The paper investigates reward expectation signals in the superior colliculus during associative learning and finds that the SC carries a learned reward-expectation signal multiplexed with motor preparation.

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.

The paper shows that dopaminergic signals for reward and performance shift during courtship in songbirds, with signals routed through distinct pathways based on social context.

The paper identifies songbird subthalamic nucleus (STN) neurons that signal song timing and error, projecting to VTA and connected to brain regions involved in song learning.
