Brain tumors, and more particularly diffuse gliomas, are highly epileptogenic. Epidemiologic and experimental studies point that tumor growth and epileptogenesis are associated, sometimes in a contradictory manner: tumors with a specific growth pattern are more epileptogenic; epilepsy occurrence is associated with an improved oncologic outcome increased neuronal activity promotes tumoral growth; common mechanisms mainly involving glutamatergic excitatory signalling and GABAergic inhibitory signalling contribute to both epileptic and oncologic process. This study aims at better understanding two major protagonists involved in seizures initiation: extracellular K+ and neuronal Cl- concentrations dynamics that respectively underlie local excit...
