Abstract

fetched live from OpenAlex

Local field potentials (LFPs) are electrophysiological signals with a wide range of amplitude variations from 10 μV to 1 mV, depending on several factors including electrode placement, recording depth, number and sign of brain sources contribution, brain tissue properties, etc. In this paper, the design of an adaptive gain-adjustable LFP sensing device is proposed. The device can cope with a wide range of LFP signal amplitude variations over different individuals, or over long-term chronic use in one specific subject. This LFP neural sensing device is capable of 50-100 dB dynamic gain amplification by detecting the LFP initial level (10 μ V - 1 mV). It is also miniature, light-weight, and cost effective, suitable for pre-clinical neuroscience research. The performance of the device has been successfully validated using bench-top experiments by using AC, and pre-recorded neural signals, under fixed-gain and adaptable-gain settings.

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.

Not 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.
