Abstract
Cortical organization is often modelled as hierarchical, modular, and relatively invariant. However, the experimental paradigms informing such models often use artificial, temporally constrained, and sensorily impoverished stimuli. In this project, the student will evaluate more distributed and context-dependent models of cortical function using the novel MOVIE II hypermodal dataset, where individuals undergo high temporal and spatial resolution functional MRI while watching a full-length movie; each individual’s sensory and myelination maps are also acquired. The student will also run further targeted EEG and fMRI paradigms on a subset of the MOVIE II cohort to follow up on specific hypotheses.
