                                                        Since the NC was evaluated as a start-up institute in

                                                      Scientific Council of the University of Helsinki decided to
                                                      use this evaluation as the basis of its recommendations
                                                      to the University Senate in 2006. The Scientific Council
                                                      unanimously recommended continuation of the NC,
                                                      and the University Senate concluded in June 2006 to
                                                      further extend the NC for the five-year period 2007-

                     In addition to graduate-level teaching, the NC
                cooperates with the Finnish Graduate School for
                Neuroscience (FGSN), the Helsinki Graduate School of
                Biotechnology and Molecular Biology (GSBM), and the
                Helsinki Biomedical Graduate School (HBGS) to arrange
                special courses for PhD training.
                     Furthermore, via its representative in NENS (Network
                of European Neuroscience Schools), the NC participates
                in creating standards for European Master’s and
                Doctorate degrees in neuroscience.

                teaching activities with the University of Kuopio, the
                Helsinki University of Technology, and other
                departments within the University of Helsinki. In human
                molecular genetics, the NC collaborates closely with
                Folkhälsan and the National Public Health Institute.
                     A commercialization program (NeuProtec) was
                launched in 2005 in collaboration with the Institute of
                Biotechnology and the Finnish Funding Agency for
                Technology and Innovation (TEKES). The aim of this
                program is to find novel tools for brain protection. A
                further aim is to create spin-off industrial activity based
                on neuroscience research during the next few years.
                     The NC was actively engaged in arranging the Brain
                Awareness Week in 2006, an activity now planned to
                take place yearly to enhance public understanding of
                neuroscience research. In this context, the initiative of
                the Brain Foundation of Finland (Suomen Aivosäätiö)
                was launched in 2006.

                Towards the Second Five-Year Period
                After my five-year term as Director, I feel that the NC can
                now be regarded as an established institution. I expect
                that during the second five-year period, which is now
                starting, the NC will have an even stronger impact in
                research. Teaching that corresponds to a Master´s

Program in Neuroscience has now been implemented
for three years and will be formally established in 2008.
Together with PhD training courses, the Master´s
courses will be an important activity of the NC.
     Functions of the NC would not have been possible
without the competitive funding that currently
comprises about 60 % of the budget of the NC. In
particular, the Sigrid Jusélius Professorhip in
Neuroscience has been invaluable to the NC. A large
proportion of our budget has been covered by
numerous grants from the Sigrid Jusélius Foundation,
the Academy of Finland, and the Finnish Funding
Agency for Technology and Innovation (TEKES).
     In conclusion, I would like to thank everyone at the
NC, our collaborators, and the members of the Boards
for making the Center an inspiring place to work. I am
very much looking forward to an even brighter five-year
term.

Research Groups

T   he mission of the Neuroscience Center is to carry out excellent and multidisciplinary research on the development,
    normal functions and disorders of the nervous system. Research and teaching in the NC focus on the following four
areas: molecular and cellular neuroscience, developmental neuroscience, cognitive and systems neuroscience, and basic
research of the nervous system diseases. The research groups work in at least one of the research areas of the NC. In
2006, there were seven research groups working in the NC.

T   he Neuroscience Seminar Series has been organized regularly since 2003 and has proven to be an important
    instrument of scientific exchange as well as student education. In 2006, over 20 seminars were held by international
and Finnish research scientists ranging from young independent researchers to celebrated Nobel laureate level. Speakers
are usually invited by the Neuroscience Center group leaders, and seminars cover a broad range of topics from
Neuroscience to Cell Biology. The audience of 30 to 50 people consists of graduate students, postdoctoral fellows and
senior faculty members. Guest speaker presentations are always followed by questions from the audience and vivid
discussions. For PhD students, regular attendance and active participation in the Neuroscience Seminars is counted as
points towards their study plan. In addition to the main presentation, each invited speaker is encouraged to spend time
with a number of group leaders individually, engaging in a more in-depth discussion of recent findings and mutually
interesting scientific questions.

                                                     project which has retained its usefulness. Production of
                                                     knockout mice using blastocyst injection was
                                                     established soon after classical transgenics. Morula
                                                     aggregation is currently mainly used for the production
                                                     of knockout mice.
                                                          The Transgenic Unit produces overexpressing and
                                                     knockout mice for the projects of several research
                                                     groups on the Viikki and Meilahti campuses, both
                                                     within and outside the Neuroscience Center. Altogether,
                                                     about 200 different mouse lines were produced during
                                                     1996-2005. Since Biomedicum on the Meilahti campus

                                                     are the main users of mouse transgenics.
                                                          An increasingly evident problem in mouse
                                                     transgenics is contamination of imported mouse lines,
                                                     which prevents housing in the animal facility and
                                                     increases the risk of facility contamination. Therefore,
                                                     purification of mouse lines using embryo transfer has
                                                     been established. In addition, freezing of mouse
                                                     embryos is carried out to ensure back-ups and for long-
                                                     term storage of mouse lines that are no longer under
                                                     active investigation.
                                                          By far, the major limiting factor in mouse transgenics
                                                     is inadequate capacity in the animal facility, resulting in
                                                     the expertise of the Unit not being fully exploited. The

                                                     particular, requires large mouse colonies, and therefore,
                                                     sufficient housing facilities. State-of-the art testing in
                                                     behavioural studies also requires large numbers of
                                                     animals. Building a new animal facility is necessary
                                                     before increasing the number of studies using
                                                     transgenic mice.

                 T    he Commercialization program is co-funded by the
                      Finnish Funding Agency for Technology and
                 Innovation (TEKES) and the Neuroscience Center.
                 Commercialization is carried out by collaboration with
                 research groups. Various research projects are evaluated
                 on their commercial potential and industrial
                 applicability. The current project entity (NeuProtec)
                 includes four different projects: three of them aim to
                 show a proof of concept on efficacy for therapeutic use
                 in neurodegenerative diseases, and the aim of the
                 fourth project is to provide proof of concept and
                 scalability of a technology platform for screening small
                 synthetic molecules for the treatment of neuro-
                 degenerative diseases.
                      NeuProtec is a novel way of including commercial
                 aspects in research projects. NeuProtec is funded by
                 TEKES. The parties in this current research collaboration
                 include professors Eero Castrén and Heikki Rauvala
                 from the Neuroscience Center and professor Mart
                 Saarma from the Institute of Biotechnology and their
                 research groups. The target of this joint activity with
                 science and commercialization is to increase the value
                 and applicability of research results for industrial
                 utilisation.
                      The four projects are based on long-term research
                 performed in the groups. The commercial management
                 and collaboration includes management of IPR
                 (patents), contractual matters and fund raising. Thus it
                 provides a frame for fulfilling basic commercial criteria.
                 This collaboration is expected to enhance
                 commercialization of the research results by providing
                 industrial criteria to applied science, to a level where it is
                 possible with academic resources.
                      This is a pioneer program for applying the new, third
                 legal assignment for universities.
