Embryonic stem cell transplant restores memory, learning in mice

For the first time, human embryonic stem cells have been transformed into nerve cells that helped mice regain the ability to learn and remember. A study at the University of Wisconsin-Madison is the first to show that human ...

Going places: Rat brain 'GPS' maps routes to rewards

While studying rats' ability to navigate familiar territory, Johns Hopkins scientists found that one particular brain structure uses remembered spatial information to imagine routes the rats then follow. Their discovery has ...

Epilepsy sends differentiated neurons on the run

(Medical Xpress)—The smooth operation of the brain requires a certain robustness to fluctuations in its home within the body. At the same time, its extraordinary power derives from an activity structure poised at criticality. ...
