With reference to the adolescent brain, the maturation or growth of the frontal lobe (i.e. prefrontal cortex), comes after or is slower than the development of the limbic system.
The frontal lobe consists of the prefrontal cortex, premotor cortex, and the motor cortex. The prefrontal cortex is responsible for cognitive analysis, reasoning, anticipation, planning, problem solving, and impulse control. Its development lags behind the limbic system, which is responsible for emotions, behavior, motivation, long-term memory, and olfaction (sense of smell).
Because of this inequality in the development rate, together with the surge of adolescent hormones, teenagers tend to be more impulsive, rash, and emotional as the their "emotional side" develops more rapidly than their "rational, judging" side.
A method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.

Explanation:
The Pike Expedition (1806-1817) was a military expedition sent by the United States government to explore the recently acquired territory of Louisiana.
In 1803, French emperor Napoleon Bonaparte sold the territory of Louisiana to the United States. This territory was largely unexplored and populated mostly by indigenous tribes. Then president Thomas Jefferson authorized an expedition in 1806 to explore the south and west of the territory, close to the northern border of what was then New Spain (later Mexico). Lt. Zebulon Pike departed with 70 other men on his way to explore the Great Plains and the Rocky Mountains. However, he drifted south, and ended in Spanish territory, where he was captured. He was released shortly after and returned to the United States.
<u>In 1810, Pike wrote a book recounting from his memory his expeditionary exploits.</u> The book was immensely popular - it was later translated into French, German and Dutch.
