Visuomotor functional MRI Study: Time-resolved single-trial fMRI was acquired in visual and motor areas during a "single" visually instructed, delayed motor task. Activation was observed first at visual areas, and later at motor areas.

Intrinsic optical imaging (movie): High spatial and temporal resolution brain mapping can be achieved by continuously obtaining digital video Public/Images. Orientation-selective functional maps were determined. Dimension of image is 6.6 mm in a horizontal (lateral-medial) direction and 8.8 mm in a vertical (anterior-posterior) direction. Dark or bright lines indicate pial vessels. Dark patches indicate activation sites corresponding to the stimulus with the specific orientation. When the orientation of stimuli was changed (see a bar in the left corner in the movie), the preferred orientations change smoothly, forming a “map” of orientation selectivity. The continuity of orientation preferences is interrupted only at the singular points (termed orientation “pinwheels”) where the domains for all orientations converge. Click here to view the movie.
