Fig. 2: Hippocampal power differences during associative recognition.
From: Neurophysiological evidence of human hippocampal longitudinal differentiation in associative memory
A Time-frequency plots depicting normalized power between anterior hippocampus (AH) and posterior hippocampus (PH) with interaction effects from model estimates. Recollection, familiarity, and novelty effects are represented with I-I, I-R, and N-N items, respectively. Highlighted regions in black are time-frequency points that significantly differ in the corresponding contrast (I-I > I-R for recollection, I-R > X-N (complete misses) for familiarity, and N-N > I-R for novelty) using LMEM with FDR correction. The highlighted red pixels in the interaction plots represent time-frequency points during which there is significant region-contrast interaction (FDR), while the colors represent the main regional contributions (i.e., dark areas represent posterior > anterior, while bright areas represent anterior > posterior). B Aggregation of normalized power (I-I for recollection, I-R for familiarity, N-N for novelty) in plot A across slow (2–5 Hz) and fast (5–9 Hz) theta. Standard errors of normalized power across electrodes are shown as shading bands surrounding each line, which represents data mean. Significant longitudinal differences for each contrast from A were highlighted for each band.
