Hippocampal dentation: Structural variation and its association with episodic memory in healthy adults

Abstract: While the hippocampus has long been identified as a structure integral to memory, the relationship between morphology and function has yet to be fully explained. We present an analysis of hippocampal dentation, a morphological feature previously unexplored in regard to its relationship with episodic memory. “Hippocampal dentation” in this case refers to surface convolutions, primarily present in the CA1/subiculum on the inferior aspect of the hippocampus. Hippocampal dentation was visualized using ultra-high r… Show more

“…Participants identified themselves as men (n=29), women (n=36), and other (n=1). G*Power 3.1 software was used to calculate a sensitivity power analysis: given our sample of n = 66, we had a power of 0.997 to observe a correlation of r = 0.51 (the strength of the relationship between dentations and episodic memory by Beattie et al, 2017) using a confirmatory one-tailed test. We also had an 80% chance of confirming any medium-sized effect of r = 0.30 or larger.…”

“…Direct labeling performance by raters was evaluated using total quantity of dentations, and was found to be very high, ICC = 0.924. Holistic assessment performance by raters was assessed using overall scores for each participant (taken as a sum across hemispheres, following Beattie et al, 2017) and was also very high, ICC = 0.921.…”
