Neurotransmitters are chemicals that transmit signals across a synapse‚ a structure that permits to pass electrical or chemical signal to another cell from one neuron to another. Neurotransmitters are synthesized from converting substances that are readily available to the body such as amino acids‚ which are available from food and only need some converting into transmitters. Neurotransmitters crucial to daily life and functions. Scientists are uncertain exactly how many Neurotransmitters there are

BLUE BRAIN 1. Introduction The name of the world’s first virtual brain. That means a machine that can function as human brain. Computer simulations in neuroscience hold the promise of dramatically enhancing the scientific method by providing a means to test hypotheses using predictive models of complex biological processes where experiments are not feasible. Of course‚ simulations are only as good as the quality of the data and the accuracy of the mathematical abstraction of the biological

heart. Output usually appears on a long scroll of paper that displays a printed graph of activity on a computer screen. 2. What are the four types of brain waves and distinguish between them. Alpha waves – have frequency of (8-13 Hz). Waves are regular and rhythmic‚ are synchronous and have low amplitude. They signify an awake but calm brain. Beta waves – have frequency of (14-30 Hz). Waves are rhythmic but not so regular‚ and have higher frequencies. They signify wakefulness and alertness.

Have you ever heard that too much television can ruin a child’s mind? Malcolm Gladwell proposes in his article‚ “Brain Candy‚” that playing video games or watching television is just as important as reading a book. Gladwell is using rhetorical appeals to prove that in fact‚ video games are not dumbing down society. Pop culture is helping to improve test scores and knowledge. In “Brain Candy‚” Malcolm Gladwell does affectively use rhetorical appeals to convince his audience that pop culture is making

The brain is one of the most vital and complex organs in the human anatomy‚ enabling us to act and react to situations in our everyday lives. It is in the nervous system of all living things‚ with the exception of some invertebrates. The ability to hear‚ see‚ taste and smell all originate from the brain‚ making it an organ us humans cannot live without. The brain serves a human being a variety of functions. One of those functions the brain serves is Information Processing. Information processing

When Lara is walking toward the dorm after a long day of classes she begins to feel hungry. The subcortical structure in the brain that regulates hunger is the hypothalamus. The hypothalamus is located in the prosencephalon of the brain in the sub cortex referred to as the diencephalon (Rouse‚ 2015). Hypothalamus’ main job is to maintain homeostasis in the body (Rouse‚ 2015). Hormones from the hypothalamus aides to regulate functions in the body‚ some including: hunger‚ body temperature‚ thirst

Brain development in the first two years is the most important and critical. Maria Montessori referred to this time as of the "absorbent mind" Early brain development is the frame work for the road ahead. When and how the brain develops in the first two years will play a critical role into adulthood. At birth‚ the brain is the only incomplete organ. The brain will continue to grow through childhood and adolescents. During the first two years the brain is the most flexible and prepared to learn

During the growth and development of the brain‚ the physical structures and neural pathways of the brain can change dramatically. Various regions of the brain may grow‚ new synapses may be created‚ or unused synapses may be pruned off. The ability of the brain to change and adapt has been called plasticity. In the TED talk “The Growing Evidence of Brain Plasticity”‚ Dr. Michael Merzenich makes a case for brain plasticity and proposes ways this ability can be used to help various mental disorders
