SENILITY
SENILITY
SENILITY Senility is a disease commonly referred to as dementia. It affects 4 million Americans every year and is a major cause of disability in old age (Bunch, 1997, p. 106). Its prevalence increases with age (Bunch, 1997, p. 106). Dementia is characterized by a permanent memory deficit affecting recent memory in particular and of sufficient severity to interfere with the patient's ability to take part in professional and social activities (Bunch, 1997, p. 106). Although the aging process is as

Controlling Computers With Neu
Controlling Computers With Neu In the classic science-fiction movie Forbidden Planet, space travelers from Earth land on a distant planet, where they encounter the remnants of a technologically advanced civilization. Even though they are not from this distant planet, the space travelers are able to communicate with one of the alien computers. They do this by connecting themselves to glowing head probes. By doing this the space traveler\'s thoughts and feelings are directly conveyed to the alien

Brain Wave Genereation
Brain Wave Genereation Theory behind BrainWave Generator EEG and the brain's state EEG (Electroencephalography) technology is used to measure brain's electrical vibrations from the surface of the scalp. The resulting EEG pattern will contain frequency elements mainly below 30Hz. The frequencies are categorized into four states as follows: State Frequency range Amplitude State of mind Delta 0.5Hz - 4Hz high (up to 200uV) Deep sleep Theta 4Hz - 8Hz low (5uV - 20uV) Drowsiness (also first stage of

Trisomy 21 Down Syndrome
Trisomy 21 Down Syndrome
Trisomy 21 Down Syndrome Trisomy 21 is caused, as the name suggests, by the triplication of the 21st chromosome. Genes which, simplified, contain the blueprints for our cellular structure, are grouped along rod-like structures called chromosomes. Normally, the nucleus of each cell contains 23 pairs of chromosomes, half of which are inherited from each parent. In Down syndrome (DS), however, the cells usually contain not 46, but 47 chromosomes. This excess genetic material, in the form of additio
