Early deafness may reshape the brain to devote more resources to peripheral vision
People with intact hearing can use sound as an alert system for events outside their direct line of sight. This seemingly puts those who have lost their hearing at a disadvantage. However, according to a new study published ...
Gut infection may train immune sentries at the brain's border to remember microbes
The brain and spinal cord are highly protected treasures of the central nervous system, wrapped under three protective layers of meninges. The outermost layer, the dura mater, has leaky windows through which bacteria or parasites ...
