Abstract
The aim of this study is to investigate the effects of pregabalin on the behavior of rats under the influence of ketamine, an NMDA receptor antagonist that mimics the symptoms of schizophrenia. Rats were injected with saline or 25 mg/kg ketamine intraperitoneally. After that, behavior modifications were investigated by the evaluation of stereotypy and hyperlocomotion, after treating rats with pregabalin (at doses of 30 mg/kg or 100 mg/kg) or placebo (saline solution). The administration of pregabalin reduced ketamine-induced hyperlocomotion. However, neither doses of pregabalin had a significant effect on ketamine-induced stereotypy. This is the first study to investigate the effects of pregabalin using an animal model of psychosis. Furthermore, our results indicate that behavioral changes induced by ketamine in rats can be reversed with the use of pregabalin, suggesting its potential to treat psychotic symptoms. O presente estudo tem como objetivo investigar os efeitos da pregabalina sobre as alterações comportamentais em ratos induzidas pela cetamina, um antagonista do receptor glutamatérgico NMDA, utilizado em modelos animais de psicose. Ratos receberam injeção com solução salina ou cetamina, na dose de 25 mg/kg, com posterior avaliação das alterações comportamentais induzidas, através da avaliação da estereotipia e hiperlocomoção, depois destes ratos terem sido tratados com pregabalina (30 mg/kg ou 100 mg/kg) ou placebo. A administração de pregabalina reduziu a hiperlocomoção nos ratos sob o efeito da cetamina. No entanto, nenhuma das doses de pregabalina teve efeito significativo sobre a estereotipia induzida pela cetamina. Este é o primeiro estudo que investiga os efeitos da pregabalina em um modelo animal de psicose. Nossos resultados indicam que alterações comportamentais induzidas pela cetamina em ratos podem ser revertidas após uso da pregabalina, o que sugere um possível potencial desta no tratamento de sintomas psicóticos.

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
