Neonatal experience with unpaired odour-shock enhances colorectal sensitivity in adult rats. In adult rats previously exposed to neonatal unpredictable pain, the level of colorectal sensitivity to luminal distension was assessed. Colorectal distension at pressures of 20, 40 and 60 mmHg for 10 min in the unpaired odour-shock group exhibited a greater visceromotor behavioural response (measured as the number of abdominal contractions per 10 min distension period), when compared to the odour-only and paired odour-shock treatment groups (*P < 0.05; **P < 0.01 from unpaired treatment group).
