Strange but True: Less Sleep Means More Dreams Sep 22, 2007
"We follow the [electroencephalogram] tracing and then when we see [subjects] moving into REM, we wake them up," says psychologist Tore Nielsen, director of the Dream and Nightmare Lab at the Sacr;-Coeur Hospital in Montreal. "As soon as you start to rob them of REM, the pressure for them to go back into REM starts to build." Sometimes Nielsen will have to wake them 40 times in one night because they go directly into REM as soon as they are asleep. (Scientific American)
Mice Used In Research Helpful In Multiple Research Areas Sep 3, 2007
O'Hara's study takes advantage of noninvasive piezoelectric sensors instead of conventional techniques that use electroencephalogram and eletromyogram recordings, which require surgical implants and cables that tether the mouse to a recording device. This limitation has made it impractical to study large numbers of animals, which is necessary in genetic screening, according to O'Hara. (Science Daily)

Sleep-Wake Controls Identified: Implications For Coma Patients And Those Under Anesthesia Jul 26, 2007
The electroencephalogram, or EEG, of the waking brain shows fast rhythms of 10-60 cycles per second, while the sleeping brain cycles at frequencies below 10 per second. Electrical coupling would allow many cells to fire together, generating a rhythm that is transmitted to other parts of the brain to induce changes in sleep-wake states. (Science Daily)
