Mechanisms for Visual Detection of Small Targets in Insects

Abstract

The grantee investigated insect visual detection of small targets against a cluttered, moving background. The work focused on deducing neural mechanisms that underlie this ability, to an understanding of the computational principles. Electrophysiology examined the complex function of small-target sensitive neurons. Experiments explored the receptive field properties and underlying mechanisms involved in target detection, suggested the form of computational models, and focused anatomical investigations. Conceptual models were translated into numerical models that can be evaluated in simulations under a variety of conditions and compared with biological systems.
