A motion vision system for a Martian Micro-Rover
This thesis describes a monocular, motion vision system that was designed to meet the size, power, and processing constraints of a small, robotic, planetary explorer. The computational requirements of the brightness gradient approach, which is commonly used in motion vision systems, were found to …

Using new tools to study the neural mechanisms of sensation: Auditory processing in locusts and translational motion vision in flies
… the speed sensitivity of Drosophila for apparent motion during flight. I also developed a flexible approach to presenting optic flow scenes for functional imaging of motion-sensitive neurons. Finally, through the on-line analysis of behavioral measures, image rendering, and display streaming with …

Feedback control of analog neurons and shunting inhibition in dendrites for bio-inspired neuromorphic systems.
… This research revisits the original vision of neuromorphic computing by focusing on analog circuit implementations that closely emulate biological neural mechanisms. The work explores a tuning approach for analog neuron circuits based on the Izhikevich model and advances the use of …

Case Studies in Invertebrate Visual Processing: I. Spectral and Spatial Processing in the Early Visual System of Drosophila melanogaster II. Binocular Stereopsis in Sepia officinalis
… has emerged as a key model for invertebrate vision research. Despite extensive characterisation of motion vision, very little is known about how flies process colour information, or how the spectral content of light affects other visual modalities. With the aim to accurately dissect the …

The Influence of Spatial Attention on Neuronal Receptive Field Structure within Macaque Area MT
Der Einfluss von räumlicher Aufmerksamkeit auf die Struktur rezeptiver Felder im superior-temporalen Kortex des RhesusaffenSelektive Aufmerksamkeit führt zu einer multiplikativen Verstärkung von Einzellzellaktivität im sensorischen Cortex. Modulation durch Aufmerksamkeit ist besonders ausgeprägt, …
