The New Cajal Era

More than 100 years have passed after the first contributions made by Santiago Ramón y Cajal to the neural network theory. Nowadays neuroscientists take advantage of innovative tools to study neural circuits in order to understand complex behaviours.

This image by David D’Amico, from the group on neurobehavioral phenotyping of mouse models of disease at the CRG, shows the hippocampus of a transgenic mouse expressing yellow fluorescent protein (YFP) in specific subsets of central neurons. This type of tansgenic mice help scientists to understand neural networks in both physiological and pathological conditions.
