The Human Brain - ... This is followed by a testing phase in which the object is presented simultaneously with a new distinctive object. In this experiment the participant is then required to distinguish between the repeated object and the new object. The finding was that participants with temporal lobe damage have impairment in making the distinction between the repeated experience and the novel experience when both are presented side by side especially after a long delay between study and test. The indication was that the delay presents interferences which affect the perception of the experiences....   [tags: Health, Diseases, Brain Damage] 1190 words

The brain - Occipital, Frontal, and Temporal Lobes The occipital lobes are the center of our visual perception system. They are not particularly vulnerable to injury because of their location at the back of the brain, although any significant trauma to the brain could produce subtle changes to our visual-perceptual system, such as visual field defects and scotomas.

The Human Brain - INTRODUCTION The human body is divided into many different parts called organs. All of the parts are controlled by an organ called the brain, which is located in the head.

The brain flashes messages out to all the other parts of the body. The messages travel in very fine threads called nerves.

Endorphins and serotonin are released in large amounts (Smiga). They are the feel-good chemicals of the body, increasing mood and the sense of security and well-being (Britt). These feel-good chemicals are important, but dopamine again serves as the most important chemical. The dopamine released during initial attraction only activated the body's reward system, but as levels increase and more of that natural high is experienced, it is so strongly craved that the reward system tells the body it must repeat the behaviors that caused its initial release (Bozarth)....   [tags: Psychology]

Meditation and the Brain - Meditation and the Brain When discussing the relationship of brain and behavior, the materialist view of human experience runs into conflict with the historically dominant religious accounts. Recent studies, however, suggests that there may be a "middle view" between the two world-views. Religions, especially Buddhism, stress the role of meditation in one's spiritual growth. Meditation has tangible psychological and physiological benefits, though, which can be explained strictly in neurobiological terms....   [tags: Biology Essays Research Papers]

The Human Brain - Our brains weigh about three pounds and are divided into two similar looking but functionally different hemisphere, the right hemisphere and the left hemisphere. Both of which are connected by a large bundle of nerves called the corpus collosum. In some people with severe seizure disorders such as epilepsy, it was found that if this bundle of nerves was severed their seizure would either cease or a the very least be better controlled. From this surgical procedure it was discovered that the two hemispheres had different methods of processing information, as well as controlling parts of the body....   [tags: essays research papers] 1348 words

Schizophrenia and the Brain - ... Although even with advances in modern science and new drugs being developed every day, the illness is still only treatable and its symptoms still emerge even with proper medication. Even with its origin unknown, scientists have discovered several chromosomes which when damaged or mutated, greatly increase the risk of developing schizophrenia. The chromosomes in particular that act as catalysts are chromosome numbers twenty-two, six, and eleven (Klar, 2004). Chromosome six contains several genes that are linked with immune response which has given rise to the belief that schizophrenia has some association with weakened disease fighting agents....   [tags: Mental Health, Diseases] 1865 words

Recreating the Brain - 2001: Recreating the Brain Perhaps one of the most interesting and least understood aspects of neurobiology is human consciousness. For many, this "experience of self" (an aspect of consciousness which will be used interchangeably with consciousness in this particular paper) defines what it means to be human. Personality and emotion, and their connection to the experience of self, can yield insight into creating artificial intelligence that can mimic conscious human brain function. By discussing the implications of consciousness in computers with artificial intelligence, the significance of the experience of self within humans becomes clearer....   [tags: Biology Essays Research Papers]

His studies in young cats showed that entire networks of brain cells could be routed around damaged areas. Young animals whose primary vision centers were destroyed could still learn to see normally, he found, because cells in another part of their brains took up the job of processing vision....   [tags: Biology Essays Research Papers]

Linking the mind to the brain would invalidate Searle's (1980) explanation that artificial intelligence is impossible because the brain is irrelevant when the mind is concerned. In other words, programs require machines to run, but the mind is independent of the brain. Recent findings suggest that the brain is directly linked to the mind, so even creating AI machines will be possible in the future because the mind is obviously linked to the body through the brain and the nervous system. Although new theories on human consciousness will obviously assist AI engineers, those theories will question the reliability of Dualism because they suggest that mind is a material substance that takes a certain space and creates certain manifestations in the body....   [tags: Anatomy, Nervous System] 1321 words
