Effects of Transcranial Random Noise Stimulation on Perception of Dynamic Audio-Visual Emotional Facial Stimuli
Bibliographic record
Abstract
The human ability to perceive emotions accurately and quickly strengthens social communication and interactions. The human mirror neuron system (hMNS) is a prominent brain network that has been implicated in action perception and more recently, emotion perception. The current study applied transcranial random noise stimulation (tRNS) to the inferior frontal cortex (IFC; a major node of the hMNS) to assess the neural and behavioural effects. The study also uses dynamic audio-visual portrayals of emotion to increase ecological validity. Compared to the sham group, active tRNS led to greater mu-event-related desynchronization (mu-ERD) to emotional stimuli, marginally faster response time, and significantly decreased accuracy. These results suggest that active tRNS over the IFC leads to a mode of embodied responding to dynamic emotional stimuli that may involve less cognitive deliberation.

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.
