A new method developed at Janelia enables researchers to count the individual molecules contained in a single spot of light detected by a fluorescence microscope—a quantity important for understanding...

Researchers at HHMI’s Janelia Research Campus are decoding how neurons carry out computations carefully calibrated to an animal’s movement and environment to precisely regulate the release of neuromod...

To see how cognitive maps form in the brain, researchers used a Janelia-designed, high-resolution microscope with a large field of view to image neural activity in thousands of neurons in the
