, its full maturity is only reached when a person is 25 or 26 years of age or when the myelin sheaths already made strong connections among the neurons in that section. The late full development of prefrontal cortex is due to the fact that brain’s development starts from back to front and from inner to outer.
Prefrontal cortex is the seat of affect regulation. It is this part of the brain that inhibits the function of the limbic system, the opposite of prefrontal cortex. While prefrontal cortex encourages good judgment and decisions not merely based on emotions, limbic system influences individuals to express emotions through overt behaviors. It is the part that is accountable to the fight-flight, and freeze behavior.
In the presence of the limbic system, prefrontal cortex acts as a buffer to the emotions that the former heightens. Since limbic system is at the bottommost part, it is noted to be the first part of the brain to develop (Wisegeek, 2014). Thus, it can be assumed that this is the reason behind children’s frequent tantrums and psychological problems.
Since the function of prefrontal cortex is hardly evident during infancy, this well-explains why the 4-year old Javier’s behavior is somewhat impulsive and violent especially towards his peers. The weak connections among the myelin sheaths of his prefrontal cortex(Bell &Mcbride, 2010) is also the reason why he cannot decide on what he wants and often do things that are peculiar such as opening the front door of the third floor and wandering on the ground floor of his family’s apartment.
Javier is a child of Isabel who is married to her husband for already five years. Isabel’s marriage is a bit problematic because tension arises between them whenever her husband got home drunk. At an early age, Javier is a witness to a bitter marriage and thus, poor emotional security which is also needed to enhance the development of the prefrontal cortex. The emotions, especially the fear or horror that Javier
