Abstract
Intravital studies of cellular morphology in structures such as the hypothalamus are challenging because of their location at the bottom of the brain. Here, we describe an intravital imaging protocol based on gradient refractive index (GRIN) lenses in conjunction with confocal microscopy to inspect fluorescent cells at high resolution in deep-brain areas. The approach relies on implanted guide-tubes for the interchangeable use of GRIN lenses, thereby allowing imaging at different magnifications and increasing the effective field of view. For complete details on the use and execution of this profile, please refer to Butiaeva et al. (2021).

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 it
