BC1 The Eye, the Sky and Compass Orientation
The course will cover the range of eye design across the animal kingdom, with the limitations and benefits of different type of eyes. We will then move over to information contents of the sky, that includes patterns and structures not visible to the human eye. The last two sessions will present the form and function of celestial compass systems, with a special focus on behavioural studies in the field.Objectives
Eye design across the animal kingdom, information contents of the sky and the form and function of celestial compass systems. Methods to study sensory biology and neurobiology, with a behavioural focus.Literature
