My current research focus is on neural aspects of perception for action using fMRI. This work is in collaboration with David Field at Reading University and Richard Wilkie at the University of Leeds. In a recently completed study we looked at the neural correlates of using future path information in order to anticipate changes in heading perception. We found that whilst the human motion complex (MT+) was activated for detecting current heading (using near road stimuli), a region of superior parietal lobe was specifically involved detecting future path (using far road stimuli) for the purpose of anticipating heading direction and thus improving performance (Billington, Field, Wilkie, & Wann, In Press). More recently we have investigated looming detection and timing computation, with the aim of replicating previous findings in rodent and avian species which implicate the potential involvement of human superior colliculus and pulvinar nucleus of the thalamus in detecting stimuli on a collision course with the observer.
