Getting my degrees at the University of Twente
as well as my work as a clinical physicist at the
Neurology department of Leiden
University Medical Centre (35 years since 1977)
and at the Sleep center of the Medical Centre
Haaglanden (22 years after I co-founded it in
1992) was an engineers dream. Together with brilliant
minds in electronics,
mathematics and physiology I created new practical stuff at
the boundary between those fields. Some of our creations still (2014) beat the competition: neuroloop
analysis of slow-wave and spindle networks (with implementations),
analysis, the European Data Format
monitoring at home with smart ambient
sensors, and finally the sleep-lab softwares Polyman
published some of all this and uploaded a
texts that are still important for EEG
and Sleep research. In particular the professional organizations that
advocate sleep medicine need to implement more of the present physio-mathematical
state-of-the-art of which these articles represent a portion.
I have now started a
completely new life and retired from work. Looking back
for more than 45 years, I am particularly grateful to
the following great people that I had the privilege to
work with most intensively. During my studies I grew
J K Buesink a
practical engineering attitude, with E Willem Grőneveld an intuition for good mathematical
theory, and with Fernando H Lopes da Silva the conviction that it was a good idea
to combine those in the field of neurophysiology. While
doing that in my two jobs, I worked most intensively with Henk A P Blom (neuro-feedback),
Jan M Franzen, Teunis van Beelen, Marco J Roessen and the late Ad J M W Janssen
(electronics and software), and most recently with my
successor Diego Álvarez Estévez (brain-sleep analysis).
Together we were brain engineers and we shared the fun
to create better and unprecedented sensors, electronics,
mathematics and software. Some medical doctors like Al W
de Weerd and the late Hilbert A C Kamphuisen saw our
potential and substantially facilitated our work. Great support also came from the
European Commission that funded quite a few
international play-fields where we shared our fun with
Alpo Värri, Thomas Penzel and Agostinho C da Rosa who
are still in the same field, and of course many many
you all. It was good.
