(Phys.org) —A dye-based imaging technique known as two-photon microscopy can produce pictures of active neural structures in much finer detail than functional magnetic resonance imaging, or fMRI, but it requires powerful and expensive lasers. Now, a research team at the University of Pennsylvania has developed a new kind of dye that could reduce the cost of the technique by several orders of magnitude.
