Reykjavik, 9th of August 2018
A team of young researchers leaded by biomedical engineer Dr Paolo Gargiulo, from Reykjavík University, Department of Biomedical Engineering performed successfully the first data acquiring for a healthy subject recording P300, P50 and dense array 256-channel EEG.
P300 was first used in Iceland by Sigurjón B. Stefánsson and Anna L. Möller since the nineties.
Scientific data was published in
1995 and
2001 and
2005.
In July 2017 P300 returned to Iceland in Clinical Neurophysiology Unit of Landspitali (
here).
P50 was acquired first time in patient with tinnitus on 20th of February 2018 in a paired-stimulus
or conditioning-testing paradigm, (S1, conditioning click; S2, testing click; 500 ms inter-click interval; 10,000 ms inter-pair interval). This was a trial of 30 paired stimulus with sensory gating with stimulus in the left and observed from Cz-A2 (right cortex) and with absent wave and response from the left Cz-A1 channel when stimulus was applied for the right ear.
Today the team formed by:
Viktor Díar Jónasson, Clinical Psychology master student at the Department of Psychology, Reykjavik University
Fabio Barrolo, PhD student at Reykjavik University Iceland / Aston University, Birmingham, UK, Biomedical Engineering
Valerio Gargiulo, Research assistant at the Icelandic Center for Neurophysiology, legal advisor and EEG technologist at Department of Biomedical Engineering, Reykjavík University
Eysteinn Ívarsson, Psychologist and technologist at Clinical Neurophysiology Unit, National University Hospital of Iceland
Ovidiu Banea, PhD student at Reykjavík University, Department of Biomedical Engineering and Clinical Neurophysiologist MD at National University Hospital of Iceland
performed both P300 and P50 acquisition with dense array 256 channel EEG system at the Icelandic Center for Neurophysiology, Department of Biomedical Engineering, Reykjavík University
