Study: Surgeon enthusiasm linked to high spinal procedure rates

Surgeons in some areas are more likely to recommend surgery for low back problems—and those differences in "surgeon enthusiasm" are a major factor driving regional variations in spinal surgery rates, suggests a study in the March 14 issue of Spine. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

New study reveals brain networks are involved in 'cross-modal' person recognition

Human social interactions are shaped by our ability to recognise people. Faces and voices are known to be some of the key features that enable us to identify individual people, and they are rich in information such as gender, age, and body size, that lead to a unique identity for a person.
