Design of flexible polyimide electrodes for a Wireless Infrared EEG Recorder for chicken embryos
Bibliographic record
Abstract
The study of the emergence of sleep and waking \nduring embryonic life forms a fundamental part of \nunderstanding sleep physiology. Electroencephalography \n(EEG) is one of the most basic tools used to investigate sleep. \nWe describe the preliminary design of a telemetry system \ncomposed of conductive polymer electrodes connected to a \ntransmitter and a receiver. As an additional benefit, the system \nis electromagnetically compatible with Positron Emission \nTomography (PET) scanners, permitting the simultaneous \nacquisition of PET images and EEG data. The system was \ndeveloped for recording chicken embryo EEG signals. \nElectromagnetic interference is avoided using an infrared data \nlink for communication. The system makes use of six \nconductive polymer electrodes, with dimensions on a \nmicrometer scale, connected via a ZIF (Zero Insertion Force) \nconnector to a small, low power IR transmitter. This \ntransmitter is optically coupled to a receiver, that it is \nconnected to a PC for signal processing and data storage.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
