[Professor Hans Otto Lüders].

Area of Science:

• Clinical Neurology
• Epilepsy
• Clinical Neurophysiology

Background:

• Pioneered chronic subdural electrode implantation for epilepsy surgery evaluation.
• Introduced stereotactic depth electrodes for deep-seated epileptic foci.
• Imported European techniques for advanced presurgical evaluation.

Discussion:

• Discovered new eloquent cortical areas, including the basal temporal language area and "negative motor areas" linked to praxis.
• Identified the dominant posterior fusiform gyrus's role in reading (alexia without agraphia).
• Developed a seizure classification based on semiological characteristics, defining new seizure types.

Key Insights:

• Established six zones characterizing epilepsies: epileptogenic, irritative, seizure onset, lesion, symptomatogenic, and functional deficit.
• Described the ictal DC shift for localizing seizure onset zones in focal seizures.
• Advanced understanding of epilepsy pathophysiology and localization.

Outlook:

• Continued refinement of presurgical evaluation techniques.
• Further exploration of newly identified eloquent brain regions.
• Integration of semiological classification into clinical practice.
