Between-group comparisons of encoding task dependent functional coupling (PPI) with the hippocampi as seeded regions.

Seeded region	Coupled region	Controls	Premutation carriers	Significance
Left hippocampus	L BA 47 (VLPFC)	0.0120	−0.2423	p = 0.037
Right hippocampus	R BA 47 (VLPFC)*	0.0419	−0.2353	p = 0.016
	R BA 46 (DLPFC)	0.1571	−0.1100	p = 0.028
	R parahippocampal gyrus*	0.2438	−0.0950	p < 0.001

Average intensity levels shown were extracted for each participant using individually non-normalized, individually traced hippocampal masks using Marsbars toolbox (Brett et al., 2002).

*Denotes significant between-group co-activation differences when corrected for multiple comparisons
