Cro Magnon skull shows that our brains have shrunk
(PhysOrg.com) -- A new replica of an early modern human brain has provided further evidence for the theory that the human brain has been shrinking. The skull belonged to an elderly Cro Magnon man, whose skeleton ...
On the move: 'Jumping genes' create diversity in human brain cells
Rather than sticking to a single DNA script, human brain cells harbor astonishing genomic variability, according to scientists at the Salk Institute for Biological Studies. The findings, to be published in ...

Neuronal diversity makes a difference, study says
Much like snowflakes, no two neurons are exactly alike. But it's not the size or shape that sets one neuron apart from another, it's the way it responds to incoming stimuli. Carnegie Mellon University researchers ...
