Neural synchrony-monitoring wireless brain implant for intractable epilepsy neuromodulation
Bibliographic record
Abstract
A validation of a closed-loop system-on-chip (SoC) for epilepsy treatment is presented. A 12mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> 0.13μm CMOS SoC provides the functionality of neural recording, neural stimulation and early seizure detection based on the bivariate phase synchrony estimation algorithm. The SoC can operate in a closed loop, has 64 neural recording and 64 neural stimulation channels, and dissipates 1.4mW and 1.5mW across 64 channels for neural recording and stimulation, respectively. Two in vivo experiments with freely moving rats based on a non-convulsive and convulsive seizure model are presented. The first in vivo experiment validates the results by comparing the output of the SoC with a SIMULINK model of the implant. The second in vivo experiment validates the SoC in early seizure detection and as a closed-loop intractable epilepsy treatment with 80 percent efficacy. Long Evans rats are used for all experiments. All data are cross-validated by a conventional benchtop amplifier.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
