Neurochemistry and epileptology.

This paper gives an account of the global evolution of (neuro-)chemistry in epileptology with an emphasis on the role of the International League Against Epilepsy (ILAE), which declared in its constitution a mission "to make the epilepsy-problem the object of special study and to make practical use of the results of such study." As Epilepsia is the scientific journal of the ILAE, the review emphasizes papers published in the journal.
