Electrical activity of the brain: Mechanisms and interpretation

Abstract

Pulse generating anemometers have been incorporated into a computer-controlled data acquisition system for taking meteorological measurements. A computer accepts data in digital form, and pulses from 16 anemometers can be fed into the computer via a single general purpose interface card. The interrupt system is used directly to record and count the pulses, and the necessary programmes use only 222 locations of memory. The final on-line output consists of five-minute and hourly averages of wind speed from each of the sensors and a plot of wind profiles. The system has been used successfully for three years and has now collected over 3000 hours of data. The computer method described is immediately applicable to other types of pulse-generating instruments.

Electroneuromyographic studies of pain sensitivity

“…At the same time, the amplitude and frequency characteristics of the afterdischarge strictly correlate with the respective parameters of the spontaneous cerebral electrical activity. This allows researchers to conclude that the afterdischarge is closely related to the activity of the thalamic rhythmogenic structures, a component of the nonspecific cerebral systems [126,127]. The after discharge depends on the intensity and some other characteristics of stimulation.…”

Dissipative Structures and Self-Organization Process in an Abstract Model of Neural Network

“…The dissipative structure will provoke a correlation within the whole system using the associated symmetry-breaking process; this can be memory [9,10,11,12,13].…”
