Recently, physicians seeking to resolve a patient's conscious state have gone right to the source, searching for signs of awareness using brain imaging or recording electrical activity of neurons. (sciencemag.org)
The researchers measured electrical activity of the neurons within the ensemble and compared it with nearby neurons that were not activated by the environmental cue. (sciencedaily.com)
Their objective was to discover if the theta and gamma - coupled oscillations observed in the auditory cortex are key to understanding and produce speech, or if they are only its consequence, that is, the expression of electrical activity of neurons mobilized at that time. (sciencedaily.com)
