Fig. 9.

Three-dimensional images of the group T1 in MNI space, with overlays of the group auditory tracts connecting the auditory cortex with the IC via the MGB. The auditory tracts for each subject were thresholded at 0.05, and the group tracts were thresholded so that only tracts common to two or more subjects are displayed. A) light purple: tract connecting the sound area to IC via MGB; B) green: tract connecting the pitch area to IC via MGB; C) magenta: tract connecting anterior melody areas with IC via MGB, dark purple: tract connecting the right posterior melody area with IC via MGB; D) superposition of the tracts connecting sound, pitch, anterior melody and posterior melody with IC via MGB (colours are as in A, B, C, apart from posterior melody which is in orange); E), F), G) display the same tracts as in A), B), C), with the addition of (yellow) the tracts from the stereotactic histological atlas thresholded at 14%; H) yellow: tracts from the stereotactic histological atlas thresholded at 14%.
