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.
Recording
the electrical activity of neurons directly from the surface of the brain, the scientists found that for a simple task, such as repeating a word presented visually or aurally, the visual and auditory cortexes reacted first to perceive the word.
Although this first model will depict only
the electrical activity of the neurons, future versions will also simulate chemicals in the brain, of interest because the combination of electricity and chemistry may cause thought.
A faster alternative would be to record
the electrical activity of neurons, but the wires required to do this are invasive and tend to be relatively large.
They began by characterizing the cell composition, protein expression, metabolism, and
electrical activity of neurons from each region in vitro.
Meck has found support for his model by recording
the electrical activities of neurons and in other researchers» studies on people with a skewed sense of time.
Sophisticated neuroimaging machines and brain - computer interfaces detect
the electrical activity of neurons, enabling us to decode and even alter the nervous system signals that accompany mental processes.
Whether we experience the feeling of «redness,» the appearance of «squareness,» or emotions such as love and hate, these are the results of
the electrical activity of neurons in our brain.
This is bad news, because the reason we put electrodes in the brain is to record
the electrical activity of those neurons.
NYSCF — Robertson Investigator Alumnus Ed Boyden, PhD, and his team at the MIT Media Lab have recently developed a new tool for imaging
the electrical activity of neurons in the brain using a fluorescent protein that glows when the neuron is active.
Astrocytes help
the electrical activity of neurons, so having healthy astrocytes could be good for an HD brain.
«It was known that ageing interferes with oscillations in
the electrical activity of neurons in the suprachiasmatic nucleus — the brain region responsible for regulating the circadian clock — making these oscillations lose amplitude, and it was assumed that other tissues would also lose their rhythms,» explains Guiomar.
