John Hughlings Jackson

John Hughlings Jackson (1835-1911) was a British neurologist known for his pioneering work in understanding the brain and its functions. He contributed significantly to our knowledge of epilepsy, proposing that seizures arise from disruptions in the brain's electrical activity. Jackson emphasized the idea of “hierarchical organization” in the brain, suggesting that higher brain functions depend on simpler, more basic processes. His observations, particularly regarding how certain brain regions control different body parts, laid the foundation for modern neurology and helped improve treatment approaches for neurological disorders. His work remains influential in both neurology and psychology.
