Flexible naturalistic feature extraction in Drosophila
Abstract/Contents
- Abstract
- This dissertation summarizes original work investigating the neurobiological basis of naturalistic visual feature extraction using in vivo 2-photon voltage and calcium imaging in the Drosophila optic lobe. The first chapter is a published paper demonstrating that direction selectivity in the Drosophila dark motion pathway neuron T5 can emerge from linear input summation. The study finds evidence that an initial, linear, moderately direction selective voltage signal is transformed into a strongly direction selective calcium signal in T5. The second chapter is an unpublished project, in which a series of methods are developed to assess how presynaptic adaptations to naturalistic visual features might enable stable direction selectivity in T5.
