The Irwin testa is a standard and consolidated neurobehavioural observation battery for assessing CNS adverse effects inrodents, attempts to adapt this test to non-human primates over the conduct of pre-clinical risk assessment are rare. However, itmay be necessary to assess neurobehavioral outcome of either test articles exposure or experimental procedures in these species.For this reason a modified Irwin test in the cynomolgus monkey was established in these laboratories.

To also evaluate the absence of technique-related neurobehavioural changesneurological examinations (sensorimotor expressions, cerebral nerve tests and spinal nerve tests) were performed pre-dose andonce weekly over the study conduct. Determinations of neurobehavioural parameters (vocalisation, aggression, convulsion,posture, reaction, alertness, coordination, visual stimuli, muscle tone, stereotypy, locomotor activity, grip strength, grooming, andtremors) were conducted pre-dose, in weeks 1 and 4. In summary, the data showed the absence of neurobehavioural changes whencomparing pre-surgery and post-surgery observations. The modified Irwin test proved practical and provided reproducible data.
