different parts called organs. All of the parts are controlled by an organ called the brain‚ which is located in the head. The brain weighs about 2.75 pounds‚ and has a whitish-pink appearance. The brain is made up of many cells‚ and is the control centre of the body. The brain flashes messages out to all the other parts of the body. The messages travel in very fine threads called nerves. The nerves and the brain make up a system somewhat like telephone poles carrying wires across the city. This is

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.

Question 1 Given what we know about localization of function in the human brain‚ is it scientifically legitimate to categorize people as left-brained or right-brained? Hemispheric lateralization‚ as discovered by Roger W. Sperry (1965)‚ ascribes to the specialization of one cerebral hemisphere or the other in controlling specific functions (Passer‚ Smith‚ Holt‚ Bremner‚ Sutherland & Vliek‚ 2009). In recent years‚ there appears to be a growing phenomenon in the generalization

organs in the body‚ but the brain is affected most by drug use. The brain is complex and communicates via nuerons and nerve cells to command the body. The brain ensures the body performs the necessary functions for survial. Drugs can compromise the brain’s ability to properly communicate to the organs in the body. Drugs affect communication and a person’s behavior. The following presentation will provide an explanation as to how drugs affect the brain The brain is a network made up of nuerons

Left Brain vs. Right Brain: Implications of Learning Foundations of Online Learning Abstract A left-brain dominant person’s attributes are different than that of a right-brained person. This difference causes these two groups to have different learning styles. A left-brain dominant tends to be better at spelling and math. This is because this person can see all of the pieces. A right- brain dominant person tends be better at writing‚ biology‚ and other hands on subjects

Male Brain vs. Female Brain: Is one Better than the Other? Differences between males and females have been an issue affecting our society for thousands of years. Why are we so different? Why are we so similar? Several scientists have attempted to explain these variations‚ all using different methods and approaches. A very controversial study by psychologist J. Philippe Rushton suggested that men are innately more intelligent than women. This study gave arousal to several studies that oppose it

Biology Abstract In this experiment we used dried split peas to extract the DNA and observed the protein isolate. Introduction The purpose of the experiment was to learn what the process was to extract DNA. You also learned the characteristics of DNA and go to observe them. Hypothesis I think the DNA will be really interesting to observe. Procedure Material: * Alcohol * Blender * Water * Drinking glasses * Measuring cup * Paper towels * Freezer

The size of cylinder is 300mm length with 150mm diameter or 200mm with 100mm diameter. The specimen were kept in water for curing for 3 days‚ 7 days and 21 days and on test day remove and allow the surface to dry. The test is performed out by placing a cylindrical specimen horizontally

Left brain VS Right brain Matthew Stafford Davenport University 10/25/2012 Right Brain Your brain processes and reacts to certain situations in many different ways. This is directly due to either being left brain or right brain. What is left brain or right brain you ask? People use either side to approach solutions to a variety of problems with different outcomes. People who are left brain tend to approach each problem with an analytical point of view. Right brain thinkers tend to
