They used a neural network running on IBM s latest soda-can-sized supercomputer that learned to recognize the different brain patterns that occurred prior to each of Herman s memories. Thus they could predict, most of the time, whether a memory would be happy or sad before Herman actually had the recollection They were now able to localize events in time with greater precision using their joint discovery of fractal Fibonacci numbers, which allowed them to probe between the integers. 

Understanding the brain patterns of the newly in love can teach us how to rekindle romance and boost the health of long-term relationships (Wit// St Journal, Feb. 13,2007). We know that novelty and new experiences engage the dopamine system, and when it is associated with your partner, it creates a link with your partner (Arthur Aron, Stony Brook University). 

All five senses feed into these brain patterns that serve as inner maps of the environment. As different as the five senses seem, they are all built on the same sodium/ potassium signaling chemistry. Once a sensation is triggered, its information is carried through the body by similar neurons and then is encoded and combined in the brain. If the information is useful, its brain area can be expanded and enhanced, and more sensory cells detect and discriminate other patterns. 

Problems involving routine calculations are solved much faster and more reliably by computers than by humans. Nevertheless, there are tasks in which humans perform better, such as those in which the procedure is not strictly determined and problems which are not strictly algorithmic. One of these tasks is the recognition of patterns such as feces. For several decades people have been trying to develop methods which enable computers to achieve better results in these fields. One approach, artificial neural networks, which model the functionality of the brain, is explained in this section. 

Alkyl mercury compounds in the blood stream are found mainly in the blood cehs, and only to a smah extent in the plasma. This is probably the result of the greater stabhity of the alkyl mercuric compounds, as well as their pecuflar solubiUty characteristics. Alkyl mercury compounds affect the central nervous system and accumulate in the brain (17,18). Elimination of alkyl mercury compounds from the body is somewhat slower than that of inorganic mercury compounds and the aryl and alkoxy mercurials. Methylmercury is eliminated from humans at a rate indicating a half-life of 50—60 d (19) inorganic mercurials leave the body according to a half-life pattern of 30—60 d (20). Elimination rates are dependent not only on the nature of the compound but also on the dosage, method of intake, and the rate of intake (21,22).

These eiTors occur, not in spite of the fact that someone is well-trained but because he or she is well-trained. Routine operations are relegated to the lower levels of the brain and are not continuously monitored by tbe conscious mind. We would never get through the day if everything we did required our full attention. When the normal pattern or program of actions is interrupted for any reason, errors are likely to occur. These slips are very similar to those we make in everyday life. Reason and Mycielska [1] have described the psychology of such slips. 

Ironically, many errors occur because a person is well trained. Routine operations are controlled by lower levels of the brain and are not continuously monitored by the conscious mind. When tlie normal pattern of action is interrupted, an error is more likely to occur. 

Glycosydation AChE and BChE carry 3 and 9, respectively, N-glycosylation consensus sequences attaching carbohydrate residues to the core protein via asparagines. Different molecular forms of the enzymes in various tissues, show different number and composition of carbohydrate residues. N-glycosylation at all sites was shown to be important for effective biosynthesis, secretion and clearance of ChEs from the circulation. Altered patterns of AChE glycosylation have been observed in the brain and cerebrospinal fluid of Alzheimer s disease (AD) patients, with potential diagnostic value. 

The terms convulsion and seizure are often used interchangeably and basically have the same meaning. A seizure may be defined as a periodic attack of disturbed cerebral function. A seizure may also be described as an abnormal disturbance in the electrical activity in one or more areas of the brain. Seizures may be classified as partial (focal) or generalized. Each different type of seizure disorder is characterized by a specific pattern of events, as well as a different pattern of motor or sensory manifestation.
