Peaks of activation for regions where activity increased as a function of exposure to the speech streams in 13-year-olds

			Increases in artificial languages (U↑ + S↑)					Increases in artificial languages > random syllables (U↑ + S↑ > R↑)
Anatomical regions	BA		x	y	z	t	k	x	y	z	t	k
Superior temporal gyrus	22	L	−42	−34	16	3.43	652
	22	R	54	−10	4	3.56	633
	42	L	−66	−20	8	3.80	652	−66	−22	8	3.77	575
	42	R	60	−20	12	3.89	633	48	−30	16	4.12	565
Middle temporal gyrus	21	L	−50	−18	−2	3.82	652	−48	−34	2	3.80	575

Note: Activity thresholded at t > 3.21 (p < .001), corrected for multiple comparisons at the cluster level (p < .05). BA refers to putative Brodmann Area; L and R refer to left and right hemispheres; x, y, and z refer to the Talairach coordinates corresponding to the left-right, anterior-posterior, and inferior-superior axes, respectively; t refers to the highest t score within a region; k refers to cluster size (note that different regions with the same cluster size are part of the same cluster).
