Against hyperacuity in brain reading: Spatial smoothing does not hurt multivariate fMRI analyses?
Recently it has been suggested that multivariate analyses of functional magnetic resonance imaging (fMRI) data can detect high spatial frequency components of cortical signals, like sub-millimeter columns. This 'hyperacuity' seems to be at odds with the common assumption that the fMRI signal has a low spatial resolution due to the spatial spread of the underlying hemodynamic events. To resolve ...
متن کاملAdaptive spatial smoothing of fMRI images
It is common practice to spatially smooth fMRI data prior to statistical analysis and a number of different smoothing techniques have been proposed (e.g., Gaussian kernel filters, wavelets, and prolate spheroidal wave functions). A common theme in all these methods is that the extent of smoothing is chosen independently of the data, and is assumed to be equal across the image. This can lead to ...
متن کاملDoes rejection hurt? An FMRI study of social exclusion.
A neuroimaging study examined the neural correlates of social exclusion and tested the hypothesis that the brain bases of social pain are similar to those of physical pain. Participants were scanned while playing a virtual ball-tossing game in which they were ultimately excluded. Paralleling results from physical pain studies, the anterior cingulate cortex (ACC) was more active during exclusion...
متن کاملSpatial smoothing in fMRI using prolate spheroidal wave functions.
The acquisition of functional magnetic resonance imaging (fMRI) data in a finite subset of k-space produces ring-artifacts and 'side lobes' that distort the image. In this article, we explore the consequences of this problem for functional imaging studies, which can be considerable, and propose a solution. The truncation of k-space is mathematically equivalent to convolving the underlying "true...
متن کاملWhat Does Pain Hurt?
Anxiety and Chronic Pain Opioids in Cancer Pain Coping with Pain “Thank you for giving me my life back.” Through frustration and failure, the promise of hearing these words sustains those who treat pain sufferers. The first time I heard them I felt great pride. With time, however, I came to understand that my efforts and my patients’ gratitude were manifestations of a much larger process. This ...
