What happens in the brain when people think about the future? Neuroscientist find that two sub-networks play a role. One focuses on creating the new event. Another evaluates whether that event is positive or negative.

Neuroscientists present a new theory for what's happening in the brain when something looks familiar. The work brings the field one step closer to understanding how memory functions. Long-term, it could have implications for treating diseases like Alzheimer's.

When neuroscientists analyzed the exact properties of nerve connections in the brain, they made a startling observation: At a key connection, or synapse, messages are sent against the usual stream of information. The study reports that the signal glutamate likely plays a role in this unusual transmission.

Alzheimer's disease shares some key similarities with healthy aging, according to a new mathematical model.

Cultural diversity -- indicated by linguistic diversity -- and biodiversity are linked, and their connection may be another way to preserve both natural environments and Indigenous populations in Africa and perhaps worldwide, according to an international team of researchers.
