Hippocampus News and Research

RSS

The hippocampus is a part of the forebrain, located in the medial temporal lobe. It belongs to the limbic system and plays major roles in short term memory and spatial navigation. Humans and other mammals have two hippocampi, one in each side of the brain.

Decoding anxiety: Study reveals brain's role in behavioral inhibition risks

Researchers in the U.S. used non-human primate models to explore the molecular mechanisms and neural systems behind behavioral inhibition, a key risk factor for anxiety disorders. The study identified molecular systems in the posterior orbitofrontal cortex linked to variations in anxious temperament, offering potential targets for treating anxiety disorders.

Spicing up memory: Wasabi found to boost brainpower in seniors

A 12-week study on adults over 60 found that wasabi supplements containing 6-MSITC significantly improved episodic and working memory. While other cognitive domains showed no improvement, the findings suggest that wasabi's anti-inflammatory and anti-oxidant properties may offer new avenues for combating age-related memory decline.
