Neuroimaging is a rapidly growing aspect of neuroscience with lots of new toys to view the active structures of the brain during as a result of different stimuli. But this new technique takes it to a new level. There are great pictures of hippocampal neurons from the “brainbow” mouse. Stanford’s online-medical ezine has a nice [...]
