Serial correlations in single-subject fMRI with sub-second TR
When performing statistical analysis of single-subject fMRI data, serial correlations need to
be taken into account to allow for valid inference. Otherwise, the variability in the parameter …

Measuring the effects of attention to individual fingertips in somatosensory cortex using ultra-high field (7T) fMRI
Attention to sensory information has been shown to modulate the neuronal processing of
that information. For example, visuospatial attention acts by modulating responses at …

Using multi-echo simultaneous multi-slice (SMS) EPI to improve functional MRI of the subcortical nuclei of the basal ganglia at ultra-high field (7T)
The nuclei of the basal ganglia pose a special problem for functional MRI, especially at ultra-high
field, because T2* variations between different regions result in suboptimal BOLD …
