A Northwestern University study that will be published in the Proceedings of the National Academy of Sciences (PNAS) provides the first biological evidence that bilinguals’ rich experience with language in essence “fine-tunes” their auditory nervous system and helps them juggle linguistic input in ways that enhance attention and working memory.
A new drug to manage resistant chronic pain
Neuropathic pain, caused by nerve or tissue damage, is the culprit behind many cases of chronic pain. It can be the result of an accident or caused by a variety of medical conditions and diseases such as tumors, lupus, and diabetes.

Overlooked nighttime spikes on EEGs may reflect an underlying brain injury
Children with developmental delay or autism may have unrecognized epilepsy-like brain activity during sleep, report researchers at Boston Children’s Hospital.
