Neurometrics
Neurometrics is the science of measuring the underlying organization of the brain's electrical activity. Certain brainwave frequencies are associated with general psychological processes. EEGs are used to measure the brain waves. Overview According to E. Roy John, the pioneer in the field of neurometrics, neurometrics is In 1977, Roy John and Robert Thatcher published one of the first texts in the field of neurometrics. The text was entitled ''Neurometrics''. The field of Neurometrics began to expand significantly in the 1990s. This was due in part to the advent of inexpensive methods of linking computers to traditional EEG devices. This allowed researchers to transform analog EEG signals into digital signals for statistical analysis. Leading researchers in the field included Frank Duffy, E. Roy John, and Robert Thatcher. Between the 1980s and the present time, thousands of articles in the field of neurometrics have been published. Entrepreneurs began to take notice of ...

Neural Oscillation
Neural oscillations, or brainwaves, are rhythmic or repetitive patterns of neural activity in the central nervous system. Neural tissue can generate oscillatory activity in many ways, driven either by mechanisms within individual neurons or by interactions between neurons. In individual neurons, oscillations can appear either as oscillations in membrane potential or as rhythmic patterns of action potentials, which then produce oscillatory activation of post-synaptic neurons. At the level of neural ensembles, synchronized activity of large numbers of neurons can give rise to macroscopic oscillations, which can be observed in an electroencephalogram. Oscillatory activity in groups of neurons generally arises from feedback connections between the neurons that result in the synchronization of their firing patterns. The interaction between neurons can give rise to oscillations at a different frequency than the firing frequency of individual neurons. A well-known example of macrosco ...
