People who had cognitive functions depleted by noninvasive brain stimulation or a mentally demanding task could subconsciously recognize individual words in a made-up language more easily than controls, researchers find.
Neurons in the hippocampus store information on the timing of experiences in addition to their content, helping to mediate sequential memory recall, a new study shows.
To tease apart brain regions involved in forming versus remembering memories, scientists engineered mice whose brain cells could be manipulated and tagged.
Early on, researchers had learned that the hippocampus was the structure in the brain where long-term memories were created and stored, but it was not known whether the different cell types within this structure might be more or less susceptible to the aging process.
