Research Summary
Within the daily experience of our lives, a significant amount of our behaviour remains visually-driven. We use visual landmarks to guide our navigational strategies, we rely on visual cues to find our friend in a crowd of passers-by and even when communicating our thoughts, many of the descriptors we use are of visual character. However, while the sensory input we receive within the modality might at first appear consistent across our visual experience, the distributional characteristics of visual features across space are far from uniform.
I am interested in the relationship between coarse-scale organisational principles of visually-driven areas in the human brain (e.g. visual cortex, superior colliculus) and the distributional characteristics of the visual environment (e.g. orientation, spatial frequency content). My work focuses on the use of computational modelling and high-field fMRI (7T) to explore:
- How sensitivity to e.g. orientation of a stimulus could be captured at the level of a single voxel and whether these sensitivities are systematically organised across the visual cortex
- How the presence of visual anisotropies (e.g. differences in receptive field size across upper and lower visual fields) is preserved across the visual system hierarchy, progressing from superior colliculus to higher-order visual areas
