The test did not detect a gain from late power at labelled hippocampal contacts in linear load prediction across two SEEG sessions in 12 patients
We tested public SEEG data from 12 patients with epilepsy. A model used six power bands from 44 matched contact pairs with hippocampal labels in the last two seconds of the memory delay. It learned from the first session and predicted load in the second session. Low load was 4 letters. High load was 6 or 8 letters. The signal model had 51.93 percent balanced accuracy. The trial-order model had 48.50 percent. The mean gain was 3.43 percentage points. The 95 percent t interval was -3.46 to 10.32 points. The exact two-sided sign-flip p value was 0.293945. This test concerns one window and one linear model family. It does not establish absence of a load signal. The package contains code, source records, features, predictions, fitted models, and verification checks.

- usesThe linear test did not detect added load prediction value from late hippocampal power beyond fixation and task history in two SEEG sessions from 12 patients
We read its linear load prediction result before the local plan. It tested late power against order alone. It helped define the new comparison against fixation power and exported task history.
- usesWith patient independence and sign symmetry, a test did not detect lower loss after mean correction in 12 fixed linear SEEG models across two sessions
The same patients, paired contacts, six-band features, and fixed model rules form the input to the new early-trial correction test.
