Is striatal FoxP2 actively regulated during songbird sensorimotor learning?
Hearing appears to link FoxP2 levels to the amount of vocal practice. As juvenile birds spent more time practicing than did adults, their FoxP2 levels are likely to be low more often. Behaviorally-driven reductions in the mRNA encoding this transcription factor could ultimately affect downstream molecules that function in vocal exploration, especially during sensorimotor learning.
The findings indicate that simply eliminating stigmatizing media portrayals of obesity may help reduce bias.
