Hippocampus News and Research RSS Feed - Hippocampus News and Research

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.

Brain uses a mechanism to filter out distracting thoughts to focus on single information

19. November 2009 06:29
The human brain is bombarded with all kinds of information, from the memory of last night's delicious dinner to the instructions from your boss at your morning meeting. But how do you "tune in" to just one thought or idea and ignore all the rest of what is going on around you, until it comes time to think of something else? [More]

New neuroimaging techniques yield new insights on Alzheimer's disease

18. November 2009 04:11
Brain imaging can offer a window into risk for diseases such as Alzheimer's disease (AD). A study conducted at the University of Kansas School of Medicine demonstrated that genetic risk is expressed in the brains of even those who are healthy, but carry some risk for AD. The results of this study are published in the November 2009 issue of the Journal of Alzheimer's Disease. [More]

Scientists develop new technique to measure brain volume loss for monitoring of Alzheimer's disease

16. November 2009 23:09
In a study that promises to improve diagnosis and monitoring of Alzheimer's disease, scientists at the University of California, San Diego have developed a fast and accurate method for quantifying subtle, sub-regional brain volume loss using magnetic resonance imaging (MRI). The study will be published the week of November 16 in the Proceedings of the National Academy of Sciences (PNAS). [More]
