Sharp waves, bursts, and coherence: Activity in a songbird vocal circuit is influenced by behavioral state

The paper investigates neural activity patterns in the songbird anterior forebrain pathway during sleep and awake states, finding synchronized bursts in LMAN during NREM sleep similar to hippocampal sharp-wave ripples.

Local sleep in songbirds: Different simultaneous sleep states across the avian pallium

The paper examines local sleep states in zebra finches, finding that sleep stages vary across different regions of the avian pallium, challenging the idea of global sleep states.

Multi-channel recordings reveal age-related differences in the sleep of juvenile and adult zebra finches

The paper examines age-related changes in sleep patterns and neural activity in zebra finches, finding differences in sleep stages and functional connectivity between juveniles and adults.

Hippocampal-like network dynamics underlie avian sharp wave-ripples

The paper identifies sharp wave-ripples (SWRs) in birds during sleep and anesthesia, suggesting their evolutionary origin predates the mammalian-sauropsid split.
