Cerebrum

Pierre Paul Broca revolutionized our modern understanding of the imperative role neuronal lesions have in determining the functionality of an individual’s speaking abilities. Specifically, his greatest contribution relates to the locating of aphasia within the cerebral cortex, and determining which region of the brain was specialized for producing articulate speech. Eventually classified as Broca’s area (Page 75), it exists upon the left frontal lobe, and predominately functions to regulate and encourage

Writing Assignment Unit 4 – Brain Unit A. The brain is the most important organ for regulating human behavior and thought. The brain is very complex and has taken centuries to discover how it functions. The brain is separated into four distinct regions or lobes. These regions are called the frontal lobe, the occipital lobe, the temporal lobe, and the parietal lobe. The frontal lobe is located directly behind the forehead and is the brain region that controls higher level thinking such as memory

Roger Sperry was a psychologist and neuroscientist whose main work focused on the left and right hemispheres of the brain (Hockenbury and Hockenbury 2014). Roger Sperry’s area of research was categorized as neurophysiology. Sperry’s most famous research dealt with split-brain operations where the corpus callosum has been completely severed (Hockenbury and Hockenbury 2014). The corpus callosum consists of a bundle of neurons that are responsible for the communication between the two hemispheres of

The hippocampus, which is the Latin word for seahorse, is named because of the shape it holds (Hippocampus). It is the neural center in the limbic system (Myers, 368). This system is located in the temporal lobe, close to the center of the brain. The hippocampus is essentially involved with the storage of long-term memory, especially of past knowledge and experiences (Hippocampus). The hippocampus is also vitally important to the creation of new memories, and without it humans would always be living

Physical Activity’s Impact on the Hippocampus Ana Arredondo The hippocampus is a miniature structure within the brain that plays a crucial role in the limbic system. The limbic system, known for regulating emotions among other functions, is located in the medial temporal lobe. The importance of the hippocampus relies on multiple aspects of memory. When information is processed from the environment, the hippocampus manipulates it by arranging and storing information from short term into long-term

Symptoms of Wernicke’s aphasia vary among patients due to different extents and locations of damage to the temporal lobe. The most common symptoms include “notable anomia, poor auditory comprehension, and poor repetition ability (Esstabrooks & Albert, 2014). Other common symptoms include jargon which is nonsense words, paraphasic speech, both impaired reading and writing skills and meaningless speech. Although their speech is meaningless and includes nonsense words it is said “linguistically,

A motor unit is made up of a motor neuron and the muscle fibers that it supplies depending on its size. The motor neuron controls the amount of force that is exerted by muscle fibers. There are two principles that control the relationship between motor neuron and muscle force, the size principle and rate coding. The size principle decides which motor units are recruited first. For example, recruitment is seen in larger muscles that have mixed fiber types such as the latissimus dorsi. Rate coding

BACKGROUND The ability of the human visual system to integrate facial features into a gestalt whole is one of the processes that seems to contribute the most to human face perception (referred to as holistic face processing; Taubert et al.; 2006). A large number of behavioral studies provide evidence that demonstrate that faces are processed holistically. Two examples that provide evidences for holistic processing are the composite effect and the part-whole effect. In composite effect tasks, participants

ONE BRAIN OR TWO? M.S. Gazzaniga, 1967, studied the split brain in people. He wanted to see how the two halves of the brain functioned by themselves. It was not until other discovered that cutting the corpus callosum actually stopped severe epileptic seizures that it was possible for Gazzaniga and Sperry to study them that made it okay. Gazzaniga found that the test peoples personality, intelligence and emotions did not change in any way. We use each half of our brains for specific skills. Three

There are four lobes that make up the complex organ that we call the brain. Each of these parts or lobes have different functions that range from reasoning to auditory perception and make that particular person so unique. Some people have stronger and well more developed lobes in which is why not everyone is the same and could mean one section is inferior to the rest. To begin with, the frontal lob, which is located in the front of the human head, is associated with reasoning, higher level cognition
