Socially-induced brain ‘fertilization’: play promotes brain derived neurotrophic factor transcription in the amygdala and dorsolateral frontal cortex in juvenile rats
Researchers studied 32-day-old juvenile rats that were allowed 30 minutes of rough-and-tumble play. Right after play, the rats showed higher levels of BDNF messenger RNA in the amygdala and dorsolateral frontal cortex, measured with in situ hybridization. The authors suggested this could mean play helps shape brain areas tied to…
