Rapid spine stabilization and synaptic enhancement at the onset of behavioural learning
2010
The brain's capacity to respond to instructive capacity underlies behavioural learning, but how instructive experience acts on the juvenile brain, a period in which learning is often enhanced, remains unknown. Here, two-photon in vivo imaging is used to study the brains of zebra finches as they learn to sing. The results indicate that behavioural learning results when instructive experience is able to rapidly stabilize and strengthen synapses on the sensorimotor neurons that control the learned behaviour.
