AUTOMATIC collects and analyzes information about the brain.
In the study of brain physiologist into a world of huge numbers: 10 billion neurons in the human brain, 150 billion between, neural elements, over 1 000 billion of connections between neurons, and so on. Measure, calculate, process, those billions - not an easy task, but without the actual material is impossible to build a model.
Modern computers are hundreds of times increase productivity by freeing people from drudgery. If you use the TV input of the information "directly from the microscope, the computer can be used to collect data on the number of cells in various parts of the brain. Principles that need to lay the computer account for the cells are fairly simple. Computer cannot just assume the cell, but to classify
their size, the color. The principles laid in it, naturally, more complicated. Current oscillations in the cerebral cortex (EEG) recorded about a hundred years. Bioelectrical brain activity reflects a variety of changes, both in the external environment and internal processes of the body. In this diverse and complex relationship of the brain with the entire organism and environment is the cause of large variability of EEG records. Assessment of EEG reading it - it is not easy, requiring little experience. During the work of different groups of brain cells biocurrents fluctuations are superimposed on each other, outwardly manifested in the form of a complex wave process. Mathematical processing of electroencephalograms facilitates their decoding.
Potential difference arising between two points of the cortex is insignificant and is 50-200 mV, but this is enough to register it. The first explorers, who rented the EEG in humans, only two used the overhead electrode, one placed on the forehead and the other - on his head, and recording vibration potentials of the brain. It was then increased the number of electrodes, there are two systems of abstraction biopotential.
