Development of new methods to investigate the role of the avian hippocampus in memory formation in brown-headed cowbirds
Bibliographic record
Abstract
The hippocampus is known to participate in a variety of cognitive functions in humans, non-human primates, rodents, and birds. A great deal of previous research on the avian hippocampus has examined its role in spatial memory. A question regarding avian hippocampal function that remains unanswered is, what is its role in encoding, retention, and retrieval of spatial information? To answer this question I, 1) describe spatial and non-spatial versions of a touchscreen task and my attempts to determine if the spatial version of the task is hippocampus dependent, and 2) describe the development of an implantable cryoloop which can be used to reversibly deactivate the avian hippocampus. I found that cryoloops are a successful technique for use in birds, and results suggest the task will be appropriate for the research question. This work lays the groundwork for future studies in studying hippocampus’s function and the avian brain.

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.
