How fear memories get stuck in some brains

Researchers at Linköping University, Sweden, have discovered a biological mechanism that increases the strength with which fear memories are stored in the brain. The study, carried out in rats, is published in Molecular Psychiatry. ...

Exploring how many drinks is too many

A new rodent study shows that even small quantities of alcohol can trigger epigenomic and transcriptomic changes in brain circuitry in an area that is crucial in the development of addiction.

How does nature nurture the brain?

After a 60-minute walk in nature, activity in brain regions involved in stress processing decreases. This is the finding of a recent study by the Lise Meitner Group for Environmental Neuroscience at the Max Planck Institute ...
