  • Fluorescent calcium imaging reveals the firing patterns of brain cells, but microscopy in behaving animals is challenging due to brain motion. Here, the authors develop a two-photon fluorescent microscope to record from many cells in a brain volume of freely-behaving Drosophila larvae.

  • An optogenetic illumination system based on the use of a digital micromirror device and video tracking software is reported, which allows real-time light delivery with high spatial resolution to specified targets in freely moving Caenorhabditis elegans. Also in this issue, Stirman et al. report a similar illumination system using a liquid crystal display projector. Both methods allow optogenetic perturbation of a variety of neural circuits in the behaving worm.

  • A device for generating precise spatial and temporal patterns of airborne odorants is reported. In combination with machine vision tracking software, the authors use the device to monitor navigation of freely moving Drosophila melanogaster larvae.
