Cerebral Cortex
Study
finds brain hub that links music, memory and emotion
By using fMRI to map
brain activity of college students as they
listened to a variety of tunes from their younger years, then comparing
the activity to the students' responses to questions about each tune, a
researcher at the University of California, Davis, has found that the
dorsal medial prefrontal cortex is a hub that responds to music, memory
and emotion.

Re-shaping
the family: What happens when parents seek siblings of their

Parents who have
conceived children with the help of sperm or egg
donors and then try to find the donors and also other children
conceived with the donors' help, often end up creating new forms of
extended families, according to research published in Europe's leading
reproductive medicine journal, Human Reproduction, on Tuesday, Feb. 24.

No
longer a gray area: Our hair bleaches itself as we grow older
Wash away your gray?
Maybe. A team of European scientists have solved a
mystery that has perplexed humans throughout the ages: why we turn
gray. These researchers show in a research report published online in
the FASEB Journal that going gray is caused by a massive build up of
hydrogen peroxide due to wear and tear of our hair follicles. The
peroxide winds up blocking the normal synthesis of melanin, our hair's
natural pigment.

A report published in the current issue of the journal Psychological

A team of UC Riverside researchers has identified all the genes

molecular pathways that stem cells employ, the discovery also can help
scientists better understand why stem cells -- in both plants and
animals -- give rise to specialized cells at all.

Stunning finding: Compounds protect against cerebral palsy
Two compounds developed by Northwestern University chemists have been
shown to be effective in pre-clinical trials in protecting against
cerebral palsy, a condition caused by neurodegeneration that affects
body movement and muscle coordination. There was a remarkable
difference between animals treated with a small dose of one of the
compounds and those that were not. The findings suggest a preventive
strategy for cerebral palsy may be feasible for humans in the future.
