Roles and representations for visual motion
Tuesday 21 June @ 4 pm – 5:30 pm (Le Gros Clark Lecture Theatre)
Sam Solomon from UCL will speak about how motion is represented in marmosets and mice. His work uses large-scale multi-electrode recordings to investigate neural networks at each level of the visual pathway. He is particularly interested in how sensory signals interact with internal representations and model systems that can be developed using our knowledge of the visual system.
Motion analysis is an important feature of visual processing in all species. In this presentation I will outline two independent streams of work in our laboratory that ask how visual motion is analysed, and how motion might be used to guide behaviour. In the first part I will describe experiments in which we have used large-scale multielectrode recordings to ask how populations of neurons in marmoset area MT – an area known to be important in primate motion vision – help represent the moving objects and textures. In the second part I will describe behavioural experiments in mice in which we have asked how visual motion helps guide the selection of instinctive (unconditioned) behaviours.
