Sleep contributes to the brain’s ability to change and reorganise itself and this can help people with learning and memory disorders. Researchers used cutting edge techniques to record activity in the dendrites. Dendrite is parts of brain cells that is responsible for keeping new information.
They discovered 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.
Human brain have the ability to change and adapt based on our different experiences, sleep is very important for the changes. A large proportion of these changes may occur during very short and repetitive brain waves known as spindles.
Sleep spindles have been associated with memory formation in humans. During spindles, specific pathways are activated in dendrites, allowing memories to be reinforced during sleep.
