We work to understand the neural computations that underlie visual perception by measuring detection and discrimination of carefully specified stimuli.

Perception lab dr hannah smithson

How are the signals from the three classes of cone photoreceptors processed to give rise to our perceptions of colour? What are the neural circuits of comparison and combination that permit the efficient transmission of visual information from retina to cortex? We specialize in psychophysical experiments with adult observers, but collaborate with physiologists, computer scientists and physicists to inform and constrain our analysis of behavioural data.
