Kostas Lagogiannis recently emailed us to let us now about a June 2018 paper entailing a cheap method to monitor genetically targeted neural activity and behavior in Drosophila larvae simultaneously. The paper is written by himself, Manuela Marescotti, Barbara Webb, R. Wayne Davies and J. Douglas Armstrong
The concept is to create a high throughput substitute or complimentary technique to confocal imaging to test for neural responses to stimuli. The components for the setup are listed at the end of the Supplementary Information, and show a cost of $2500 or less (converted from British pounds), with half of the cost coming from a Photomultiplier Tube purchase. Check out the paper for the specifics and lots more science!
