Eloquent area located tumor #awakesurgery, Iceland

by Iceland "Neurophysiology Plus" Informal Grup

Reykjavík, December 2016

On 1st of December 2016, a patient with left frontal lobe space-occupying lesion was operated with awake surgery in Iceland.

A team coordinated by Ingvar Ólafsson performed preoperative neuropshychological tests and intraoperative direct brain cortical stimulation in awake patient to localize motor speech area with the aim to avoid possible neurological injuries during the procedure. The patient collaborated very well and the removal of the tumor was performed always with the patient in awakefullness performing speech mapping and several specific cognitive tests (here).

Isocinetic exercise versus isometric exercise and Cutaneous Silent Period

by Ovidiu C. Banea

Reykjavik, 18 July 2016

During summer 2016, members from Neurophysiology Unit Landspitali University Hospital, Fossvogur, Iceland (Neurology Department) are conducting an experiment using novel technique of Cutaneous Silent Period (CuSP) at baseline conditions and after two type of interventions (isocinetic and isometric exercise) in upper limb nerve-muscle "reflex" as following: median nerve - abductor pollicis brevis and ulnaris nerve - first interosseous. The aim of this work is to analyse the contribution of sensory inputs to the cutaneous silent period and if there are changes after isometric exercise suggesting involvement of other afferent fibers (beside of small mielinated A-delta) to the CuSP onset, like those of muscle spindles.
