New evidence touch-sensing nerve cells may fuel ‘ringing in the ears’

We all know that it can take a little while for our hearing to bounce back after listening to our iPods too loud or attending a raucous concert. But new research at the University of Michigan Health System suggests over-exposure to noise can actually cause more lasting changes to our auditory circuitry – changes that may lead to tinnitus, commonly known as ringing in the ears.

Imaging study shows how humor activates kids’ brain regions

For the first time, researchers have scanned the brains of children watching funny videos to examine which of their brain regions are active as their sense of humor develops. The new findings from the Stanford University School of Medicine show that some parts of the brain network that respond to humor in adults already exist in 6- to 12-year-olds, though the neural circuits become more sophisticated as kids grow.
