Table 4

Extents of activation for IBM patients and healthy controls. Activation in neuroanatomically defined volumes of cortex during bulb squeezing with the right hand for individual patients with inclusion body myositis and for healthy controls are shown. Values for the patients are listed in numerical order (see table 1) from the top down for the right hand.
