NGFI-A IMMUNOREACTIVITY IN THE PRIMATE RETINA: IMPLICATIONS FOR GENETIC REGULATION OF PLASTICITY
Bibliographic record
Abstract
In rodents, enriched environments drive the expression of the immediate early gene NGFI-A, a regulator of the plasticity marker Synapsin I. Both proteins have been implicated as mediators of plasticity in the rat mammalian retina. In the present work immunocytochemistry directed against these proteins was used to explore their basal activity in the retina of a more visual species, the New World monkey Cebus apella. In contrast to rat, monkey retina displayed high basal expression of both NGFI-A and Synapsin I. The greatest number of NGFI-A -expressing cells was observed within the inner nuclear layer, although NGFI-A positive nuclei were also found in the ganglion cell layer. High levels of Synapsin I were found in the inner plexiform layer and outer plexiform layer. Our findings are consistent with the postulate that the retinas of highly visual animals may experience ongoing reorganization as part of normal visual processing, and that NGFI-A and Synapsin I may be well positioned to regulate some of these changes.

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.
