We are all born with many things we take for granted. Properly developed brains, facial features in their correct places, and a life span longer than a few hours. Some children who are born with holoprosencephaly, or HPE, aren't quite as lucky. Victims of this disease suffer with various abnormalities to the face and brain, sometimes resulting in death. Their symptoms can range from almost normal facial features and brain development, to something most of us thought only occurred in fictional…

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…

A person’s adolescent years are a life changing and marking time. For years, people have believed that the time of rebellion that adolescents go through is part of a mystery that all young people experience. That significant period in an adolescent’s life is called the period of storm and stress. Adolescent storm and stress is not only inevitable, but it is a time where people have to be the most understandable with their young adults. Preventing the brain from developing is something that is…

striatal and the rest are cortical. Substantial amount of evidence shows us that most cortical projection neurons use glutamate and descending projections of striatum use GABA. This implies that non-GABA-projecting regions of the amygdala are part of the cortex. Furthermore, the CEA projects to visceral centers in the brainstem. Also, the extended cortical division of amygdala contains the cortical amygdalar nucleus (COA) - accessary olfactory bulb input as well as the rest of the COA, the…

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…

such problems arise, the patient should be referred to an ENT or audiologist. To test cranial nerve IX, the gag reflex involves a brisk and brief elevation of the soft palate and bilateral contraction of pharyngeal muscles evoked by touching the posterior pharyngeal wall. It is tested on the left and the right sides and the reflex response should be consensual (i.e., the elevation of the soft palate should be symmetrical regardless of the side touched). Unilateral nuclear or infranuclear…

The human brain, just like all the other parts of our body is unique. It gives us the power to speak, think and to solve problems. It works by using the electrical and chemical process to take in, organize, interpret, store and use information. The nervous system is divided into central nervous system (CNS) and peripheral nervous system (PNS). The CNS consists of the brain and spinal cord and they are the decision makers of the body. Sensory information gathering and action transmission occurs…

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…

Locked-in syndrome causes complete paralysis with the exception of eye movement, however the patient is completely conscious and aware of surroundings (Pistoia et al., 2016). According to Pistoia et al., (2016), due to the disconnection of the cortex and spinal cord in…
