Frontal Lobe
The frontal lobe, also known as the emotional control center, is the principal lobe of the brain which gives each individual his or her own personality and behavioral characteristics. Located in the anterior segment of the cerebral cortex, the frontal lobe consists of three primary regions, all of which have their own significant functions and controls (Bailey, 1). First, the prefrontal cortex, which determines the unique persona of each individual along with elaborate cognitive behaviors as well (Bailey, 1). Alongside the prefrontal cortex are the premotor and motor areas. These regions are made up of nerves which execute voluntary muscle movement (Bailey, 1). Together, the regions of the frontal lobe have several other functions such as memory, language, impulse control, sexual and social behavior, spatial orientation and problem solving (Espay, 2). However, a small problem with this highly important and primary brain piece is its vulnerability to injury.

Located at the front of the head, the frontal lobe is immediately placed in a high risk place for impact. Not only is it the most common region of injury, but it’s also a dangerous section to damage due to the risk of leading to rather specific clinical syndromes (Espay, 2). Once dysfunction of the frontal lobe is detected, a thorough examination is necessary. Trauma to the frontal lobe has been discovered to cause a loss of interest in sexual behavior along with significant changes in social behavior as well (Niedermeyer, 1). Since symptoms of frontal lobe damage are changes in personality and behavior, the damage is often easily detectable however, careful test methods are needed in order to probe and analyze the damage done due to the frontal lobes large size and routine non-specified evaluations (Espay, 1). A few specic illnesses of the frontal lobe are schizophrenia, attention deficit disorder and antisocial personality disorder(Niedermeyer, 1).
