fMRI and high-field imaging, visual symmetry, visual neuroscience
I am currently working on a project investigating processing of visual symmetry in the human brain as part of the ESRC funded project “When does perceptual organisation happen?”. Symmetry is a pervasive aspect of the environment we live in and can be observed at different scales in nature and artificial settings. The abundance and relevance of this feature is reflected in a selectivity for processing visual symmetry in the brain. This work draws on previous imaging studies suggesting the involvement of a distributed network of brain areas in extrastriate and higher visual cortex in symmetry processing. The aim is multifaceted: on the one hand looking at how pattern representation of visual symmetry is organised along the visual pathway, how this neural representation is modulated by selectively attending to relevant or irrelevant symmetry features, and how different types of symmetry (e.g., reflection vs. rotation) are represented in the brain.
I am also broadly interested in high-field imaging and multimodal imaging techniques as tools to combine multiple measurement types describing complex systems such as the brain, with the aim of bridging across modalities and spatial scales.
