Variable	Mean difference (TBI vs. Controls)	t (1,46)	p
L Amygdala	− 134.38	− 1.26	ns
R Amygdala	− 260.63	− 2.45	< 0.05
L Hippocampus	− 415.62	− 2.15	< 0.05
R Hippocampus	− 672.31	− 2.95	< 0.01
L Thalamus	− 914.87	− 2.20	< 0.05
R Thalamus	− 1128.75	− 2.72	< 0.01
SCL	− 2.69	− 3.51	< 0.01
BEES	− 15.58	− 1.94	< 0.05a
IRI PDS	1.08	0.69	ns
IRI ECS	− 0.71	− 0.54	ns

Notes. SCL = skin conductance level; L = left; R = right; BEES = Balanced Emotional Empathy Scale; IRI = Interpersonal Reactivity Index; PDS = Personal Distress Subscale; ECS = Empathic Concern Subscale.
