A Review of Glutamate Receptors I: Current Understanding of Their Biology
Bibliographic record
Abstract
Seventy years ago it was discovered that glutamate is abundant in the brain and that it plays a central role in brain metabolism. However, it took the scientific community a long time to realize that glutamate also acts as a neurotransmitter. Glutamate is an amino acid and brain tissue contains as much as 5 - 15 mM glutamate per kg depending on the region, which is more than of any other amino acid. The main motivation for the ongoing research on glutamate is due to the role of glutamate in the signal transduction in the nervous systems of apparently all complex living organisms, including man. Glutamate is considered to be the major mediator of excitatory signals in the mammalian central nervous system and is involved in most aspects of normal brain function including cognition, memory and learning. In this review, the basic biology of the excitatory amino acids glutamate, glutamate receptors, GABA, and glycine will first be explored. In the second part of this review, the known pathophysiology and pathology will be described.

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.
