New Map Shows Where Tastes Are Coded in the Brain PDF Print E-mail
Wednesday, 07 September 2011 00:23
Each taste, from sweet to salty, is sensed by a unique set of neurons in the brains of mice, new research reveals. The findings demonstrate that neurons that respond to specific tastes are arranged discretely in what the scientists call a "gustotopic map." This is the first map that shows how taste is represented in the mammalian brain.

Brain Grows While Body Starves If Growth Is Restricted Before Birth PDF Print E-mail
Wednesday, 07 September 2011 00:21
When developing babies are growth restricted in the womb, they are typically born with heads that are large relative to their bodies. The growing brain is protected at the expense of other, less critical organs. Now, researchers reporting in the August 5th issue of Cell, a Cell Press publication, unearth new molecular evidence that explains just how the brain is spared.
