Researchers Pinpoint Site For Petit Mal Seizures In Brain
...processes higher functions such as language. "In a sense the thalamus is thought to be the gateway to consciousness," Hosford said. "During a petit mal seizure, the thalamus switches to a burst pattern of signal transmission, similar to what we see in sleep. In a sense, the petit mal seizure is like a mome...Duke Researchers Find Second Gene Linked To Blood Vessel Disorder
...is injured and needs to be repaired. "This makes sense with what we know about the disease," Marchuksaid. "Children with HHT usually don't show any signs they have thedisease. But as they age, and presumably acquire mechanical damage to tinyblood vessels that need to be repaired, the disorder shows up." ...Discovery Of Cell Sites May Shed Light On How Bodily Systems Interact
...cells in the pituitary also have the eyes that can sense the presence ofdisease-causing bacterium."

...e, making it much gentler," Dunn said. "The way we sense when the probe is near the sample is by vibrating the probe back and forth and watching the amplitude of that movement." When the probe gets close to the sample's surface, the movement of the probe's tip is reduced by the sample, he said. This is use...A Drug Pump On A Computer Chip

"Ideally, an insulin delivery pump would sense the patients blood glucose level and change the dose of insulin accordingly," said Huff, who has begun with a pump and a flow sensor to ensure a constant pumping rate. An insulin sensor would have to be added later. Huffs prototype consists of a...Pets Provide Physiological Benefits For Women Living Alone

"In an area where we know bark beetles are present, we'd, say, make a Douglas fir smell like a cottonwood," say...UF Researchers Investigate Phenomenon Of Seizure-Alert Dogs
