The Case of the Disappearing Spindle Burst

摘要: Sleep spindles are brief cortical oscillations at 10–15 Hz that occur predominantly during non-REM (quiet) sleep in adult mammals and thought to contribute learning memory. Spindle bursts phenomenologically similar spindles, but they early infancy triggered by peripheral sensory activity (e.g., retinal waves); accordingly, spindle organize neural networks the developing brain establish functional links with periphery. Whereas spontaneous waves trigger visual cortex a transient feature of development, myoclonic twitches drive sensorimotor persist into adulthood. Moreover, twitches—and their associated bursts—occur exclusively REM (active) sleep. Curiously, despite persistence twitching adulthood, twitch-related have not been reported cortex. This raises question whether such burst does adulthood or, alternatively, occurs has yet be discovered. If do adults, could calibration, maintenance, repair systems.
