Juveniles do not have the reasoning ability that adults do. Their brain is immature. The brain contains about one-hundred million neurons. Neurons do not touch, but transfer information through electrical charges within the brain by chemicals called neurotransmitters. Between each neuron is a small space called a synapse. By the age of two a single neuron may have ten thousand synapses connecting to other neurons. As an individual ages, the brain eliminates unused and unnecessary synapses through a process called synaptic pruning. As this process occurs, the brain changes. At any given age the greatest developmental change takes place in the same region of the brain as the one being trimmed (Steinberg).
In adolescence the frontal cortex is being trimmed. This is the area of the brain associated with reasoning, planning, and judgment (Ruder). Unlike adults, adolescents focus on the immediate rewards a situation brings (Brown). In teens, dopamine levels are higher than at any other stage in life. This, as well as an undeveloped frontal cortex, cause the inherent search for thrill and disregard of consequence. The search for pleasurable experiences lessen a teen’s ability to control impulses making them
