Neuroanthropology of shamanic trance: a case study with a ritual specialist from Mexico.

In Mexico, shamans are recognized for the gift of entering a deep trance that allows them to know the origin of the diseases and conflicts that afflict people. They commonly treat patients through (cleansing) to extract negative elements sent by a witch or that were "collected" in places that harbor "evil winds." We present a case study of an 81-year-old Mexican shaman who noticed her gift in childhood.
