  • Self Awareness Research Paper

    neurologists focused on what was believed to be the disproportionally larger prefrontal cortex (PFC) in humans compared to apes and other primates. More recently, research focuses on specific areas within the PFC that are size-dysmorphic in humans and apes. One study examined the male brains of 19 primate species (including humans) for relative size changes of cell tissue in the anterior and posterior axes of the frontal lobe in both hemispheres. The results of the study found that the primary factor in the difference between humans, great apes, and lower primates is not an overall size-dimorphism of the PFC as early research believed, but rather, is a larger left hemisphere of the PFC. Evolutionally lower primates have a larger size difference between left and right hemispheres of the PFC. The size difference between the left and right hemispheres is the smallest in human brains. Additionally, humans have significantly more white matter in the left PFC than non-human primates. These size differences in the left PFC between humans and apes may play a part in metacognitive abilities such as introspection and self-awareness (Smaers, Steele, Case, Cowper, Amunts, & Zilles, 2011). Three Important Brain Regions Researchers mainly focus on three specific brain regions that seems to be important for self-awareness: the anterior insular cortex (AIC), the anterior cingulate cortex (ACC), and the medial prefrontal cortex (mPFC). The AIC contributes to self-awareness in a number of…

  • Abortion In Unwind, By Helen Neal Shusterman

    novel, Connor Lassiter, Risa Ward, and Levi Calder all go through their own journeys with unwinding meeting all kinds of people along the way. Neal Shusterman’s, Unwind, proves that Unwinding is an absurd and unreasonable answer to abortion because it interrupts the brain development, allows no room for failure, and gives parents a wrong way of dealing with troubled teens. Shusterman’s concept of unwinding does not give teenagers a chance to have a fully developed brain. On National Public…

  • Three Second Memory Essay

    325). Researchers believe that humans have a more advanced cognitive ability because of a “six-layered neocortex” (Brown, 2011, p. 325). Fish were believed to have a small paleocortex in their forebrain, therefore, structures such as the hippocampus, which is responsible for memory, the cerebral cortex, responsible for processing information, and the amygdala, which is responsible for conditioned learning would not be present in the telencephalon (Hines, 2016 April). However, recent studies have…

  • Stress

    respiratory system, stress can make you breathe harder and cause rapid breathing or hyperventilation which can bring on panic attacks in some people. Following, is the Diaz5 cardiovascular system, acute stress, stress that is momentary, such as being stuck in traffic caused an increase in heart rate and stronger contractions of the heart muscle.

  • Anterior 2/3 Term Paper

    3. A. Cranial nerve involvement can be broken down into two portions. The anterior 2/3 of the tongue are innervated by the Chorda Tympani branch of the Facial nerve which is carried by the lingual nerve which branches off the mandibular branch of the Trigeminal nerve. Sensory component of the anterior 2/3 is maintained by the lingual nerve. The posterior 1/3 of the tongue is innervated by the glossopharyngeal nerve which supplies both sensory and taste. B. The human tongue contains multiple…

    couple of hours a day recovered faster (The Effect Music Has On The Brain). In particular the patients seemed to have better verbal memory and attention span (The Effect Music Has On The Brain). Due to the improved memory and attention span, it becomes obvious that music has fantastic healing characteristics. An amazing piece of research from 1998 says that music can get rid of seizures once and for all (The Effect Music Has On The Brain). In order to reduce the signals that cause a seizure ,…

  • A Comfort Zone Analysis

    The mind is one of the most powerful weapons on earth. "We are shaped by our thoughts; we become what we think." It has the ability to push you forward or hold you back.

For the greater part of my life, I stuck with…

  • Brain Scans And Depression

    The human brain is complex. No matter how much scientists study it, there always seems to be more to learn about the human brain. Sometimes it seems the more we learn about the brain, the more we realize just how much we still do not understand. While this is by no means a complete explanation of everything going on neuroscience, here are three recent medical studies connected with the brain: Brain Scans and Depression Recently, researchers at King’s College London and The University of…
