Modelling affective pain in mice: Effects of inflammatory hypersensitivity on place escape/avoidance behaviour, anxiety and hedonic state.
The place escape/avoidance paradigm (PEAP) has been used to assess the affective component of pain in rats. Using the Complete Freund's Adjuvant (CFA) model of inflammatory pain, the current study aimed at developing a mouse version of PEAP and investigating the relation between PEAP and other behavioural responses, namely anxiety-like behaviour, locomotor activity, and hedonic state. ⋯ The PEAP results suggest that this paradigm might be successfully applied in mice to study affective pain. CFA treatment was associated with increased anxiety-like behaviour and anhedonia; however, this appeared unrelated to the PEAP responses.
