dc.description.abstractotrodiomaInjury to the insular cortex in humans produces a lack of appropriate response to pain. Also, there is controversial evidence on the lateralization of pain modulation. The aim of this study was to test the effect of insular cortex lesions in three models of pain in the rat. An ipsilateral, contralateral or bilateral radiofrequency lesion of the rostral agranular insular cortex (RAIC) was performed 48h prior to acute, inflammatory or neuropathic pain models in all the experimental groups. Acute pain was tested with paw withdrawal latency (PWL) after thermal stimulation. Inflammation was induced with carrageenan injected in the paw and PWL was tested 1h and 24h afterwards. Neuropathic pain was tested after ligature of the sciatic nerve by measuring mechanical nociceptive response after stimulation with the von Frey filaments. Another model of neuropathy consisted of thermo stimulation followed by right sciatic neurectomy prior to the recording of autotomy behaviour. Acute pain was not modified by the RAIC lesion. All the RAIC lesion groups showed diminished pain-related behaviours in inflammatory (increased PWL) and neuropathic models (diminished mechanical nociceptive response and autotomy score). The lesion of the RAIC produces a significant decrease in pain-related behaviours, regardless of the side of the lesion. This is a clear evidence that the RAIC plays an important role in the modulation of both inflammatory and neuropathic - but not acute - pain.es_ES
