Scientists discover how the human brain folds
February 1, 2016

gel model of brain ft 
Understanding how the brain folds could help unlock the inner workings of the brain and unravel brain-related disorders, as function often follows form
Folded brains likely evolved to fit a large cortex into a small volume, with the added benefit of reducing neuronal wiring length and improving cognitive function. But how does the brain fold? A simple mechanical instability associated with buckling, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences, collaborating with scientists in … more…


Graphene is ideal substrate for brain electrodes, researchers find
February 1, 2016

graphene-neuron interface ft An international study headed by the European Graphene Flagship research consortium has found that graphene is a promising material for use in electrodes that interface with neurons, based on its excellent conductivity, flexibility for molding into complex shapes, biocompatibility, and stability within the body. The graphene-based substrates they studied* promise to overcome problems with “glial …more…
