Are Teens More Rational Than Adults? The human brain is a complex organ that serves as the center of the nervous system. It is made up of over 100 billion nerves that (with the cortex and other parts of the brain) help communicate throughout the body. By sending signals to different parts of your body, the brain communicates and is the main control centre.”Grey matter contains most of the brain's neurons, and it plays an important role in emotions, memory, decision-making, and…

Bats are associated with the phrase, “Guardians of the Night” yet have horrible eyesight in the evening. To navigate after dark, bats use echolocation. Echolocation is the act of using the reverberation of a sound transmitted out of the body to detect objects in the surrounding area. Scientist for many years believed animals only had this ability. Due to human brains tending to suppress the frequency of echoes. This capability to retrieve the echo of a sound one transmitted has been perceived to…

Predictive validity is the ability to measure something to predict a specific variable in the future. For example, the SAT use predictive validity to predict how well a high school student will do in college. This related to the result of the written exam because predictive validity measures the connection between the score of a test and the target behavior. So if the test result of the written exam is high, the correlation between the score and the targeted behavior will have a high predictive…

The article “What is the amygdala” by Swanson and Petrovich asks whether the concept of structurally and functionally defined amygdala is truly valid or whether the concept is imposing illogical categorization on diverse structures that belongs to different functional systems. The authors discuss evidence that support latter is the case. Evidence from immunochemistry for GABA and in situ hybridization for glutamic acid decarboxylase suggest that the extrinsic projections of the central amygdalar…

Reduced prefrontal cortical gray matter value in young adults exposed to corporal punishment is a study done by Akemi Tomoda, Hanako Suzuki, Karen Rabi, Yi-Shin She, Ann Polcari, and Martin H. Teicher. This study was published in March 2009 and had the objective to see how harsh corporal punishment during a persons childhood changes the brain structure and specifically the amount of gray matter volume. They clearly drew guidelines on the differences between harsh corporal punishment (HCP) and…

7 cranial nerve pairs out of 12 pairs in human nervous system function more or less in speech or hearing; these are the cranial nerves V (Trigeminal), VII (Facial), VIII (Vestibulocochlear), IX (Glossopharyngeal), X (Vagus), XI (Spinal Accessory), and XII (Hypoglossal). These have particular roles other than assisting speech or hearing. Furthermore, most clinical tests for cranial nerve functions neither are recommended to be performed by speech and hearing pathologists, nor are they related to…

Burning Question: What are all the parts of the brain and what are their functions ‘Brainy’ Facts The brain. You couldn’t live without it. It helps you move, breathe, eat sleep, et cetera. It is the most complex organ and controls all of your body’s functions. When I was in kindergarten, I had an accident and fractured my skull, had a minor brain bleed and a small concussion In first grade, I had surgery to fix up my brain and skull. All of these injuries took a major toll on my brain. The…

Description of Research Any injury or damage to your brain can result in devastating motor or cognitive lost. The extent of this lost typically depends on the amount of damage caused and the point of injury. After receiving a brain injury, the most severe form of motor disability someone can have is Locked-in syndrome (LIS) (Pistoia et al., 2016). “It is the consequence of ventral brainstem damage as a result of vascular or traumatic lesions disconnecting corticospinal and corticobulbar…

and role playing for different communication strategies. In the Dyukova, Glozman, Titova, Kriushev, & Gamaleya (2010) article right hemisphere stroke patients were studied. It was found that dichotic listening and object naming with separate visual stimulation of the visual field had an impact on recovery. They overall concluded that stutter in right-hemisphere strokes is typically associated with deautomation of the flow of speech and mutism can occur. In the Schlaug, Marchina, & Wan (2011)…

Did you know that possessing a greater amount of dopamine receptors in the hippocampus results in better episodic memory? It’s a wonder why some people have great memory of past events, while others have none. As an adult it gets increasingly harder to remember events you experienced as a child. It has always been a phenomenon as to why you can’t remember the memories you had as a child. Why you forget what happens before the age of four. As an infant your brain is busy making new cells in the…
