The Human Brain Is An Interesting Artifact

Fearful situations make the brain release chemicals like dopamine, adrenaline, and endorphins. In Allegra Ringo’s “Why Do Some Brains Enjoy Fear?”, an interview with Dr. Margee Kerr, who earned her PhD in sociology at The University of Pittsburgh, and wrote Scream: Chilling Adventures in the Science of Fear, explaining the psychological process in

I started my education in Erie, Pennslyviana.I attend McDowell High. I would say that we were one of the richer schools were I live. I am going to talk about my first assignment Brainology. I thought it was very interesting and it thought me a lot about how some people have different mindsets.

When it comes to the topic of having a growth mindset, most of us will readily agree that students who are praised are motivated to learn. Where this agreement usually ends, however, is on the question of how they are praised. Whereas some are convinced that praising students for their intelligence will motivate them to learn, others maintain that encouraging them for their efforts has a better impact on their motivation.

While on patrol, I was parked in the entrance to Mansard's plaza, facing E Ridge Rd, monitoring traffic. A female in a silver pickup truck pulled into the lot and flagged me down. The female pointed towards a white and maroon Corvette traveling east on Ridge Rd and stated that she believes the driver may be intoxicated. I immediately pulled onto Ridge Rd and got behind the Corvette. As I was following the Corvette east on Ridge, another vehicle with a male driver pulled up to the side of me and shouted out the window, "That guy is drunk". I then observed the Corvette to weave from the outside lane to the center lane, without signaling. The vehicle then abruptly swerved back into the outside lane, without signaling. The vehicle then came to

Studying parts of the brain that are involved in dealing with fear and stress also helps researchers understand possible causes of PTSD to begin formulating a plan to treat PTSD. The amygdala is known for its role in emotion, learning, and memory. The amygdala appears active in learning to fear an event as well as in the early stages of fear extinction. In storing extinction memories and dampening an existing fear the prefrontal cortex, which is involved in problem solving, decision making, and judgement, is seemingly

Many scientists have been turning to genes that may have a role in creating fearful memories for an explanation as to what causes PTSD. They have also been studying different areas of the brain that control fear and stress such as the amygdala and prefrontal cortex. The amygdala has a role in the early stages of learning to fear and not to fear certain situations. The prefrontal cortex is said to help control the extinction of long term fearful memories. An individual genetics, brain area growth, and other environmental factors play a role in the risk of the individual developing PTSD after a traumatic

One of the greatest emotions that controls the way people act or think in certain ways is fear. Fear is an unpleasant emotion caused by the belief that someone or something is dangerous. Fear of the unknown is the most harmful

The distinction between conscious and unconscious memory suggests - and it is generally accepted - that emotional memory involves two brain systems. While conscious memory is mediated by the hippocampus, the amygdala is implicated in emotional memory (1). A small collection of nuclei in the center of each temporal lobe, the amygdala controls the fear response, receiving and integrating sensory input to determine the level of threat. If the input is sufficiently intense to initiate an action potential, the amygdala triggers other areas of the brain that induce the physiological response that humans interpret as fear (3); the danger has been "recognized."

What, teachers can change your answers on the tests, that means no more studying for me! What class is this and where do I sign up? The thought of teachers changing answers on a test doesn’t possible to happen; unfortunately, it actually occurred at Parks Middle school, when the teachers had changed the students answers on a standardized test. They were caught and had to face many consequences besides losing their jobs; it seems they can serve time in jail for the “criminal act” they did. The school was not doing well in the beginning, since they had low test scores for “the past 6 years in a row.” It may seem the teachers just lost hope towards their students of scoring well on the test, causing them to take matters in their own hands. The

Two structures in the brain work independently and with each other to impact memory and emotions: the amygdala and the hippocampus. The amygdala is linked to fear-conditioning, while the hippocampus is linked to episodic memories, which are those memories that a person can recall whenever wanted [1]. An experiment was performed to demonstrate the independence of the two structures from each other which involved patients with lesions in the amygdala and patients with lesions in the hippocampus. Researchers designed a fear-condition wherein a blue patch applied to the wrist initiated a shock. They found that patients with lesions in the amygdala had no physiological response to the conditioned stimulus (the blue patch) [2], whereas patients with lesions in the hippocampus demonstrated appropriate

The amygdala is the most widely researched in this case because of its role in emotion, learning, and memory. The amygdala appears to be active in fear acquisition, or learning to fear an event, as well as in the early stages of fear extinction, or learning not to fear (NIMH). Secondly, the prefrontal cortex also plays a part in the storage of memories and fear response. The prefrontal cortex is responsible for tasks such as decision-making, problem-solving, and judgement. For example, when it deems a source of stress controllable, the medial PFC suppresses the amygdala an alarm center deep in the brainstem and controls the stress response. The ventromedial PFC helps sustain long-term extinction of fearful memories, and the size of this brain area may affect its ability to do so

The limbic system was first recognized due to Franz Josef Gall (LeDoux, J., 1996). Franz Joseph Gall developed the idea of “phrenology” that focused on the study of the different variations of bumps on the human skull to be related to differences in behavioral and emotional functioning. The limbic system’s main function in the brain is to control emotional behaviors and certain forms of memories that are infused with emotion (amygdala). The amygdala is a part of the brain that forms the tail end of the basal ganglia within the rostral temporal lobe and is located near the hippocampus (Lambert, K.G. & Kinsley, C .H., 2005). The amygdala, as defined by the text, is an almond-shaped structure that functions as a part of the limbic system involved in regulation of emotion and sexual urges (Lambert, K.G. & Kinsley, C .H., 2005). In addition, the amygdala is comprised of a dozen or more sub regions that are not all involved in fear conditioning (LeDoux, J., 1996).

The importance of the amygdala in social cognitions has been examined in both primate and human studies. Use of primates to study the social brain suggests that the amygdala contributes to social cognition. Kluver and Bucy made large bilateral lesions in monkey brains made across the amygdala, temporal neocortex, and surrounding structure. After the lesion, the animals engaged in hypersexual behaviors, unusual tameness, and a lack of knowledge about emotional stimuli. Lesions exclusively targeting the monkey’s amygdala resulted in similar, but more subtle impairments. This suggest that the amygdala may play a role in emotions elicited by social cues. Studies of the amygdala’s role in human social cognition suggest that the temporal lobes process socially relevant facial information from humans. Emotions from facial expressions, in particular fear are projected to the amygdala. Studies using FMRI to examine typical subjects and subjects with amygdala damage support this theory. Individuals with amygdala damage have difficulty recognizing facial expressions, specifically negative emotions such as fear.

For those who don’t know, the brain is the most complex organ in the human body because of all the multiple sections that make up the brain. The human brain is found in the cranial cavity and is also a vital part of the nervous system. As a matter of fact, the reason why the brain is such a precious organ is because it allows us to interpret and store new information along with giving us the ability to move our body and enabling us to express ourselves.The brain can be broken up into three portions: the Forebrain, the Midbrain and the Hindbrain. These three potions regulate our body temperature, our breathing and heart rate as well as tell us when to eat and sleep. Therefore any severe damage to one of these portions could be life-threatening.

The brain is arranged and organised in layers with diverse levels of functioning. That our brain continues to grow across our life duration (O'Donnell et al, 2013, pp 97-100). Based on the findings of the statement that 1O percent of our brain it can be argued it is one big myth. Article in Scientific American Mind wrote that No matter what you’re doing, your brain is always active. Brain scans show that the activity of brain varies to each individual where more are active than others. However, no section of the healthy brain is solely turned off.
