Cerebral cortex

brain to treat a personality disorder, behavior disorder, or other mental illness. Modern psychosurgical techniques target the pathways between the limbic system (the portion of the brain on the inner edge of the cerebral cortex) that is believed to regulate emotions, and the frontal cortex, where thought processes are seated. Psychosurgery is a general name for any surgery that is performed on the cerebrum to reduce dysfunctional behavior. Psychosurgery for the most part includes decimation of…

cortical sizes and amount of gray matter. Cortical size formation is correlated with number of cortical divisions. Signaling molecules, called patterning centers, determine what kind of neuron the neuron will be before it is sent out to its subsequent cortex to form synapses. Building off previous cortical organization theories, Dr. Buckner and Dr. Krienen came up with the tether…

are some people who have Posttraumatic stress disorder are in denial. PTSD can reduce the use of the amygdala due to the deep brain stimulation (Langevin et.al., 2016).The deep brain stimulation can inadequate the control of a cerebral target from the medial prefrontal cortex (Langevin et.al., 2016). Posttraumatic stress disorder is more common to be found in women than men (Bangasser, Wiersielis, & Khantsis, 2016). People who have Posttraumatic stress disorder have flashbacks and not always in…

1. Neurogenesis and memory 1.1. Neurogenesis in the hippocampus The hippocampus is a brain region that responsible for learning, memory and mood. One of the important reasons for memory and mood dysfunction is the dentate gyrus (DG) reduction [12, 13]. The subventricular zone (SVZ) and the subgranular zone (SGZ) of neural progenitor cells generated neurons and glia in adulthood and during adulthood [14]. Neurogenesis also have a role in mood regulation; the dorsal hippocampus is an…

Crib Tunes May Have Made You Smarter Music is an integral part of culture, economy, society, and, not surprisingly, our development. Different musical notes condition their brains to different sounds in the environment. Furthermore, musical complexities may subconsciously work their way into the calculating capacity of the child’s cognition and inspire toward a higher level of thinking at a younger age, ultimately influencing the behavior of the adult brain. Studies that try to delineate…

As previously learned in class, the definition of evolution is the change in variant frequencies in a population over time. The four forces that evolution acts on are mutations, gene flow, genetic drift, and natural selection. From an evolutionary psychology perspective, the physical structure of the brain has changed over time, thus allowing humans to develop complex behavioral patterns. When comparing brains with primates, humans have a larger and heavier brain. When compared to a…

This essay discusses the misconception about the percentage of the brain we use at any given time. Despite there is no scientific evidence the commonly held notion is that humans only use ten percent of their brains is the most common among neuromyths. The lesser know reality is that we have access to our full brain potential. Throughout human history, rumors and exaggerated stories spread like wildfire. They seem to be related to human fears, and the collective effort to ménage them. The…

seizures. Studies have shown that 23 out of 29 seizures have significantly reduced the possibility of having an episode just by listening to piano masterpieces like Mozart. It is due to the melodic, calming tones of the piano affecting the cerebral cortex. This study was done back in 1998 and published in the experiment “Mozart Effect on Epileptiform Activity." For those who are ill-fated with this tragic physical exhibition, always keep a backup CD of piano songs nearby just in case there…

processes that increase the risk of adverse side effects of alcohol on one. In other words, main areas in the brain are under construction and are more sensitive to the toxic effects of alcohol. These effects inhibit parts of the brain such as the cerebral cortex, central nervous stem, frontal lobes, hippocampus, cerebellum, hypothalamus, and medulla. In more detail, it makes one…

1. There is an increasing amount of elderly rising in today’s society. According to the U.S census bureau, and the 2010 census taken, the elderly percentage in America is steadily on the rise, due to the baby boomers (Ortman, Velkoff, & Hogan, 2014). In 2010, the elderly population made up approximately 13% of the entire U.S population, in one decade, the number of adults 65 and older, increased by six million people (Werner, 2011). According to this census, a group of analysts were able to…
