The insula, particularly its posterior portion, is often regarded as a primary cortex for pain. However, this interpretation is largely based on reverse inference, and a specific involvement of the insula in pain has never been demonstrated. Taking advantage of the high spatiotemporal resolution of direct intracerebral recordings, we investigated whether the human insula exhibits local field po...

An interesting and valuable discussion has arisen from our recent article (Segerdahl, Mezue et al., 2015) and we are pleased here to have the opportunity to expand on the various points we made. Equally important, we wish to correct several important misunderstandings that were made by Davis and colleagues that possibly contributed to their concerns about power when assessing our paper (e.g. ac...

The case details and outcome after surgical decompression of 46 dogs with thoracolumbar intervertebral disc disease with loss of deep pain perception prior to surgery were reviewed. Nineteen dogs (41.3%) recovered with a median follow-up period of 12.5 months. Recovery was defined as an ambulatory paraparesis, or better, with urinary and fecal continence. There was a better outcome in dogs with...

OBJECTIVE As pain during childbirth is very intense, several educational programs exist to help women prepare for the event. This study evaluates the efficacy of a specific pain management program, the Bonapace Method (BM), to reduce the perception of pain during childbirth. The BM involves the father, or a significant partner, in the use of several pain control techniques based on three neurop...

BACKGROUND There is ample research to support the existence of bias in the perception of others' pain. Both studies involving health-care professionals and student surrogate samples have found that, firstly, pain is under-perceived when using nonverbal cues to gauge another's suffering and, secondly, that personal characteristics of both the viewer and the target (such as gender) can bias pain ...

Introduction: The current investigations on Health Equity, primarily point to the harmful health consequences of being in a stressful social hierarchy. The repetitive nature of social conflicts seems to favor the induction of hyperalgesia or hypoalgesia both in rodents and humans, and it can also affect the immune system. In this study, the effects of changes in social status on pain percept...
