Bat brains parse sounds for multitasking

Imagine listening to music while carrying on a conversation with friends. This type of multi-tasking is fairly easy to do, right? That’s because our brains efficiently and effectively separate the auditory signals – music to the right side; conversation to the left. But what researchers have not been able to do in humans or animals is to see a parsing of duties at the single neuron level – until now.

fMRI predicts outcome of talk therapy in children with an anxiety disorder

A brain scan with functional MRI (fMRI) is enough to predict which patients with pediatric anxiety disorder will respond to talk therapy, and so may not need to use psychiatric medication, say neuroscientists from Georgetown University Medical Center. Their study, being presented at the annual meeting of the Society for Neuroscience in San Diego, showed that children and adolescents, ages 8 to16, who show fear when looking at happy faces on a screen inside an fMRI scanner were those who had least success with an eight-week course of cognitive behavioral therapy.
