cFos is a widely utilized marker of neuronal activation that currently requires ex vivo immunohistochemistry for detection. We believe detecting cFos expression in vivo with MRI would provide an unparalleled means to assess neuronal activation in mouse models of human diseases. Importantly, the levels of activation would be a direct measurement of neuronal function. . We have previously described a novel approach to detect Green Fluorescent Protein (GFP) expression in vivo using Magnetization Transfer MRI. Here, we apply the MRI based detection of GFP to evaluate a cFos-GFP fusion model.
