Over the past few months at least half of the world's population has been affected by some form of lockdown due to COVID-19, and many of us are experiencing the impact of social isolation. Loneliness affects both mental and physical health, but counterintuitively it can also result in a decreased desire for social interaction. To understand the mechanics of this paradox, UCL researchers based at the Wolfson Institute and the Sainsbury Wellcome Centre investigated social behaviour in zebrafish. Their results are published in eLife.

New and diverse experiences are linked to enhanced happiness, and this relationship is associated with greater correlation of brain activity, new research has found. The results, which appear in the journal Nature Neuroscience, reveal a previously unknown connection between our daily physical environments and our sense of well-being. "Our results suggest that people feel happier when they have more variety in their daily routines -- when they go to novel places and have a wider array of experiences," explains Catherine Hartley, an assistant professor in New York University's Department of Psychology and one of the paper's co-authors.

Traumatic stress can cause aggression by strengthening two brain pathways involved in emotion, according to research recently published in JNeurosci. Targeting those pathways via deep brain stimulation may stymie aggression associated with post-traumatic stress disorder. The consequences of traumatic stress linger long after the stress ends. People suffering from post-traumatic stress disorder often display heightened aggression, caused by unknown changes in the amygdala.
