Algorithm reveals how a small region in our brain plays a key role in motivation

A small region of the brain, known as the ventral tegmental area (VTA), plays a key role in how we process rewards. It produces dopamine, a neuromodulator that helps predict future rewards based on contextual cues. A team from the universities of Geneva (UNIGE), Harvard, and McGill has shown that the VTA goes even further: It encodes not only the anticipated reward but also the precise moment it is expected.

Alzheimer’s gene therapy shows promise in preserving cognitive function

Researchers at the University of California San Diego School of Medicine have developed a gene therapy for Alzheimer’s disease that could help protect the brain from damage and preserve cognitive function. Unlike existing treatments for Alzheimer’s that target unhealthy protein deposits in the brain, the new approach could help address the root cause of Alzheimer’s disease by influencing the behavior of brain cells themselves.
