A Dartmouth-led study in Science Advances finds that information used to counter myths about Zika in Brazil not only failed to reduce misperceptions but also reduced the accuracy of people’s other beliefs about the disease.

Revving habits up and down, new insight into how the brain forms habits

Each day, humans and animals rely on habits to complete routine tasks such as eating and sleeping. As new habits are formed, this enables us to do things automatically without thinking.

This activity burst increases as the habit becomes stronger. A Dartmouth study demonstrates how habits can be controlled depending on how active the dorsolateral striatum is. The results are published in the Journal of Neuroscience.
