Activation during swallowing of primary motor cortex (BA4) and premotor cortex (BA6/8) in the right/left cerebral infarction group and the control group.

Patients with right cerebral infarctions and swallowing dysfunction exhibited smaller activation volume in right BA4 and right BA6/8 and larger activation volume in left BA6/8 compared with controls. Activation volume in left BA4 did not differ between these patients and controls. Similarly, patients with left cerebral infarction and swallowing dysfunction exhibited smaller activation volume in left BA4 and BA6/8 and larger activation volume in right BA4 and BA6/8. R: Right.
