In vitro Neurophysiology of Identified Rat Hypothalamic ‘Neuroendocrine’ Neurons
Bibliographic record
Abstract
Stable synaptic and antidromic electrophysiological recordings were obtained for 10-15 h from identified neurohypophyseal and tuberoinfundibular neurons using an acute explant of rat hypothalamus maintained in vitro through perfusion of the carotid artery with oxygenated artificial media. Synaptic potentials from preoptic and median eminence stimulation were blocked during perfusion with 12 m M Mg++-containing solutions. Antidromic and spontaneous action potentials recorded in neurohypophyseal neurons were followed by a transient after-hyperpolarization of 3-10 mV, due primarily to a brief increase in potassium conductance. Evidence favoring the existence of a synaptic recurrent inhibitory pathway was present in records obtained from tuberoinfundibular neurons, but not from neurohypophyseal cells.

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.
