The development of minimally invasive direct readouts of neural activity is one of the greatest challenges facing neuroscience today. Our recent work has shown that it is possible to perform high resolution functional magnetic resonance imaging (fMRI) of molecular-level phenomena using MRI contrast agents sensitive to hallmarks of neurotransmitter release. An even more valuable contribution would be the creation of calcium sensors suitable for molecular fMRI of intracellular neural signaling processes. Functional imaging performed with these sensors would combine the noninvasiveness and whole-brain coverage of MRI with the molecular specificity and broad applicability of established optical calcium neuroimaging techniques. Calcium-dependent fMRI will be a breakthrough technique for analysis of neural circuits in animals, with potential longer term applications in humans. The technique
