Abstract
Previous studies have shown that prefrontal cortex (PFC) neurons carry task-related activity; however, it is largely unknown how this selectivity is implemented in PFC microcircuitry. Here, we exploited known differences in extracellular action potential waveforms, and antidromic identification, to classify PFC neurons as putative pyramidal or interneurons, and investigate their relative contributions to task-selectivity. We recorded the activity of prefrontal neurons while monkeys performed a blocked pro/antisaccade task in which they were required to look either toward or away from a peripheral visual stimulus. We found systematic differences in activity between neuron classes. Putative pyramidal neurons had higher stimulus-related activity on antisaccade trials, whereas putative interneurons exhibited greater activity for prosaccades. These findings suggest that task-selectivity in the PFC may be shaped by interactions between these neuronal classes. They are also consistent with the robust deficits in antisaccade performance frequently observed in disease states associated with PFC dysfunction.

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 it
