Sleep can help brain to reorganize memories found a new study published in Nature Communications journal.
Researchers at the Humboldt and Charité Universities in Berlin, led by Dr.Julie Seibt from the University of Surrey, used cutting-edge techniques to record activity in a particular region of brain cells that is responsible for holding new information - the dendrites.
The study, published in Nature Communications, found that activity in dendrites increases when we sleep and that this increase is linked to specific brain waves that are seen to be key to how we form memories.
"Sleep spindles have been associated with memory formation in humans for quite some time, but nobody knew what they were actually doing in the brain. Now we know that during spindles, specific pathways are activated in dendrites, maybe allowing our memories to be reinforced during sleep".
"In the near future, techniques that allow brain stimulation, such as transcranial magnetic stimulation (TMS), could be used to stimulate dendrites with the same frequency range as spindles. This could lead to enhance cognitive functions in patients with learning and memory disorders, such as dementia."
