From: Automatic seizure detection using three-dimensional CNN based on multi-channel EEG
The single-channel EEG recordings illustrating typical brain states. The typical brain states of epilepsy patients include pre-ictal, ictal and inter-ictal three states. An hour segment before each seizure was defined as a pre-ictal state. Neurophysiology experts annotated ictal state. EEG data of the signal that were neither pre-ictal nor ictal defined as inter-ictal states. The figure represents the whole process of brain electrical signal seizure
