Human multitasking is the best performance by an individual of appearing to handle more than one task at the same time. The term is derived from computer multitasking. An example of multitasking is taking phone calls while typing an email. Some believe that multitasking can result in time wasted due to human context switching and apparently causing more errors due to insufficient attention. Etymology The term "multitasking" originated in the computer engineering industry.[1] It refers to the

Chapter 1: “The Phantom Within” Modularity vs. Holism Modularity – different parts of the brain are highly specialized for mental capabilities. (i.e.‚ FFA‚ module for language‚ and etc…) Holism – “connectionism”; many areas‚ especially cortical regions‚ can be recruited for multiple tasks. *** Ramachandran believes these two views are not mutually exclusive. The brain is a dynamic structure that employs both “modules: in a marvelously complex interplay. (uses Baywatch as an analogy‚ saying

From an investigation of the connection between strain components in uniaxial tests‚ this research conducted a mixture of experimental and numerical analysis to determine the damage constitutive constraints of the brain tissue by exploiting nonlinear optimization method. To do that‚ a mixture of the gray and white matters of the brain tissue were imaged using MRI and then the tractography approached was used to determine the angle of collagen fibers in them. Finally‚ the tissue samples were subjected

Trauma is a part of everyone’s life. Some people are affected outwardly‚ others are not. Trauma does not have to be a traumatizing event‚ sometimes it can just be the stress of everyday life taking an overwhelming toll on the body and the mind. Trauma can change a person for the rest of their life. It can change their behavior‚ personality‚ and even the size of their hippocampus. The hippocampus‚ which is the center for emotion and memory‚ is a very important part of the brain. When most people think

Biological level of analysis – serotonin Serotonin is a neurotransmitter which plays different roles in our brain‚ and can have effects such as sleep‚ arousal levels and emotion. The study was conducted by two researchers‚ Kasamatsu and Hirai‚ at Tokyo’s University in 1999. The aim of the study was to find out how the sensory deprivation affects the brain and later on‚ the human behavior. In order to achieve their aim‚ the researchers examined a group of Buddhist monks who went to a religious

Apraxia: An Overview It is undisputed that there is a predisposition in human behavior to imitate and mimic those around us. It is even thought that this ability is endowed in humans from the time of birth. Newborns‚ for instance‚ first begin to imitate the gestures of their caregivers. Even adults have a tendency to mimic behaviors or attitudes. One neurological disorder‚ however‚ may debilitate this tendency. This is one of the most prominent characteristics of apraxia. According to Rachel

7 July 2013 Brain regions where ideas become contagious identified by Will Parker How do ideas spread? Why do some videos go viral? UCLA scientists have taken a first step toward answering these questions by identifying the brain regions associated with the successful spread of ideas. The research‚ reported in the journal Psychological Science‚ has broad implications and could lead to more persuasive advertisements and better ways for teachers to communicate with students. The study suggests

There are three major brain divisions. They are the cerebrum‚ the brainstem‚ and the cerebellum. The cerebrum contains 40% of the weight of the brain and is founded in the superior part of the brain. This portion of the brain has many functions and lobes which perform certain functions. The frontal lobe is involved with “activating and controlling both fine and complex motor activities.” This involves speech. It is also involved with the executive functions‚ such as reasoning and rationalizing‚ among

The Parietal Lobe The brain is a fascinating yet complicated structure. Without it our involuntary functions while we sleep and our natural reflexes would vanish. Every part of our nervous system works together‚ it becomes one whole. One fundamental part of our brain‚ that is probably one of the most important to the disabled‚ is the Parietal Lobe which receives impulses that control one of our most important senses; touch. The Parietal Lobe is located near the center of the brain‚ behind the frontal

Cerebellum The Cerebellum (Latin for “little brain”) is the section of the brain responsible for motor controls coordination and perception. The Cerebellum is considered one of the most important parts of the brain partly due to the fact that‚ although being only 10% of the size of the entire brain‚ it contains over 50% of the neurons found in the brain. The Cerebellum is located in the lower rear section of the brain and it almost looks separate for the brain itself. The most
