to be effective at reducing agressive behaviour thats caused by ADHD. Ritalin stimulates the pefrontal cortex, and helps to control the agressive instincts caused by the limbic system.
An alternative method of reducing agression biologically is through psychosurgery, which involves either removing or destroying parts of the brain that aren't working as they should. Research has shown that its usually the limbic system that is responsible for causing agresssive behaviour, and so its usually the limbic system thats removed. Psychosurgery isn't used often because it puts patients at high risk of permanent brain damage.
