Functional magnetic resonance imaging

Diagnostic tests used in diagnosis and management Individuals with no or only minor symptoms are often diagnosed as a result of family screening, detection of a murmur during routine examination, or the identification of an abnormal ECG. Any individual suspected of having HCM should undergo a comprehensive cardiac history and physical examination and an electrocardiogram (ECG). ECG testing is the most sensitive routinely performed diagnostic test for HCM, but the ECG abnormalities are not…

such as scans and computer programming, have allowed for tests and simulations which have proved the idea of dyslexic people processing in a different part of the brain and a lower amount of activity than non-impaired people. With MRIs, magnetic resonance imaging, researchers observe and document brain activity when an individual is asked to complete a distinct cognitive task (Shaywitz). Professors of Pediatrics and Neurology Sally E. Shaywitz and Bennett A. Shaywitz have conducted experiments…

Adolescence was first used in 1950, adolescence comes from the Latin word adolescence which means “grow up into a maturity” (Muuss, 1990). But before this Aristotle and Plato already gave some perspective about this. Aristotle proposed a developmental stage not too far from the modern youth developmental stage. According to Cortis A. (2015), the adolescence is a change on the self-esteem of the person that involves the changes in physical, physiological temporal and cultural lenses. During…

Congenital abnormalities and pathologies are some of the most fascinating diagnostically. Situs inversus, a condition in which the organs of the body are flipped to face the other side, is one of the most enthralling to behold. Typically occurring genetically, it is extremely rare, occurring only in 0.01% of the population (Nall, 2014). This congenital abnormality can be demonstrated on not only diagnostic radiography, but also computed tomography and ultrasound. The prognosis for patients…

Suppressing bad memories from the past can block memory formation in the here and now, research suggests. The study could help to explain why those suffering from post-traumatic stress disorder (PTSD) and other psychological conditions often experience difficulty in remembering recent events, scientists say. Writing in Nature Communications, the authors describe how trying to forget past incidents by suppressing our recollections can create a “virtual lesion” in the brain that casts an…

With use of magnetic resonance imaging (or MRI) technology we have dicovered, structul differences in hippocampal and prefrontal cortex volumes (brain areas associated with memory, and executive functions of planning, inhibition, self-regulation, respectively) (Wetherill & Tapert…

Structural and functional data about the healthy healthy further suggest cerebellar participation in higher-level neural networks. The aforementioned studies contribute to an exciting paradigm shift for understanding cerebellar function. Instead of exclusively controlling…

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…

People are awake the majority of the day, but a large portion of the day is consumed by sleeping. A good night’s rest is essential because without an appropriate amount of sleep, the hours spent awake can become impacted. Unfortunately, sleep disorders can affect a person’s sleeping abilities. Narcolepsy is one example of a sleep disorder that will affect someone at night and through the day. Narcolepsy can be defined as a neurological disorder where the person experiences daytime sleepiness…

The word "addiction" is defined in a different variety of ways, but the general definition of such refers to a compulsive drive to engage in some activity or substance that is clearly harmful to our bodies. Within the Washington Post article, "Video-game addiction a real problem, study finds" written by Donna St. George, and the report, "Online Game Playing Is not Addictive," by Peter Gray, the argument about dangers of video games are discussed, as well as their consideration about the level of…
