A focal seizure characterized by elementary auditory phenomena including buzzing, ringing, drumming or single tones. More complex auditory hallucinations such as voices are considered a focal cognitive seizure. Focal sensory auditory seizures involve auditory cortex in the lateral superior temporal lobe.

Focal sensory visual seizure

A focal seizure characterized by elementary visual hallucinations such as flashing or flickering lights/colours, or other shapes, simple patterns, scotomata, or amaurosis. More complex visual hallucinations such as seeing formed images are considered a focal cognitive seizure. Focal sensory visual seizures arise in the occipital lobe.

Focal somatosensory seizure

A focal seizure characterized by sensory phenomena including tingling, numbness, electric-shock like sensation, pain, sense of movement, or desire to move. These seizures involve the sensorimotor cortex.
