Abstract Visual system is one of the most complicated processing architectures in the brain. Consequently, more neurons are devoted to vision than to any other sensory function in most vertebrates and invertebrates. Insect brain models have been used extensively to understand the underlying basic mechanisms in more complex systems. With approximately 10^6 neurons, the insect brain is much simpler than that of primates, who have roughly 10^11 neurons. This is also true for the insect visual system as compared to the primate visual system. The advent of microtechnology and sophisticated recording interfaces has made it possible to perform live recording to investigate higher-order (mammalian) brains and extract precise information. This technology can now aptly be scaled-down to perform visual recordings from invertebrates. Besides miniaturization, the other requirement for performing insect-scale measurements is biocompatibility of the implant material which can evade immune response and promote neuronal growth. The goal of this project will be to develop a fully implantable recording interface, and record from live insect ommatidia during visual stimulation. This project paves the way for a new developmental neuroengineering platform which will enable in-vivo investigation during developmental life cycle. The results obtained will also be directly significant to insect visual processing research which has broader applications in areas such as micro air vehicles and neuromorphic visual processing chips.
