New technique scans electrical 'brainscape'

...said. "We know that moods are fairly ephemeral or fleeting so that even though we are affected by these experiences, our mind has the ability to digest them and reset by the next day," he said.

...monstrated in animal models and cell cultures that fleeting insults can damage neurons by causing an "excitotoxic" overload of the neurotransmitter glutamate. Earlier brain tissue culture studies had shown that complement could damage brain cells called astrocytes preferentially over neurons, said McNamara. ...New approach to imaging separates thought from perception
...hitedots on a dark screen. The trials began with a fleeting glimpse of an arrow,which indicated that some of the dots would move in a particular direction (cueperiod). The subjects then had to press a key if they saw dots moving in thatdirection among dots that were moving in random directions (test period). ...UI study indicates physicians' questions are often not pursued
...tors share any and all questions, even the "vague, fleeting uncertaintiesthat [doctors] would normally keep to [themselves]." After 21 months, Ely and his team tabulated 1,101 questions. The researchers organized these questions into topics and general types anddetermined some key trends. Doctors had the most...NYU/U. Rochester team find neurons in visual cortex adapt to images within .5 seconds of viewing
...noccurs so rapidly, it can develop even during the fleeting stops our eyes makewhen we scan an image, and this can help us distinguish small differencesbetween the things we see on successive stops." Coauthor Peter Lennie said, "Neuroscientists have long know that that firststage of the visual cortex analyzes...
