Promoting Education and Attainment of the Highest Level of Knowledge and Understanding of Clinical Neurophysiology

The International Federation of Clinical Neurophysiology (IFCN) has member societies in 62 countries. The IFCN mission is to promote best practice in clinical neurophysiology through education and research throughout the world. And our vision is to improve healthcare worldwide by understanding the nervous system and optimizing the diagnosis and treatment of its disorders through clinical neurophysiology.

In Memoriam Fernando Henrique Lopes da Silva

Fernando Henrique Lopes da Silva (Lisbon, January 24, 1935) has passed away on May 7, 2019. 

He received his Medical Degree from the University of Lisbon in 1959 and the PhD in Physiology from the University of Utrecht in 1970. He was appointed full professor of Physiology at Amsterdam University and scientific director of the Dutch Institute of Epilepsy. After this academic service, he was appointed Emeritus Professor in Amsterdam and invited professor at Lisbon University.

He leaves to all of us an invaluable scientific legacy, hard to summarize in a few words. He published hundreds of scientific papers investigating the role of brain oscillatory mechanisms using advanced EEG and MEG techniques. These studies have unveiled biophysical and neurophysiological oscillatory models of the interactions between cerebral neural systems underpinning vigilance, sleep, and cognitive-motor functions in physiological and pathological conditions (with a focus on Epilepsy). One of his last major contributions was to play the role of Editor, together with Don Schomer, in the production of the seventh edition of the master EEG handbook entiled “Niedermeyer’s Electroencephalography: Basic Principles, Clinical Applications, and Related Fields (2018).”

His scientific work has tremendously contributed to the development of Neurophysiology, Clinical Neurophysiology, and EEG theory. For this work, he was awarded a distinguished member of Academy of Sciences of The Netherlands and received several honorary distinctions in the fields of Clinical Neurophysiology and Neurosciences.
He also leaves to all of us a permanent reminder of academic and social responsibility, declined in his professional acts with a unique gentleman style. He defeated the time and made our time better. In his mourning announcement card, one can read the Portuguese verse “as árvores morrem de pé!” (“trees die on their feet”). An evergreen tree will ever stand in front of us.


The Board of Directors of the Federation hereby gives notice that the Annual General Meeting of the Federation will be held at Venue West Conference Services Ltd., Suite 301 – 1040 Hamilton Street, Vancouver, British Columbia, on the 26TH day of February, 2018, at 10 a.m. for the following purposes:

1. To receive the report of the directors to the members;
2. To receive the financial statements of the Federation for the period ended December 31, 2018;
3. To appoint an auditor for the Federation for the current fiscal year;
4. To confirm and ratify the election of Directors to ExCo; and
5. To transact such other business as may properly come before the meeting.

The new Extended International 10-20 System of the IFCN

The standard International 10–20 System (19 electrodes) does not include electrodes in the inferior chain (at the level of the preauricular point). Thus the

inferior-basal and anterior part of the temporal lobe, which preferentially picks up activity originating or propagating from the mesial temporal structures, is not sampled. Given that several frequent diseases (e.g., temporal lobe epilepsy due to hippocampal sclerosis, autoimmune epilepsy, Alzheimer’s disease) are characterized mainly by mesial temporal pathology, this region needs to be targeted through additional scalp electrodes in standard recordings.

The IFCN has endorsed a new Guideline (Seeck et al. 2017, The standardized EEG electrode array of the IFCN. Clin Neurophysiol 128:2070-2077) that addresses this problem. The standard International 10-20 System is extended by addition of the T9/T10 (10% inferior to T7/T8), F9/F10 (20% anterior to T9/10, or 10% inferior to F7/F8) and P9/P10 (10% inferior to P7/P8 or 20% posterior to T9/T10) electrodes, which results in a total of 25 electrodes (Figure).

The IFCN strongly recommends to use these 25 electrodes as a minimum for all standard EEG recordings.

Clinical Neurophysiology Practice is now listed on PubMed

Application  for our new open-access journal, Clinical Neurophysiology Practice for listing by PubMed Central was successful.
Now that we will be listed on PubMed Central, future papers will be indexed and available for the foreseeable future. However in addition those papers published prior to acceptance will be indexed back to issue 1, page 1.This is expected to occur in August or September, once a few administrative and technical issues about uploading to PMC have been addressed.

Potential authors are encouraged to think of this journal for submissions that are practice-orientated – technique updates, repetition and validation studies, normative data, illustrative case reports, see published articles for all issues back to 2016, details of the journal, and our guide for authors.
