but exciting emerging research shows that chocolate may be good for both cardiovascular health and even memory.
and had detailed assessment of people's diets that was collected in real-time as people consumed the foods rather than relying on past memory.
These sticky amyloid proteins--which may form in regions of the brain involved in memory learning
and gregarious forms also have different memory and learning abilities to suit the needs of the two life stages.
and colleagues exploited the locust's ability to associate an odour with a reward--which in the wild allows it to make quick food choices--to study the memory
nevertheless to use different learning mechanisms as revealed by the different times it takes them to gain the aversive memory (4 hours for solitarious locusts and 24 hours for the gregarious).
but this time while solitarious locusts learned to avoid vanilla--so gained the negative memory--neither transiens nor gregarious locusts could do it.
Since crowding blocks new negative memories could the old negative memory be replaced simply by a positive one?
even if crowding cannot eliminate a previous memory by temporarily blocking new aversive memories it permits an update of it
and memory abilities to suit different life stages in a remarkable show of insects'survival skills.
and committed to memory. Talking with some of the people in these towns and cities,
Johns hopkins university in Baltimore  observed that people who took a caffeine pill scored higher on memory tests than did swallowed those who a dummy tablet, the BBC reportsâ in a summary of an article in Nature Neuroscience.
The two groups scored equally on easier memory tasks. None of the subjects were regular caffeine consumers.
The NMDA receptors help control memory and synaptic plasticity. Theanine may also have positive effects on serotonin levels to promote restful Sleep in rats,
