Fly brain navigation goal maintained by normalization, not selection

By PulseAugur Editorial · [1 sources] ·

A new research paper explores how the fly brain maintains a single goal for navigation. The study, based on the FlyWire connectome, suggests that the FC2 neurons normalize an externally set goal rather than actively selecting it through a winner-take-all mechanism. This normalization is primarily achieved by FB5A cells, which provide global inhibition to FC2 neurons. AI

IMPACT Provides insights into biological neural computation, potentially informing future AI architectures for goal-directed behavior.

    How the fly holds a single goal: normalization, not selection, in Drosophila FC2

    A walking fly steers toward a goal direction, held as a bump of activity across the FC2 neurons of the fan-shaped body. These neurons also inhibit one another over distance, more strongly the farther apart they are, a feedback proposed to keep the fly on a single goal. We asked, …
