NMDA Receptor-dependent Long-term Depression in the Anterior Cingulate Cortex
Bibliographic record
Abstract
Neurons and synapses in the mammalian brain exhibit plastic changes, which occur not only during development and under physiological conditions, but also under pathological conditions. One major cellular hypothesis is that activity-dependent changes in synaptic strength may contribute to the formation of memory and the expression of persistent inflammatory pain. Recently, the anterior cingulate cortex (ACC) has been proposed to play an important role for learning, memory and chronic pain. Long-term potentiation (LTP) and long-term depression (LTD) are well-studied phenomena which may be related to learning and memory. NMDA receptors are the most important trigger for LTP and LTD of synaptic strength. Here, we review recent studies and present new experimental data on the roles of NMDA receptors during synaptic depression in the ACC. Furthermore, we consider the physiological and pathological significance of LTD in the ACC.

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.
