Fig. 4: Development of lateralized tutor-selective responses.
From: Tracing development of song memory with fMRI in zebra finches after a second tutoring experience
Illustrations (top) of the activated cluster (blue) and mirrored (red) regions of interest for the lateralization analysis overlaid on coronal sections of the zebra finch MRI atlas. Estimates of differential processing (bottom) of TUT1 songs in (a) control birds (% signal change: TUT > NOV), and (b) TUT2 songs in sequentially tutored birds (% signal change: TUT2 > TUT1) in the left and right midbrain. The regions of interest for calculating percent signal change were based on the activated clusters for TUT > NOV in Fig. 3f and TUT2 > TUT1 in Fig. 3a. Boxplots showing the interquartile range (box), median (black line), and 1st and 3rd quartile; all birds are represented by circles (control: N = 13, sequentially tutored: N = 15). Paired two-tailed t tests were performed, *P < 0.05 between left and right hemispheres.
