High resolution fMRI has the potential to reveal brain
activity patterns in greater spatial detail, which
promises more precise localisation and the elucidation
of population-code information residing in fine-grained
columnar patterns of neuronal activity. However, there
are significant challenges of acquiring high resolution
data at 3T. In this study we compared three fMRI
resolutions (1.6mm, 2mm, and 3mm isotropic) in terms of
their decoding accuracy of checkerboard-like response
patterns in early visual cortex at different spatial
scales.
