Abstract

Growing for a song Previous studies have demonstrated a correlation between structural changes in the brain and sensory experience, but whether similar changes accompany learning is uncertain. High-resolution two-photon in vivo imaging of individual neurons in the song control nucleus HVC (higher vocal centre) of juvenile zebra finches that were learning adult song patterns suggests that learning does involve such changes. Within 24 hours of learning their first song, the normally dynamic dendritic spines in the HVC of the zebra finches become larger and more stable, and synaptic activity is enhanced.
