The Processing of First- and Second-Order Motion in Human Visual Cortex Assessed by Functional Magnetic Resonance Imaging (fMRI)
TL;DR: The results are consistent with the hypothesis that first-order motion sensitivity arises in V1, that second- order motion is first represented explicitly in V3 and VP, and that V5 (and perhaps also V3A and V3B) is involved in further processing of motion information, including the integration of motion signals of the two types.
Spiral reconstruction by regridding to a large rectilinear matrix: a practical solution for routine systems.
TL;DR: A simple way to implement a spiral reconstruction algorithm is described that avoids the data interpolation required by gridding approaches commonly used and thus allows the introduction of spiral imaging to routine scanners.

An fMRI Investigation of a Patient with Cerebral Achromatopsia: Evidence for a Role of Chromatic Extrastriate Mechanisms in Motion Encoding:
TL;DR: It is concluded that colour information can activate (or modulate the activity of) motion-specific mechanisms usually thought to be colour-blind, and has implications both for the understanding of unconscious information processing in vision, and for considerations of neural efficiency when encoding redundant image information.

Higher-order motion perception in human visual cortex: evidence from fMRI
TL;DR: fMRI was used to investigate human visual cortex responses to higher-order motion stimuli, and a more pronounced activation of area MST/V5a (BA37/39) was found in response to the structure-from-motion stimulus, compared with random motion.
