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.
