Calcium signaling in Schwann cells at synaptic and extra‐synaptic sites: Active glial modulation of neuronal activity
Bibliographic record
Abstract
Glial cells are widely dispersed in the central nervous system (CNS) as well as in the peripheral nervous system (PNS). In the PNS, perisynaptic Schwann cells (PSCs) are the glial cells associated with the pre- and postsynaptic elements of the neuromuscular junction (NMJ). They, as other glial cells of the CNS, respond to high-frequency motor nerve stimulation with an increase in intracellular Ca(2+). In addition to detecting and responding to neurotransmission, PSCs are involved in short-term plasticity events where they depress neurotransmission through G-protein-dependent mechanisms and potentiate synaptic activity via Ca(2+)-dependent mechanisms. In this review, we will discuss evidence that outlines the role of PSCs in short- and long-term modulation of synaptic activity. We will also emphasize present functional similarities and differences in PSC activation at different NMJs. The importance of glial-neural interactions along myelinating axons will also be discussed.

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.
