Abstract

fetched live from OpenAlex

Sexual differentiation is a well characterized phenomena of the mammalian central nervous system. There are many structural and functional sex differences characterized throughout the brain and have been well studied. Unfortunately, less well understood is the sexually dimorphic prevalence of psychiatric, neurological, and mood and anxiety disorders in the human population. Many of which have developmental etiologies coinciding with organization of the neocortex. The developmental trajectory of the neocortex has a distinct and well understood temporal and mechanistic patterns. Astroglial cells are fundamental in neocortical development by facilitating radial neuron migration, synaptic maturation and pruning in addition to their neurogenic potential. Sexual dimorphism of astroglial and cells in the neocortex has not been studied. This study examines the phenotypic changes of cortical astroglial cells in postnatal development of both sexes. Although our study yields mixed results, the neurogenic potential of cortical astroglia is sexually dimorphic in the perinatal period.

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.
