Aging in humans, as well as in experimental animals, is associated with a slow deterioration of cognitive performance especially in memory, reaction time, and reasoning abilities (Gallagher and Rapp 1997; Grady and Craik 2000).
ImPACT® is a brief computer-administered neuropsychological test battery consisting of six neuropsychological test modules that measure cognitive functioning in attention, memory, reaction time, and processing speed.
Deficits in visual motor tasks, mental flexibility, (verbal) memory, reaction times, and attention have been reported in MTLE patients after surgery.
In those early waking minutes, our memory, reaction time, ability to perform basic mathematical tasks, and alertness and attention all suffer.
Composite scores from these modules are reported in five domains: verbal memory, visual memory, reaction time, processing speed, and impulse control.
Despite the volume of work done on models incorporating memory in reaction, diffusion, or both, there appear to be very few appearances in the literature of diffusion models in which such terms are present in the boundary flux.
Models involving memory terms in reaction have arisen in studies of nuclear reactor dynamics [1, 2] and population dynamics [3], specifically in the case of logistic growth models involving both nondelayed and hereditary effects [4, 5].
The disturbed memory B-cell formation points towards an impaired germinal center reaction in secondary lymphoid organs of most CVID patients.
WHEN the Swedish Academy called the Chinese writer Mo Yan to tell him he had won this year's Nobel Prize in Literature, the novelist reportedly told them, in what must be one of the most poignant Nobel reactions in memory, that he was "overjoyed and terrified".
In a British study published in The Journal of Applied Physiology, researchers recruited 10 men and 6 women to perform a computer exercise requiring concentration, memory and reaction speed.
