Effect of eye movements on the magnitude of functional magnetic resonance imaging responses in extrastriate cortex during visual motion perception.
TL;DR: The fMRI response in V5 during pursuit is significantly enhanced, which may represent additional processing demands required for the control of eye movements and support earlier findings on a motion-specific area in lateral occipitotemporal cortex (human V5).
A randomized, double-blind, placebo-controlled study of oral hydrolytic enzymes in relapsing multiple sclerosis.
TL;DR: No treatment effect between the placebo and the HE groups was found either for clinical or MRI parameters, supported by a complete protection by HE from experimental allergic encephalomyelitis, an animal model related to MS.

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.

fMRI response during visual motion stimulation in patients with late whiplash syndrome.
TL;DR: Reduced psychophysical motion performance and reduced fMRI responses in symptomatic patients with late whiplash syndrome both point to a functional impairment in cortical areas sensitive to coherent motion.
