Prefrontal cortex
Explanation:
Prefrontal cortex: It covers the front part of the cerebral cortex and is found in the frontal lobe in the brain. The prefrontal cortex is responsible for various complex behaviors, for example, personality expression, complex cognitive behavior, decision making, personality development, conducting social behavior, and planning, etc.
The prefrontal cortex of a human brain is one of the last parts of the brain structure to develop. A human prefrontal cortex completely develops at the age of twenty-five years. Due to this factor, the functionality of a teenager and an adult is different. The prefrontal cortex is considered to be the brain's rational part.
It is responsible for leading executive functions such as attention, problem-solving, and memory. It plays an important role in the development of short-term memory.
In the question above, during adolescence, the prefrontal cortex is biologically immature and its ability to inhibit impulses is not fully developed, because the prefrontal cortex completely developed at the age of twenty-five and hence the functionality related to the cortex.
