Disconnected cerebral hemisphere in epilepsy patients shows sleep-like state during wakefulness (IMAGE)
Caption
This metaphorical illustration reimagines a hidden view of the brain of a patient with hemispherotomy. In the absence of subcortical activating inputs, the disconnected cortex defaults to a sleep-like state, marked by slow-wave EEG activity and evocatively represented here as night. By contrast, the intact hemisphere, still integrated with subcortical structures, sustains wakefulness and a bright inner world capable of environmental interaction, reflected in faster EEG rhythms. The image underscores the divergence of cortical states after hemispheric isolation.
