A new grant of 10,000 € by the University of Bordeaux to co-organise a hands-on worshop on neuroanatomy and tractography with the Anatomical institute in Munich
Neurosciences are making enormous strides now that there are advanced sequences available from magnetic resonance imaging (MRI) scanners. Thanks to these new techniques, we have learned quite a lot about the underlying structure of human cognitive functions. The use of neuroimaging data in cognitive and clinical studies is facilitated by the use of brain atlases. However, the human brain is highly variable and a strong anatomical understanding is essential to accurately read brain images and draw the correct conclusions for cognitive and clinical studies. One of the significant advantages of using neuroimaging to study brain anatomy is that it has vastly accelerated our gain of knowledge due to the possibility to scan large numbers of people (e.g. healthy volunteers or patients) and find coherent patterns in their architecture of the brain. Classical anatomical studies used to be conducted on post mortem specimens, which naturally and ethically limits the number of brains that can be studied. The unique advantage of postmortem studies is however the hands-on 3-dimensional understanding of the individual parts of the brain and how they interact with each other. As such, combining postmortem anatomical dissections with MRI-based neuroimaging methods offers a unique insight into the structure and function of the brain.
In combination with our colleagues in Munich we are organising a integrative neuroanatomy course to bring together the advantages of neuroimaging and postmortem anatomy. This combination makes our course the first of its kind in the world and offers the most comprehensive course on white matter anatomy.
If things go south, we are planning to do it online. If things work smoothly the plan is to hold one workshop in Bordeaux in 2021 and another workshop will be organised in Munich before or after the winter semester in 2021/2022. The venue will be the Laboratoire d’anatomie at the University of Bor- deaux and the Anatomical Institute in Munich.

Neurosciences unlock the secret of the first abstract engravings
Long before Lascaux paintings, humans engraved abstract motifs on stones, shells or egg shells. the earliest are 540,000 years old. For the archaeologists who discovered these objects, the question is whether they are the result of unpurposive behaviour, the simple Lire plus …

In search of the genetic basis of the cerebral lateralization of language through an innovative alliance between functional imaging and full genome sequencing
For the vast majority of human beings, it is the left hemisphere of the brain that is dominant for various aspects of language processing. Only less than 1% of the adult population has an atypical inverted dominance of their right Lire plus …

Nathalie Tzourio-Mazoyer among the women scientists of a photographic exhibition in the Basque Country
Worker Science is a project created by Teknahi to show realistically and closely working women in the world of science. The exhibition is a pilot sample of this international project, fruit of the collaboration between Teknahi and the Okendo Cultural Centre, which offers the public the possibility of getting closer to the day-to-day life of working women who do science in our society.
It is a proposal accessible to all audiences, thanks to the opposing visions of photographers Elba Martínez and Javier Domínguez, along with audiovisuals, infographics, texts and thematic showcases that will help us understand and enjoy the world of science, so present, so distant, and women who with their effort and knowledge improve our world every day, trying to make it less ignorant, less superstitious and less dark.
SENSAAS, a new atlas of the brain’s language areas
The GIN has just developed a new brain atlas of cortical areas of language integration. It will be particularly useful for cohort studies looking for the genetic bases of language regions or on the neuroanatomical changes associated with language pathology. Lire plus …
How to study structure-function relationships in the cerebral cortex? The development of new neuroimaging markers is a promising solution.
The Planum Temporale (PT) is a region of the temporal lobe involved in processing language sounds that has a larger surface area in the left cerebral hemisphere than in the right. Geschwind, who discovered this asymmetry in 1968, had proposed Lire plus …
