Treatment strategy provides mental health benefits to war trauma survivors

A study shows that a certain intervention called testimony therapy plus ceremony reduced symptoms of posttraumatic stress disorder, anxiety, and depression among Khmer Rouge torture survivors from across Cambodia.

Older, fitter adults experience greater brain activity while learning

Older adults who experience good cardiac fitness may be also keeping their brains in good shape as well. In what is believed to be the first study of its kind, older adults who scored high on cardiorespiratory fitness (CRF) tests performed better on me…

Multiregional brain on a chip

A multiregional brain-on-a-chip that models the connectivity between three distinct regions of the brain has been revealed by researchers. The in vitro model was used to extensively characterize the differences between neurons from different regions of…

Sensory stimuli control dopamine in the brain

The type and intensity of stimuli control the activity of nerve cells that release the neurotransmitter dopamine, report scientists.

Scientists find new mechanism for memory formation

New research investigates how we form memories, and discovers that apart from the hippocampus, a previously neglected brain area plays a crucial role.

Found: Neurons that orient bats toward destination

Bats – like humans – can find their favorite fruit stand (or coffee shop) even when it’s hidden behind a screen or tall buildings. How? Scientists have now identified the neurons that point bats in the right direction, even when their destination…

New system for forming memories

Until now, the hippocampus was considered the most important brain region for forming and recalling memory, with other regions only contributing as subordinates. But a new study finds that a brain region called entorhinal cortex plays a new and indepen…

Macaques, like humans, know how well they can recall memories

Researchers have pinpointed a brain region monkeys use to evaluate their ability to recall memories. To date, this metamemory process, which requires a higher level of self-reflection about our own cognition, was thought by some to be unique to humans,…

Cannabis: Non-addictive pathway to pain relief?

New research suggests an avenue for developing treatments for chronic pain that harness the medicinal properties of cannabis while minimizing the threat of addiction. Therapeutics that target the endocannabinoid system might produce pain relief with fe…

Viruses in genome important for our brain

Over millions of years retroviruses have been incorporated into our human DNA, where they today make up almost 10 per cent of the total genome. A research group has now discovered a mechanism through which these retroviruses may have an impact on gene …
