The N-methyl-D-aspartic acid (NMDA) receptor dysfunction in the brain of aged animals has been shown. In older rodents, N-methyl-D-aspartate receptor 2B subunit gene expression declines significantly associated with memory impairment. To further reveal this process, Dr. Chunxia Li and colleagues from East China Normal University, China analyzed gene expression profiles in the neocortex of aged Tg mice. Pathway and signal-net analyses identified multiple pathways altered in the transgenic...

Bird Brains Help In Study Of The Mammalian Neocortex
2012-10-02 11:02:13

April Flowers for redOrbit.com - Your Universe Online Humans and other mammals have a seemingly unique part of the brain called the neocortex, which is a layered structure on the outer surface where higher-order processing is thought to occur. A new study from the University of Chicago found similar cells in the brains of birds, but in a vastly different anatomical structure. Confirming a 50-year hypothesis about the identity of a mysterious structure in the bird brain, the new study...
