Nerve Cells in Cortex (IMAGE) Max-Planck-Gesellschaft Caption This image shows the same deep layer V brain cells (red box) labeled with the genetically encoded fluorescent marker, but actually imaged noninvasively from a living animal using a modified multi-photon microscope, or RAMM approach. This allows scientists to study activity in neuronal populations deep in the cortex of an awake behaving animal and will lead to a deeper understanding of how cortical networks perform computations.
