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.

Unveiling the brain mechanism behind memory consolidation in sleep

Neuroscientists have established in recent decades the idea that some of each day's experiences are converted by the brain into permanent memories during sleep the same night.

Novel treatment approach to halt epilepsy progression identified

Only a very small percentage of neurons show changes after an epileptic seizure in mice, but these alterations can be permanent and trigger future seizures that can affect the whole brain and lead to impaired cognition, like memory and learning, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

How the brain switches between daydreaming and reality

When we daydream, we must be able to snap back to attention at a moment's notice. Researchers at Boston Children's Hospital uncovered how our brains can do things like react to a question when we're daydreaming: firing activity in part of the brain called the dentate gyrus keeps us focused on what's happening in our environment.
