Tutorial: The Brain The brain was a mystery for a very long time. Modern imaging has allowed us to study the brain and locate where important functions are occurring. Please remember that the functions do not happen in just one area of the brain. Many neural layers and areas are found in any one activity that happens. But what we do know though is that some areas do appear to be predominantly involved in certain functions. We will learn about the brain in the three-part model. We’ll first look at

1 Critical Review No. 2: His Brain‚ Her Brain Abstract As Larry Cahill ’s article “His Brain‚ Her Brain”‚ points out there has been data showing a vast “...array of structural‚ chemical and functional variations” between the sexes; but does size matter? Lawrence Summers‚ former President of Harvard‚ thought so. Men ’s brains are 13% larger than women ’s brains‚ but does that really make them more advanced in math‚ physics and science? There are other anatomical variations and some of these

Twin Win Birth is not a choice. You have no decision on your parents‚ standard of living or location. It just is. As for me‚ I was gifted with something money could not buy: an “identical” twin. But that word doesn’t seem quite right. . Even though some may think that since I am an identical twin I am half a man‚ not true‚ I would not be half the man I am today without my twin brother. Having someone who is the same age‚ growing up in the same environment and perceiving things similarly makes it

The Magician’s Twin “Have I really done this? Am I capable of doing it? Probably I am. I have done such things in the past so I might have repeated such a thing. But the things I have done in the past are so petty compared to this.” he thought to himself. He did not want to think about it anymore- being accused of something he had or had not done. He wasn’t sure. This uncertainty made him more anxious and his head throbbed with pain. John Wilson‚ the son of a small time magician‚ Henry Wilson‚

Left Brain Vs. Right Brain Learning Theory Left Brain vs. Right Brain Learning Theory The left brain versus right brain learning theory states that each side of the brain controls different types of thinking. These different types of thinking are said to be dominant in different types of people. It is postulated that people are either left or right brain thinkers‚ and it is complicated for a person to try to think any differently than they already know how. The idea was raised in the 1860’s

Current Issues in Brain Imaging Technology Brain imaging technology has revolutionized the way doctors‚ scientists‚ and researchers are able to see the workings of this highly complex organ. The use of brain imaging techniques allows for discovery without the use of invasive surgical procedures. Now used throughout the globe‚ these techniques have matured dramatically in the last century. With its roots in the early twentieth century using low-tech devices‚ brain imaging has evolved dramatically

Twin Peaks was not a typical television show in the early 1990’s. Most television shows are made up of characters that are so pretty‚ so rich‚ or so cool that they become dehumanized and unrealistic. However‚ the characters in Twin Peaks are the exact opposite. They are unglamorous‚ odd‚ and sometimes just plain silly. Were the creators of Twin Peaks trying to break away from the use of common‚ stereotypical characters? Well‚ they were actually taking an old idea and turning it around. Just

1.INTRODUCTION What is a Brain-Computer Interface? A brain-computer interface uses electrophysiological signals to control remote devices. Most current BCIs are not invasive. They consist of electrodes applied to the scalp of an individual or worn in an electrode cap such as the one shown in 1-1 (Left). These electrodes pick up the brain’s electrical activity (at the microvolt level) and carry it into amplifiers such as the ones shown in 1-1 (Right). These amplifiers amplify the signal

Schizophrenia is a complex brain disorder. Like many other illnesses‚ schizophrenia is believed to result from a combination of environmental and genetic factors. All the tools of modern science are being used to search for the causes of this disorder. The term schizophrenia is Greek in origin‚ and in the Greek meant "split mind." This is not an accurate medical term. In Western culture‚ some people have come to believe that schizophrenia refers to a split-personality disorder. These are two very
