Figure 3. Comparisons of volumes of neuroimaging regions of interest across SPE profiles. Participants are also distinguished by ApoE ε4 carriers (black lines) and non-carriers (grey lines), and, where applicable, right (solid lines) and left hemispheres (dashed lines). (A) Frontal lobe GM volumes. (B) Temporal lobe GM volumes. (C) Hippocampal volumes. (D) Periventricular WMH volumes. Abbreviations: ApoE ε4: apolipoprotein ε4 allele expression; GM: grey matter; pvWMH: periventricular white matter hyperintensities; SPE: serial position effect; WMH: white matter hyperintensities.
