What is the Origin of REM Sleep Neurogenesis?

This concept is derived from sleep science and neurobiology, linking the distinct physiological state of REM sleep, characterized by active brain waves and muscle atonia, to the biological process of neurogenesis, the birth of new neurons. Research suggests a temporal and functional coupling between these two processes.

What is the Mechanism of REM Sleep Neurogenesis?

During REM sleep, specific neurotransmitter systems are highly active, and there is an increased expression of neurotrophic factors, such as Brain-Derived Neurotrophic Factor (BDNF), which is a key regulator of neuronal survival and differentiation. The high level of synaptic plasticity and active circuit rehearsal that occurs during this sleep stage is thought to provide the necessary environment and stimulus for the maturation and functional integration of newly generated neural stem cells.

REM Sleep Neurogenesis

Meaning

REM Sleep Neurogenesis refers to the hypothesis that the Rapid Eye Movement (REM) stage of sleep is a critical period for the generation of new neurons and the integration of new neural circuits within the brain, particularly in the hippocampus. This process is vital for memory consolidation, learning, and maintaining cognitive flexibility and resilience. Adequate REM sleep is thus a fundamental component of neurohormonal health.
