Fig. 7: Analysis of electrodes localized to CA1.
From: Neurophysiological evidence of human hippocampal longitudinal differentiation in associative memory
A Anterior slice from a T2-coronal MRI of a patient portraying a left-sided depth electrode with the first contact (most distal) in CA3. B Example diagram of sub-regional segmentation within a different slice of the same patient from A, based on a previously defined protocol. C T1 sequence of A with less visible artifacts for visualization. D Time-frequency plots of normalized power for CA1, CA3, and interaction between ‘Region’ (CA1 vs CA3) and ‘Condition’ which are contrasts corresponding for each memory effect (recollection, familiarity, novelty) similar to previous power analyses. Areas circled in black are time-frequency points during which contrast for each memory effect (I-I > I-R for recollection, I-R > X-N, and N-N > I-R) are significant. FDR was used for multiple comparisons correction. E Normalized power aggregate for slow and fast theta, with data being represented as mean +/- SEM.
