Although listening to music is common in all societies, the biological determinants of listening to music are largely unknown. According to a new study, listening to classical music enhanced the activity of genes involved in dopamine secretion and transport, synaptic neurotransmission, learning and memory, and down-regulated the genes mediating neurodegeneration. Several of the up-regulated genes were known to be responsible for song learning and singing in songbirds, suggesting a common evolutionary background of sound perception across species.

The first study has been undertaken to determine underlying biological mechanisms that promote functional recovery of the blood-brain barrier after blast injury, demonstrating that treatment with the glucocorticoid, dexamethasone, after primary blast injury promotes rapid recovery of an in vitro model of the BBB. These findings may also help improve outcomes in brain-injured soldiers and civilians, reducing the length of their mandatory rest periods before returning to duty.
