Abstract

Here we propose to use ultra-high-field (9.4T) human fMRI in order to answer two questions: firstly, is there a differential involvement of cortical layers in the processing of retinal motion and of objective motion in high-level visual areas? Second: is there a columnar organisation segregating retinal and objective motion processing? A differential laminar response profile to the two motion types would provide important cues with regards to the hierarchy of processing involved in different areas, with modulation of upper, middle, or lower layers speaking for feedback, bottom-up or output sources of the different signals, respectively. A columnar segregation would indicate specialized and segregated circuits within a given area.
