Italian scientists uncover 'sleep switch' in brain


Genoa, January 22 - Scientists in Italy have made a
breakthrough in understanding how the brain regulates sleep,
possibly clearing the way for new treatments of sleep disorders.
Researchers at the Italian Institute of Technology (IIT)
have located the "switch" used to slow brainwaves produced
during sleep, according to a report published in the journal
Nature Neuroscience.
"This study represents, to the best of our knowledge, the
first causal demonstration that excitatory circuits located in
distinct cortical layers differentially control spontaneous
low-frequency dynamics," it said.
The so-called switch is in fact a neuronal subgroup located
in the deep layers of the cortex, according to researchers led
by Doctor Tommaso Fellin.
The scientists say they have unlocked how it works, thus
paving the way for future breakthroughs in treating sleep
disorders and other related maladies.
