ATP potentiates neurotransmission in the rat trigeminal subnucleus caudalis
Bibliographic record
Abstract
Ionotropic purine receptors (P2X) have been implicated in nociceptive neurotransmission. In this study, we examine the actions of the P2X receptor agonist alpha,beta methylene adenosine 5'-triphosphate on excitatory neurotransmission in neurons in the deep and superficial laminae of the trigeminal spinal subnucleus caudalis (Vc), which receives nociceptive inputs from the craniofacial region. Alpha, beta methylene adenosine 5'-triphosphate caused an increase in spontaneous excitatory neurotransmission (miniature excitatory postsynaptic currents) in neurons in deep but not superficial laminae of Vc; this effect could be inhibited by the P2X receptor antagonist 2,3-O-2,4,6-trinitrophenyl-ATP. Conversely, the TRPV1 agonist capsaicin caused an increase in miniature excitatory postsynaptic currents in neurons in the superficial but not deep laminae. These data suggest that alpha,beta methylene adenosine 5'-triphosphate acts on presynaptic terminals to increase glutamatergic neurotransmission in deep Vc neurons.

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.
