Fig. 3: Effect of prolonged maternal presence on the grey matter concentration in the equine brain (with mother > without mother).

Sagittal and axial brain slices showing differences in grey matter concentration (GMC) between groups. The orange dashed lines represent the approximate positions of axial brain slices. The data were obtained from SPM unpaired two-sample t test analysis using a voxel-level threshold p < 0.05, t threshold (dof = 21) = 3.4414, two-tailed, FDR corrected, and a voxel threshold = 6.000. amyg: amygdala, hippo: hippocampus, hypo: hypothalamus, ins: insula, mCC: medial cingulate cortex, thal: thalamus.
