Our team consists of Ally, Isa, Sarahi and Brenda, abbreviated, this makes our team name “BISA.” Together in our biomedical class we are researching the functions and processes of a specific part of the brain. Our groups specific brain part is the Frontal Lobe. We are also looking up how this part of the brain can be affected by a TBI (or traumatic brain injury).
As growing teenagers, we sometimes don’t make the best decisions possible. Not because we are bad people overall, but because our frontal lobe is still developing. When the frontal lobe is developing, it is constantly affecting our decisions due to it maturing overtime.
The brain structure that we have chosen to study is the frontal lobe. The frontal lobe is located in the anterior part of the brain and posterior to your forehead. The frontal lobe makes up around 30% of the surface of the brain.
The key function of the frontal lobe is to control emotions and decisions. Your frontal lobes develops during your youth years and is fully developed around the age of 21 to 25, depending on gender. In this time decision making isn’t as strong. The frontal lobe is also involved in our consciousness and the way we perceive our surroundings or make judgements about them. It is in charge of movements and memory of habits. This may also be called “muscle memory.” We use the frontal lobe to give meaning with the words we use.
These functions are separated into subsections; motor, premotor and prefrontal regions. The motor cortex is the primary area of the brain that involved motor functions. The premotor also involves in the distinctive functional area as well. The prefrontal area is more divided into the subdivision and decision making of the brain. The frontal lobe is also split into two sections. The left portion of the frontal lobe controls functions involving language and the right controls emotions and functions related to social environments and judgement.
Any of these functions can be affected if the frontal lobe is injured. Victims of injury can have drastic personality changes, forget how to make decisions reasonably, how to do simple motions like walking, or have problems picking up on social cues and responding appropriately. Friends and family members have reported victims acting like a different person and having unrecognizable behaviours.
