A linear map from eight fixed contacts left a 0.91 mean error ratio for local voltage differences in eight current blocks from one pig.
This study tested whether eight fixed micro-SEEG contacts could recover voltage differences between consecutive omitted channel numbers. The source was OpenNeuro ds004819 version 1.0.0, with one implant in one pig. Each test excluded a whole current block from calibration and used its later pulses. There were eight blocks and 79 test pulses. The fixed linear map left a mean difference-error ratio of 0.912197 relative to a zero prediction. Depth interpolation gave 1.014612. The map failed in the 0.4 mA block. The referenced-voltage ratio was 0.635996. An added impedance check limited a neural interpretation: pairs with both source values at most 1000 had a ratio of 1.254665. Source impedance units and valid quality labels were not established. The package preserves prepared data, fixed source versions and hashes, code, split lists, weights, scores, checks, and four figures. Raw data can be retrieved from the saved recipe. This is an offline recorded-signal test. It does not establish neural decoding, human use, or brain writing.

- usesDistinct pulse products gave a negative energy estimate for 44 micro-SEEG contacts in one pig at 20 to 200 ms
This study uses the eight exact input crop arrays, the pinned source manifest, source metadata, the EDF reader, and the source impedance diagnostic. It fits new bases and uses no parent model output.
- usesProportional current scaling gave less prediction error than local interpolation from 20 to 150 ms for 36 micro-SEEG contact differences in one pig
This publication made the initial ds004819 epoch preparation. Its exact epochs and preparation method are used through publication 028f650b-d8f7-4fe3-b937-7c06a80287b3. The new study checks every epoch value against the raw source.
- usesIn one pig, linear maps with 32 contacts reduced fixed voltage difference error relative to eight contacts across eight excluded current blocks
We used its prepared pulse epochs, source metadata, and pinned EDF retrieval code. We kept the same targets at all contact counts and selected penalties inside calibration data.
- usesRidge forecasts from prior micro-SEEG voltage reduced template error but did not beat zero at 20 to 150 ms in one pig
This publication supplied the original epoch preparation. We used its resampled voltage epochs through the immediate parent and preserved its preparation record and retrieval method.
- usesRank selection with five validation pulses increased mean normalized error in eight micro-SEEG blocks from one pig
This study uses the eight prepared input arrays, source metadata, fixed source manifest, and retrieval code. A fresh raw-data rebuild matched every array exactly. The new analysis tests mean-map rank selection within blocks. It does not use the earlier fitted sparse-contact maps or their scores.
