She added this could specifically help medical and military training and further research could be carried out to see if sleep loss affected other brain and memory functions in a similar way.
BBC: Spatial memory works in a similar way in rats and humans
Kolodgy recommends using a "token, " another type of device based on flash memory that functions as a key, made by companies such as Rainbow Technologies.
Merging magnets with semiconductors would allow a chip to combine a computer's memory and logic functions.
But this bundle consists of layers of capabilities or functions: storage, memory, graphics, processing, input, display, communications, and odds and ends.
Neurophysiologists have recently discovered that Nitric Oxide (NO) plays a vital role in many brain functions, including learning and memory.
To a standard silicon layout from ARM, Luminary adds functions like Ethernet connections, flash memory and motion-control hardware.
Especially confusing, says Gazzaley, is that key brain functions, like short-term memory, processing speed, and the capacity to multi-task, decline steadily as we age.
Hawkins, who will continue to work as chief technical officer of Treo maker palmOne (nasdaq: PLMO - news - people ), already has his own research lab to study the neocortex, a massive part of the brain thought to hold such higher level functions as language, learning, memory and complex thought.
That is, as the disease progresses in the brain, those who have a greater "reserve" do not show symptoms of Alzheimer's -- memory loss and impairment of day-to-day functions -- as quickly.
Curiously absent from the spec sheet are any mention of Bluetooth or memory card support, but with the music and imaging functions, we imagine that there's at least a microSD slot tucked away in there somewhere.
The electroencephalograph picks up cognitive functions in 12 different regions of the brain, showing memory recall and the level of attention paid to visual and aural stimuli.
Oki will keep its memory-chip operation in business to supply system LSIs -- chips packing several functions on one silicon wafer.
There is also a crippling loss of nerve cells in brain areas involved in cognitive functions which leads to the main behavioural symptom, failure of the memory.
Top candidates include its memory chip business, its Itanium server chips and several smaller businesses based around other categories of computer components for functions like storage and networking.
This modeled application of an STT-MRAM integrating the memory as cache memory and recorded a two-thirds reduction in power consumption by a standard mobile chip set carrying out standard operating functions, a result confirming that the new MRAM element has the lowest power consumption yet achieved.
