Sex, age, body fat, and postprandial glucose, insulin, and free-fatty acid response.

Coordinates are from the brain atlas of Talairach and Tournoux (1988), such that x is the distance in millimetres to the right (+) or left (−) of midline, y is the distance in millimetres anterior (+) or posterior (−) to the anterior commissure, and z is the distance in millimetres superior (+) or inferior (−) to a horizontal plane through the anterior and posterior commissures.
