A Review of the Association Between Environmental Harshness, Neurogenesis and Caching Behaviour
Bibliographic record
Abstract
Memory is one of the most crucial cognitive functions in many organisms. It is highly implicated in everyday functioning and is an essential component for survival. Past research has revealed that spatial memory facilitates bird caching behaviours such as remembering the exact locations of their hidden food. However, there are many factors that alter the demands on memory and consequently impact the function of caching. Specifically, neurogenesis, the process of forming new neurons, has been shown to affect this behaviour. Likewise, environmental variables and selective pressures (i.e., severity of the environment) can also influence caching in birds. In this review, we present evidence for a link between environmental harshness, hippocampal neurogenesis, and caching behaviour in chickadees, with specific focus on work by Chancellor et al. [6]. Neurogenesis in chickadees may be a mechanism subject to selective pressures, in which chickadees from harsher environments have increased neurogenesis rates and consequently enhanced caching ability. However, there remain gaps in the understanding of how exactly hippocampal neurogenesis, environmental harshness, and caching behaviour interact, and future studies are needed to further explore this interaction and its implications.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
