What is the name of the process for consolidating memories whos dating piper perabo
The question is, does the mechanism that promotes sleep also consolidate memory, or do ...Biology 202 1998 Second Web Reports On Serendip Aldous Huxley's Brave New World considers the possibility of humans learning simply by listening to recorded messages played during their sleep. It is speculated that Non REM sleep is the time that the body and brain use to rebuild themselves after a long period of wakefulness (1). Scientists have speculated that REM sleep performs many functions among them development of the brain, synthesis of neuro-proteins, and coordination of eye movements (1).Research strongly suggests that sleep, which constitutes about a third of our lives, is crucial for learning and forming long-term memories.But exactly how such memory is formed is not well understood and remains, despite considerable research, a central question of inquiry in neuroscience. Their study provides for the first time a mechanistic explanation for how deep sleep (also called slow-wave sleep) may be promoting the consolidation of recent memories."These patterns of slow oscillations remain even without further input from the hippocampus," said Yina Wei, a postdoctoral researcher and the first author of the research paper."We interpret these results as a mechanistic explanation for the consolidation of specific memories during deep sleep, whereby the memory traces are formed in the cortex and become independent of the hippocampus." Study results appear in the .During sleep, human and animal brains are primarily decoupled from sensory input.Nevertheless, the brain remains highly active, showing electrical activity in the form of sharp-wave ripples in the hippocampus (a small region of the brain that forms part of the limbic system) and large-amplitude slow oscillations in the cortex (the outer layer of the cerebrum), reflecting alternating periods of active and silent states of cortical neurons during deep sleep.
REM sleep is a period late in the sleep cycle in which the brain and body become active, increasing heart rate and blood pressure.
Wei explained that according to the biologically realistic network model the researchers used, input from the hippocampus reaches the cortex during deep sleep and influences how the slow oscillations are initiated and propagated in the cortical network.
"Input from the hippocampus -- the sharp-wave ripples -- determines the spatial and temporal pattern of these slow oscillations," she said.
Each cycle consists of NREM sleep followed by REM sleep, and roughly lasts 90-110 minutes.
NREM sleep has three stages, Stage 3 being deep sleep.
