MRI T2 relaxation times (lower values are thought to indicate greater rCBV) for the left and for right hemispheres as well as the laterality indices calculated from these values for subjects who by probe AEP had a left or a right negative hemispheric emotional valence.

Probe AEPs	N	LH	RH	LI (L-R/L+R)
Left Negative HEV	10	87.23 ± 7.51	87.56 ± 7.76	-0.366 ± 0.451
Right Negative HEV	17	89.88 ± 9.72	89.78 ± 9.54	0.089 ± 0.586*

LH = left hemisphere

RH = right hemisphere

* unpaired t-test Left – Right Negative HEV:t = 2.11, df = 25, p = 0.045.
