2. What does genius mean? Explain the difference between genius and savant.
A person who has an exceptional natural capacity of intellect, especially as shown in creative and original work in science, music, art, etc. The difference between genius and savant is that geniuses have exceptional intelligence in all areas, unlike savants who have spectacular talents despite having serious mental or physical disablities.
3. What is a stroke and how could it affect your mental functioning?
A blockage or hemorrhage of a blood vessel leading to the brain, causing inadequate oxygen supply and, depending on the extent and location of the abnormality, such symptoms as weakness, paralysis of parts of the body, speech difficulties, and, if severe, loss of consciousness or death. The specific abilities that will be lost or affected by stroke depend on the extent of the brain damage and most importantly where in the brain the stroke occurred. The brain is an incredibly complex organ, and each area within the brain has responsibility for a particular function or ability.
4. What is a functional MRI and how does it help us understand brain activity?
Magnetic resonance imaging (MRI) is a noninvasive medical test that helps physicians diagnose and treat medical conditions.MRI uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures.Detailed MR images allow physicians to better evaluate various parts of the body and determine the presence of certain diseases that may not be assessed adequately with other imaging methods such as x-ray, ultrasound or computed tomography.
5. What is the corpus callosum and what role does it play in your brain's activity?
Corpus callosum consists of nerve fibers and is placed on the longitudinal fissure, under the cerebral cortex. There are three parts of corpus callosum: genu (the front part), splenium (the bottom part) and truncus (located between these two parts).
The essential assignment of corpus callosum is to allow the two hemispheres to communicate. Because two hemispheres have completely different functions and responsibilities, they have to have something that will join these functions together, so that our brain could function properly as one organ. Corpus callosum is actually connecting these functions into one, carrying information from one hemisphere to another and vice versa. It is also responsible for lateralization of the brain, which means that it determines which side of the body will be preferred. Eye movements are regulated and coherent due to fast action of corpus callosum.
6. What is epilepsy and how might it affect your brain's abilities?
Epilepsy is a disorder of the central nervous system, specifically the brain. In epilepsy, the brain's electrical rhythms have a tendency to become imbalanced, resulting in recurrent seizures. A seizure occurs when the brain's nerve cells misfire and generate a sudden, uncontrolled surge of electrical activity in the brain. If seizures arise from a specific area of the brain, then the initial symptoms of the seizure often reflect the functions of that area and are usually damaged or altered.
Autism is a complex developmental disability that typically appears during the first three years of life and affects a person’s ability to communicate and interact with others. Autism is defined by a certain set of behaviors and is a "spectrum disorder" that affects individuals differently and to varying degrees.
8. What is Asperger's Syndrome?
Asperger's syndrome is a developmental disorder that affects a person's ability to socialize and communicate effectively with others. Children with Asperger's syndrome typically exhibit social awkwardness and an all-absorbing interest in specific topics. Doctors group Asperger's syndrome with other conditions that are called autistic spectrum disorders or pervasive developmental disorders. These disorders all involve problems with social skills and communication.
