Topic: large-field neurons

The apparent motion of features in a visual scene — optic flow — provides rich information about the animal’s self-motion and its environment [Gibson 1950]. An animal estimates the optic flow with motion sensitive neurons. In flies, the T4/T5 neurons encode small-field directional motion signals by sampling neighboring eye facets. The signals are then integrated by large-field neurons, which are tuned to complex global patterns of optic flow. Are these patterns simply inherited from their T4/5 inputs or synthesized by a more complex computation? Near the center of the eye, the 4 T4 subtypes ha
