    FIGURE 1. A typical neuron, with extensions to the cell body, is shown in its presynaptic state. The region where an axon terminal/ending communicates with its postsynaptic target cell is known as a synapse.
    High-performance sensors, lenses, and light modules are enabling an unprecedented ability to image action potentials. Building a system to capture these important event triggers...

    FIGURE 1. The ms-TRFS experimental configuration includes optical pass-band filters with center wavelength/bandwidth: 390/40, 452/45, 542/50, 629/53 nm, respectively (F1 to F4). BS1 to BS4 are dichroic beamsplitters with greater than 93% transmittance for wavelengths longer than 360, 420, 510, and 590 nm, respectively. The system also includes a wavelength selection module, multimode fiber-optic delay lines, and fluorescence detection components. All elements of the fiber selection module are mounted on a compact, 36 × 165 mm breadboard. A FLIm image results from an x-y scan.
    Time-resolved ("lifetime") fluorescence spectroscopy and imaging provide label-free optical molecular contrast of diseased tissues and outperform steady-state fluorescence. Now...
