Visually Guided Behaviours
visually guided behaviours
Vision outside of the visual system (in Drosophila)
We seek to understand the control of behavior – by animals, their brains, and their neurons. Reiser and his team are focused on the fly visual system, using modern methods from the Drosophila toolkit to understand how visual pathways are involved in specific behaviors. Due to the recent connectomics explosion, they now study the brain-wide networks organizing visual information for behavior control. The team combines explorations of visually guided behaviors with functional investigations of specific cell types throughout the fly brain. The Reiser lab actively develops and disseminates new methods and instruments enabling increasingly precise quantification of animal behavior.
Understanding the visual demands of underwater habitats for aquatic animals used in neuroscience research
Zebrafish and cichlids are popular models in visual neuroscience, due to their amenability to advanced research tools and their diverse set of visually guided behaviours. It is often asserted that animals’ neural systems are adapted to the statistical regularities in their natural environments, but relatively little is known about the visual spatiotemporal features in the underwater habitats that nurtured these fish. To address this gap, we have embarked on an examination of underwater habitats in northeastern India and Lake Tanganyika (Zambia), where zebrafish and cichlids are native. In this talk, we will describe the methods used to conduct a series of field measurements and generate a large and diverse dataset of these underwater habitats. We will present preliminary results suggesting that the demands for visually-guided navigation differ between these underwater habitats and the terrestrial habitats characteristic of other model species.
