Diazepam improves aspects of social behaviour and neuron activation in <scp>NMDA</scp> receptor‐deficient mice
Bibliographic record
Abstract
NR1 knockdown (NR1KD) mice are genetically modified to express low levels of the NR1 subunit of N-methyl-D-aspartate (NMDA) receptors, and show deficits in affiliative social behaviour. In this study, we determined which brain regions were selectively activated in response to social stimulation and asked whether differences in neuronal activation could be observed in mice with reduced sociability. Furthermore, we aimed to determine whether brain activation patterns correlated with the amelioration of social deficits through pharmacological intervention. The cingulate cortex, lateral septal nuclei, hypothalamus, thalamus and amygdala showed an increase in c-Fos immunoreactivity that was selective for exposure to social stimuli. NR1KD mice displayed a reduction in social behaviour and a reduction in c-Fos immunoreactivity in the cingulate cortex and septal nuclei. Acute clozapine did not significantly alter sociability; however, diazepam treatment did increase sociability and neuronal activation in the lateral septal region. This study has identified the lateral septal region as a neural substrate of social behaviour and the GABA system as a potential therapeutic target for social dysfunction.

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.
