Live calcium imaging and miniature microscopy

Understanding the brain in action. It's a daunting task, but technological innovations are allowing scientist to get very close. 

With EthoVision XT, PhenoTyper, and miniaturized microscopy such as nVista (Inscopix), it is possible to acquire neural activity (calcium imaging) and behavioral data in freely moving rats and mice.
