Clot buster? Surgery? What is the right treatment for stroke?

During an ischemic stroke, blood vessels in the brain are blocked or narrowed. During a hemorrhagic stroke, there’s bleeding into the brain. The first treatment for stroke is to potentially offer a medication called tissue plasminogen activator (TPA) that helps dissolve blood clots. This is often called a clot buster. It has to be given within 4.5 hours from when symptoms began.

Scientists are unraveling the cause behind sudden unexpected death in epilepsy

In the United States, nearly three million adults 18 years and older reported having active epilepsy during 2021 and 2022. SUDEP (sudden unexpected death in epilepsy), however, is rare, occurring in one in 1,000 people and resulting in an estimated 3,000 deaths per year. Its rarity has shrouded it in mystery, although some theories point to seizures disrupting the heart and breathing, ultimately leading to death.

Goalkeeper or corner? Neuroscientists show how the brain enables flexible decisions

Our brain is remarkably flexible in producing different reactions to supposedly comparable situations. The same sensory information can lead to different decisions depending on the behavioral context. One example of this is a penalty kick in soccer: a player can either choose the empty corner of the goal as the target or aim directly at the goalkeeper in the hope that he will jump aside. Both decisions are based on the same perception of the goalkeeper’s position, but lead to completely different actions.
