Purpose: Estimation of uncertainty of MAP-MRI metrics is an important topic, for several reasons. Bootstrap derived uncertainty, such as the standard deviation, provides valuable information, and can be incorporated in MAP-MRI studies to provide more extensive insight. Methods: In this paper, the uncertainty of different MAPMRI metrics was quantified by estimating the empirical distributions using […]

Event-related fMRI have been widely used in locating brain regions that respond to specific tasks. However, activities of brain regions which modulate or indirectly participate in the response to a specific task are not event-related. Event-related fMRI can’t locate these regulatory regions, detrimental to the integrity of the result that event-related fMRI revealed. Direct-current EEG […]

Can we represent number approximately? A seductive reductionist notion is that participants in number tasks rely on continuous extent cues (e.g., area) and therefore that the representations underlying performance lack numerical content. I suggest that this notion embraces a misconception: that perceptual input determines conceptual content. Read Full Article (External Site) Dr. David LowemannDr. David […]
