HELPING NEURONS TO REMEMBER: SYNAPTIC PLASTICITY, MENTAL RETARDATION AND A STIMULATING ENVIRONMENT
Speaker: PROFESSOR DR HUIBERT MANSVELDER (VU, CNCR)
Huib Mansvelder (1968) is head of the Research Group "Functional Imaging of Neuronal Networks" at the Center for Neurogenomics and Cognitive Research (CNCR, VU University, Amsterdam). His research focusses on "Plasticity and dynamics of neuronal networks involved in cognition". He received a VIDI grant from NWO in 2006 (Elucidating the cognition enhancing effects of nicotine) and is a member of "De Jonge Akademie" (Royal Dutch Academy of Sciences).
Learning and memory are fundamental cognitive functions of our brain.
When information is acquired and stored the contact points or synapses between neurons change. In patients suffering from syndromes associated with low IQ, such as Fragile X syndrome, learning and memory abilities are reduced. Neurons and synapses in the brains of these patients show an altered appearance and functionality. In a mouse model of Fragile X, we find that the ability of synapses to change is strongly reduced. The synapses can change but it takes more effort. Using two-photon laser-scanning microscopy, which enables visualisation of synapses in living brain tissues and studying their functionality, we find that calcium signalling is unreliable. Mechanisms for synaptic plasticity are in place, but require stronger neuronal activity to be triggered. I will discuss the mechanisms underlying deficits in synaptic plasticity and calcium signalling in mental retardation, and show how synaptic plasticity can be restored by stimulating environments.

Beste Biologiemedewerker,
De feestmaand ligt alweer een week achter ons... of toch niet?
niet als het aan het LBC en IBL ligt!
Graag nodigen wij U uit voor het 'Old meets New' nieuwjaarsfeest dat door hen samen wordt georganiseerd. Iederren van de opleiding biologie is van harte welkom, zowel studenten als medewerkers.
Wanneer: Donderdag 17 januari 2008
Waar: Cafe De Tregter
Aanvang: 20:00 uur
kosten: GEEN!
En waarom zou U daar even komen kijken?
Misschien omdat biologie (oud)studenten en Wim van Leeuwen live bandoptredens zullen verzorgen.....
Omdat studenten en wellicht Tom de Jong hun kunsten als DJ gaan vertonen....
en wie weet omdat het heel gezellig is een drankje te doen en een dansje te wagen met collega's...
Vanaf 22:00 beginnen de bands te spelen.
Freaks of Nature en radio Moscow
Wij hopen U te kunnen verwelkomen op ons feest!
Het IBL en de LBC

Theme: Rewilding the Netherlands, Lions in the Veluwe?
This symposium will highlight the importance of insights from behavioural biology to applications in conservation.

To attend the symposium, please send an E-mail to: Rewildingsymposium@biology.leidenuniv.nl, before 17 December.
The symposium takes place at the Grote Collegezaal,
Kaiserstraat 63, 2311GP Leiden.

Conference theme: Rewilding the Netherlands
This symposium will address the idea of “Re-wilding in America”, as featured in several high-impact scientific journals (Nature, Science) over the last few years.
The idea of re-installing top-predators and large herbivores, such as African lions and elephants on the great plains in the USA has been controversial, but we think the ecological and behavioural rationale behind it certainly warrants serious attention. For most of us it might sound ridiculous, but a number of famous scientists are pleading for this idea. This conference will address the arguments both for- and against rewilding.
The Rewilding idea is a hot and current topic in which many discussion is taking place between scientists that are for and against the implementation of large herbivores and carnivores.
In the Netherlands there are similar ideas for the reintroduction of top predators such as the wolf in the Veluwe.
We envision an interesting discussion, especially in the context of
1) the high number of wild boars in the Veluwe in the absence of large carnivores, and of
2) the reintroduction of European bisons in the Dutch dunes, which has already taken place.
We hope that during this symposium we are able to provide a clear perspective on the theoretical considerations and practical implications of the rewilding concept.
Thus the Rewilding concept is current and controversial and thus is our focus for the Behaviour & Conservation symposium 2007.

NEURON-CHIP INTERFACING: A MULTI-DISCIPLINARY APPROACH TO UNDERSTANDING BRAIN FUNCTION AND REPAIR
Speaker: PROFESSOR DR NAWEED SYED (CALGARY)
Naweed Syed, neuroscientist (Canada, 1957; BSc, MSc, University of Karachi;PhD, 1988, University of Leeds) is head of the Departments of Cell Biology & Anatomy and Physiology & Biophysics of the Faculty of Medicine, University of Calgary. He conducts studies on brain development and regeneration. His research looks at how brain cells recognize and connect with each other, how they establish the intricate network of synapses that forms the basis of brain function, and how the brain repairs itself during regeneration.
All nervous system functions, ranging from simple reflexes to complex motor patterns and learning and memory are controlled by large networks of brain cells. Thus, if one wants to understand how brain controls various functions, it is imperative that one acquires the ability to simultaneously, and non-invasively monitor the activities of large neuronal ensembles - a possibility that does not current exist in the field of neuroscience. Moreover, because natural replacement of injured nervous tissue seldom, if ever occurs in the intact brain, it is essential that we develop novel technologies whereby brain tissue can be interfaced directly with the electronics. Such an approach must ensure a two-way link between the electronics and the neurons. By interfacing individual neurons with silicon chips, we have developed such a bionic hybrid which enables us to stimulate and record neuronal activity from synaptically connected brain cells. Evidence will be presented to demonstrate that such a brain-chip interfacing approach holds tremendous potntial for further brain controlled prosthetics and regeneration devices.

Het is nagenoeg zeker dat de mensheid het klimaat de komende tijd zal blijven beïnvloeden. Wat is de wetenschappelijke onderbouwing van deze stelling? In hoeverre kunnen we een complex systeem, zoals het klimaatsysteem, begrijpen en voorspellen? Hoe gaat men om met onzekerheid, in de klimaatwetenschap, bij besluitvorming en in het maatschappelijk debat?

Wat weten we zeker over de op handen zijnde opwarming van de aarde, het smelten van de ijskappen en de stijging van de waterspiegel? Hoe belangrijk is de hedendaagse, door Al Gore recentelijk aangezwengelde, strijd tegen het broeikaseffect? Is de door de mens veroorzaakte bijdrage aan de klimaatverandering desastreus? Welke gevolgen hebben de te verwachten veranderingen op de toekomst van de wereld?
