MONDAY, May 31, 2004 (HealthDayNews) -- Even after you've returned from a vacation, you may be still fully recall the sights, sounds tastes and smells of some of its particularly memorable moments.
For years, neurobiologists have tried to understand the brain functions that enable this type of detailed recollection.
A study in the May 27 issue of Neuron confirms previous models of memory recall that found sensory-specific components of a memory are preserved in sensory-related areas of the brain. The hippocampus can draw on this stored sensory information to create vivid recall.
For their study, the researchers mapped brain activity in human volunteers who sampled different odors and viewed pictures of various objects.
