A Functional and Structural Investigation of the Human Fronto-Basal Volitional Saccade Network
Figure 3
Single participant activation maps.
The activation patterns (T-maps) are presented for a representative participant. In the left column (A), a coronal and 2 axial slices are shown with activation during saccades in darkness vs rest in red (task 3) and antisaccades as compared to prosaccades in blue (task 1). In the right column (B) the same slices are shown again with activation for saccades in darkness vs rest in red (task 3) and visual activation during fixation vs rest in green (task 2). Activation maps are overlaid on slices from the normalized anatomical scan of the same subject. In the upper 2 slices activation in the FEF and SEF can be seen, and in the lower slice a zoomed in section of the striatum where saccade activation is observed in the putamen. MNI coordinates of the slices is given in upper right hand side of each slice (y-coordinate for coronal slice, z-coordinate for axial slices). Activation is thresholded at T = 3.5. Slices are displayed in neurological convention (left = left). Labels: SFS: superior frontal sulcus; CS: central sulcus; PUT: Putamen; CN: Caudate Nucleus.
