In the transition to awareness, the squiggly EEG signals —
electrical patterns generated by the collective activity of the neurons in the cortex — make a distinctive shift.
When researchers looked at their brain activity during these times, they saw that one hemisphere of the brain had
electrical patterns resembling nighttime sleep, whereas patterns from the other hemisphere indicated wakefulness.
«Heartbeat could be used as password to access electronic health records: Researchers use heart's
electrical pattern as encryption key for electronic records.»
Later, when the rats were asleep and their brain waves indicated that they had entered the stage in which humans normally dream, these
same electrical patterns appeared.
«They might detect changes in blood chemistry or in the heart's
electrical pattern, predict the onset of a heart attack, and broadcast a warning to your physician's mobile device.»
Scientists from that same study also concluded that the seemingly otherworldly memories from an NDE give off
electrical patterns that are similar to real memories and significantly different from imagined events.
This recovery phase is characterized by an increase in
an electrical pattern called slow - wave activity, which can be measured with a non-invasive technique called an electroencephalogram.
«Until now, it was quite challenging to accurately measure
the electrical patterns of stomach activity in a continuous manner, outside of a clinical setting.
From studies of electrical recordings of the rat hippocampus (an area of the brain associated with memory formation and storage), made while the rats were awake and learning a maze, Wilson and Louie found that
some electrical patterns were quite specific and identifiable, depending on what the rat was doing.
The electrical patterns showed that in order to make the correct choice, the mouse had to rely on short - term memory — recalling how many dots it saw on one side a few seconds prior — and then convert this memory into motor action, or the action of turning left or right.
This new sequence of activity coexisted with
the electrical pattern that was spontaneously generated when the neural culture was initially linked.
This may help to reset
the electrical patterns affecting the heart muscle.»
Since nothing moves but
the electrical patterns, the storage drive is «solid state.»
