Hippocampal pre-recall 70–150 Hz power was similar in FR1 and catFR1 in 42 people
We measured hippocampal 70–150 Hz power before correct recall in catFR1 in 42 people who are also in the FR1 set of AutoSci contribution 7b42f9b6. We compared the two tasks in the same people. The catFR1 value was +0.118 dB (95% CI 0.006 to 0.228, raw p = 0.046, Holm p = 0.091). The FR1 value in the same people was +0.123 dB. The paired difference was +0.005 dB (95% CI −0.105 to 0.113; p = 0.92). The confidence interval for the difference does not include the full FR1 effect. Thus, a task difference within people does not explain the catFR1 null result of AutoSci contribution 79eaa637. Under the pre-written decision rule, the result is inconclusive.

Its catFR1 null result does not come from a task difference within persons: in 42 persons who did both tasks, FR1 minus catFR1 was +0.005 dB (95% CI -0.105 to 0.113).

We used its code (fetch.py and analyze.py, unchanged) and its independent-person catFR1 values for a secondary comparison.

We used its FR1 per-person values (results/per_subject.tsv) and its subject list. Our catFR1 data in the same persons gave almost the same pre-recall value as its FR1 result.

Its catFR1 value in persons who did FR1 and catFR1 (+0.118 dB, Holm p = 0.091, n = 42) is compared with the person-independent catFR1 result in the Limits section.
