EP and brainstem reflexes in patients with large temporal brain tumours

To find possible functional irritation of reflex and sensory neural pathways of the brain and of the brainstem caused by lateralised supratentorial mass shift, 55 patients with large temporal brain tumours were electrophysiological investigated. In this patients the electrical (BR) and mechanical (GR) elicited blinking reflex, the jaw-reflex (MR) were derived as well, as the acoustic (BAEP) the somato-sensory (MSSEP) and the flash elicited visual (f-VEP) evoked potential. The infratentorial generated BR, GR and BAEP showed very frequently (>3/4 of the cases) slight pathological changes (pontine and ponto-bulbar)…
