RA activity consistently covaried with sleep state and subtle EEG characteristics. The data suggest a distinct role for REM sleep in learning, to accentuate specific features of bursting activity during sleep.

520 $a RA activity consistently covaried with sleep state and subtle EEG characteristics. The data suggest a distinct role for REM sleep in learning, to accentuate specific features of bursting activity during sleep.
520 $a Learning is a multi-stage process involving encoding, consolidation (stabilization and enhancement) and maintenance of memories. Sleep participates in memory consolidation, in part, through reactivation of previously encoded memory traces. Individual premotor neurons in the song system of the sleeping adult zebra finch recapitulate patterns seen during singing, but it is unknown what behavioral role this plays in adults or during juvenile song learning, a time of profound behavioral change. We set out to systematically describe sleep in the zebra finch and to define a role for sleep-specific neural activity in song learning.
520 $a Zebra finches presented with a complex sleep structure more similar to mammalian species than previously reported for birds, including high amounts of rapid eye movement sleep (REM). Non-REM (NREM) sleep showed periods of clear slow wave sleep (SWS) and a lower EEG amplitude "intermediate" sleep (IS). SWS and REM exhibited a mammalian-like ultradian rhythm. We also observed brief periods of unihemispheric sleep, characterized by asymmetrical eye states (one open, one closed), and EEG signatures. REM sleep has been widely associated with a role in procedural learning. Higher amounts of REM sleep in oscines maybe a permissive factor in the emergence of song learning or the two may have necessarily evolved in parallel.
520 $a We explored sleep's role in song learning through examination of sleep physiology of single neurons in the premotor robust nucleus of the arcopallium (RA), across the experimentally controlled onset of song learning. We observed that high frequency bursts of activity in RA neurons during nighttime sleep depended heavily on birds' experience with auditory feedback on previous days, and carried information specific to the song that birds had memorized and were attempting to copy. This information was first expressed on the night prior to changes in singing behavior. The sensory information expressed in a premotor area during sleep suggests a learning process whereby information is transferred across modalities during sleep.
