3D footage of nematode brains links - video 2

This film—shown in quarter-time—shows the four simultaneous video feeds that the Princeton researchers used to capture the nematodes' neural activity. The upper left panel shows the position of the nuclei in all the neurons in an animal's brain, while the upper right panel recorded neural activity indicated by a fluorescent calcium indicator. The lower left panel shows the animal's posture on the microscope plate, which automatically adjusted to keep the animal within the cameras' view. At bottom right is a low-magnification fluorescent image of a nematode brain, which contains 302 neurons. (Video courtesy of Andrew Leifer, Lewis-Sigler Institute for Integrative Genomics)
