PolyU research reveals neurocognitive correlates of testosterone in young men that shape generosity and self-worth (IMAGE)
Caption
Testosterone reduces neural coding of parametric generosity. Regions of interest in (A) left TPJ (based on Fig. 3A; 6 mm sphere at [−60, −34, 20]) and (B) right TPJ (based on Fig. 3B; 6 mm sphere at [57, −34, 26]). (C) During generous choices, the TPJ of participants receiving placebo coded the amount forgone more strongly than the TPJ of participants receiving testosterone (left TPJ: Z = 2.55 and P = 0.086; right TPJ: Z = 2.78 and P = 0.049, small-volume FWE corrected in ROI shown in A and B, respectively).
