brain
BRAYN/breɪn/
The organ directing thought and nervous activity.
The scan shows the different regions of the patient's brain.
Etymology
Old English brægen already named the physical organ, so the selected sense preserves that older meaning. Its deeper origin is uncertain; no secure underlying image explains the name.
In context
