Prefrontal Cortex In The Brain

The frontal lobe is located at the front of the brain and is associated with reasoning, motor skills, higher level cognition, and expressive language.

Creating the world's first Z-Bomb, would have to be the most dangerous thing that could happen to humans. Turning them into Zombies, it would entirely change the characteristics of a human being and its brain. Although both living, Zombies have drastic defects towards certain aspects of the body. This Z-bomb won’t necessarily turn humans into zombies, but rather give humans zombie-ish characteristics.

Two brain structures that could likely be affected by this damage are the frontal lobes and the temporal lobes. The frontal lobe produces speech, controls motor skills, and initiates leading functions such as thinking, personality, emotion and memory. (Huffman, K., Dowdell, K. 2015. Pg. 71). The temporal makes it possible for an individual to hear properly, comprehend language, recollect thoughts, and maintain emotional stability; this lobe also contains the auditory complex, which is responsible for the interpretation

67) The frontal lobes are described as the brain’s “orchestra leader” (Martin, 1998, p. 190), which would place them at the reins of controlling effective behaviour. Damage to the frontal lobes encompasses a wide range of symptoms including deficits in executive functioning, changes in personality, emotional expression and social interaction. This includes apathy and lack of spontaneity, inability to plan and modify the sequencing of behaviour and inappropriate behaviour. 2

The prefrontal cortex is the brain region that controls responsible decision-making. However, “[p]rior to adolescence, the [prefrontal cortex] isn’t quite advanced enough to guide all the other brain regions. That’s because it still doesn’t know the rules of the game. ‘So that’s why you have parents to act as your prefrontal cortex’” (Mascarelli).

Recent research has shown that the human brain continues to develop throughout childhood and adolescence, and may not be fully mature until the mid-20s. The prefrontal cortex of the brain, which regulates “executive” functioning skills, such as decision-making, planning, judgment, expression of emotions, and impulse control, is one of the last to

The brain's white matter, prefrontal cortext responds to judgment and impulse control is different in adolescent than adult. During adolescent, teenagers can easily be more frustrated and upset for no reason, while the adult are calmer with the emotion. This also true because when I was in my teenage years, if things wasn't going according to what I want, I would be upset with everything around me.

Lesions of the Prefrontal Cortex The prefrontal cortex is involved in a wide variety of functions. It is known as the area of the brain which has “executive control”, taking input from other areas of the brain and combining and applying those functions (Kalat 2004). Lesions to the prefrontal area can greatly impair overt behavior of an inflicted individual. These deficits are dependent upon the severity of the lesion and the specific region of the prefrontal cortex in which the lesion resides (ventrolateral, dorsolateral, orbitofrontal, and anterior prefrontal)(Eslinger 2003).

The prefrontal cortex plays a major key role in Neurocognitive Networks of impulsivity and transition to addiction. The cortex regulates the reward and its involvement in higher-order executive functions, such as self-control, goal oriented behavior, and response inhibition. According to “Goldstein and Volkow” reviewed neuroimaging data of specific prefrontal cortex regions and their roles in neuropsychological mechanisms that underlie the relapsing cycle of addiction. Focusing on inhibitory control and emotion regulation, there are two different prefrontal regions, which are implicated in a higher order cognitive process (cold), and ventral PFC regions subsuming the ventral OFC, ventromedial PFC and rostroventral ACC, which are triggered during

This part of your brain isn’t “fully developed until you are around 25 years old. Your Frontal Cortex affects things such as “attention, complex planning, decision making, impulse control, logical and organized thinking, risk management, ands short term memory (Mental Health Daily).” If the part of our brain that is responsible for taking care of those

The dorsolateral prefrontal cortex is largely responsible for formulating literacy along with reasoning processes, widely coined as the ‘conscious’ segment of the frontal lobe. Spontaneous, creative ideas originate this the large portion of the brain, of which was thought to evolved as a mechanism for a nonchalant, supercilious resolution for solving complex conflicts. Asides from humans, many organisms, ranging from ant’s pheromone communication evolution to a protozoans use of new amino acids have shown that this innovating solution is considerably repetitive in nature. Throughout millions of years, archaic humans gradually evolved creativity to confiscate for the lack of physical dominance, bestowing them with the ability to form civilizations.

The prelimbic cortex (PL) is an important structure involved in several stress-related functional processes, such as cardiovascular, hormonal and behavior responses. Since there is an increased expression of central angiotensinergic receptors during stressful situations, we tested the hypothesis that such angiotensinergic neurotransmission in the PL modulates the autonomic responses evoked by restraint stress in rats, such as blood pressure and heart rate increases, and reduction in tail temperature.. Male Wistar rats were used and guide cannulas were bilaterally implanted in PL for microinjection of vehicle or drugs. A polyethylene catheter was introduced into the femoral artery for recording of cardiovascular parameters using a computerized

The prefrontal cortex could be divided into different anatomical regions depending on different criteria, but the most widely accepted division is based on anatomical connectivity and functional specialization, is between the dorsolateral and ventromedial sectors. The dlPFC includes portions of the superior and middle frontal gyri on the lateral surface of the frontal lobes, and receives input from specific sensory cortices, and has dense interconnections with premotor areas, the frontal eye fields, and lateral parietal cortex. This special pattern of connectivity suggests various functionality. Scientists believed that dlPFC has primarily been associated with “cognitive” or “executive” functions. Unlike the other part (vmPFC- ventromedial

EF is made up of a set of cognitive control methods and is mostly, supported by the prefrontal cortex (PFC). The PFC regulates lower level processes (e.g. perception and motor responses) supporting self-regulation and self-directed behavior toward a goal. This allows us to evaluate risks and make decisions, plan for the future, sequence and prioritize our actions and cope with new situations. Individual characteristics in EF are associated with many important aspects of human health and functioning, including academic and occupational functioning, interpersonal problems, substance use, physical health, and mental health. EF impairments are related to most forms of psychopathology. Poor EF predicts rumination, worry and poor use of adaptive emotion regulation methods; all potent risk factors for multiple forms of psychopathology (Snyder, Miyake, and Hankin,
