Purpose

Measures electrical activity in the brain to diagnose coma depth

Significance

Proves the Doctor's coma defies human norms, reveals alien physiology, and heightens UNIT's urgency by showing medical helplessness

Brigadier confronts Doctor’s alien coma

The EEG machine is central to this event, serving as the primary diagnostic tool used by Henderson to explain the Doctor’s coma. Its flatline reading—indicating no brain activity—challenges the Brigadier’s understanding of the Doctor’s condition and underscores the limitations of human medicine in diagnosing alien physiology. Henderson uses the machine to illustrate the Doctor’s self-induced state, reinforcing the idea that his coma is not a result of physical trauma but something far more complex. The machine’s readings create a sense of unease, as they defy medical logic and highlight the Doctor’s otherworldly nature.

Before: Functioning normally, connected to the Doctor’s head and displaying typical EEG patterns for an unconscious human patient (though the Doctor is not human).

After: Still connected to the Doctor, now displaying a flatline with no electrical activity, confirming the depth of his coma. The machine remains a point of focus for the characters as they grapple with its implications.
