Stimulating brain with ultrasound can influence decisions

A study in macaques reveals that targeting a brain region with noninvasive, low-intensity ultrasound can alter a specific decision-making process.

Taking care of people with TBI: New tool could speed caregiver research

A traumatic brain injury happens in an instant: a battlefield blast, a car crash, a bad fall. But the effects can last a lifetime — and can leave the survivor dependent on daily care from their loved ones for decades. Now, a new tool seeks to give a v…

Gender identity leaves imprint on human brains

Society’s expectations about gender roles alter the human brain at the cellular level, according to a new article.

Cannabidiol could help deliver medications to the brain

Cannabidiol (CBD), a non-psychoactive compound in cannabis, is being touted as beneficial for many health conditions, ranging from anxiety to epilepsy. Although much more research is needed to verify these claims, scientists have now shown that CBD cou…
