An allergy drug showed promise for MS, but could they prove it?
What if an over-the-counter allergy medicine could help halt and even reverse multiple sclerosis? And if it did, could patients return to their full capacity? Those were some of the questions first posed in 2013 after a landmark ...

Sensory signals are integrated differently, underrepresented by neurons in autism
In fragile X syndrome (FXS), the most common cause of autism, sensory signals from the outside world are integrated differently, causing them to be underrepresented by cortical pyramidal neurons in the brain.

Novel optical and fMRI platform identifies brain regions that control large-scale brain network
When we daydream or revisit memories, a large group of regions within our brain "lights up," or becomes more active. It's referred to as the Default Mode Network (DMN) because it is more active when the brain is not focused ...
