other consisted of four wires that measured the animal's
brain waves.
There are clear patterns of
brain wave activity, hormone production, cell regeneration and
other biological activities linked to this daily cycle.
Memory
waves It is well established that sleep strengthens newly formed memories, and slow
brain waves are thought to enhance the transfer of information from the hippocampus, a
brain structure that is crucial to memory formation, to
other parts of the
brain for long - term storage.
So - called unihemispheric sleep happens in animals when one side of the
brain shows waking activity while the
other side is asleep (an electroencephalographic recording of
brain activity under these circumstances shows slow synchronous
waves).
But he and
other neuroscientists say the study may be fatally flawed because it uses technology that can not reliably distinguish one type of
brain wave pattern from
Merely being in each
other's presence, with or without touch, was associated with some
brain wave synchronicity in the alpha mu band, a wavelength associated with focused attention.

other frequencies of
brain waves improve memory, according to the paper presenting the results published online November 5 in Nature.

brain to a prosthesis,
others are taking a more direct route, reading
brain waves directly and using them to control the hand.

brain, Schiff has identified a few
brain -
wave patterns common to Wallis, Melendez, and a handful of
others who have made notable, though less spectacular, recoveries.
«During sleep, maybe specific
brain regions have slow waves at the same time because they need to exchange information with each other, whereas other ones don't,» says Laura Lewis, a research affiliate in MIT's Department of Brain and Cognitive Sciences and one of the lead authors of the new study, which appears in the journal e

The researchers believe the TRN fine - tunes the
brain's control over local
brain regions, enhancing or reducing slow
waves in certain regions so those areas can communicate with each
other, or inducing some areas to become less alert when the
brain is very drowsy.
By giving the
brain a series of nudges — in
other words, by triggering K - complexes — could they strengthen the
waves into a pattern that mimicked slow
wave sleep?
For example, two distant hubs in the circuit, one at the front of the
brain (right circle) and the
other at the rear side (left circle), showed varying amounts of synchrony in their
brain waves, depending on what object a monkey was holding in memory.
