Zebrafish 3D seizure imaging with adaptive light‑sheet

Overview

Researchers at the University of Georgia reported the development of an adaptive light‑sheet microscopy platform capable of real‑time, three‑dimensional brain imaging during seizures. The initial description highlighted the system’s electrically tunable lens, sensorless adaptive optics, and ability to acquire volumes of up to 499 × 499 × 150 µm at four volumes per second, enabling observation of seizure onset in larval zebrafish and comparison between normal and gad1b‑mutant fish.

A week later the team announced the capture of the first continuous 3‑D footage of an epileptic seizure in a zebrafish larva. The upgraded setup reduced exposure, improved optical correction, and recorded a full volume in roughly 0.25 seconds—seven times faster than earlier versions—producing 600 uninterrupted 3‑D frames over two and a half minutes. The imaging revealed seizure activity beginning in the hindbrain and propagating forward, further elucidating the role of the gad1b gene in seizure dynamics.
