Researchers discover neuronal mechanism linked to a minutes-long decision process in fruitflies RockefellerUniv nature
lower_sucroselast_higher_sucrosesuggesting that flies are not taking a shortcut—and thus not manifesting use of spatial information—at the end of the search. It is possible that flies use spatial information to guide the search in conditions with visible landmarks or where they perform less thigmotaxis ; our flies largely edge-hugged as they traversed the chamber. All experiments in this study were conducted in darkness.
Extended Data Fig. 8 Changes in oviDN ∆F/F during substrate transitions are not due to consistent, detectable, changes in behavior., We detected substrate crossing moments on the egg-laying wheel, and aligned behavioral data to these moments: 2459 and 2460 traces from 70 cells in 53 flies . Plotted here is the probability that a fly’s centroid is located > 2 mm away from the boundary between two substrates , as a function of time from the substrate crossing . For a 2.
