Brain Fuel provides a space for PhD students and PostDocs of the Paris Brain Institute to present their most recent data. The goal of this internal event is to exchange feedback between speakers and experts within the Institute's community.


This event takes place every month, on Tuesdays, during lunchtime. Food and drinks are provided by the Ajités. The organizer of this event is Daniela Domingues.

Join the community!


If you are interested in participating as a speaker or helping in the organization, please contact Daniela!

The story of overworked mitochondria: Importance of calcium homeostasis in axonal mitochondria

You all might have heard it at some point- Mitochondria is the powerhouse of the cell! This is even more so in neurons. Neurons are by nature very active and highly dynamic - a lot can change very quickly! Therefore, in order to function well they also need their mitochondria to co-ordinate and keep up with them. Previously, it has been shown that during activity, axonal cytosolic calcium and its import into the mitochondria is required and central to this coordination. But what about mitochondrial calcium export? Is this important for neuronal function? If so, how?


In this project, we explore these questions (stumbling upon surprising results) combining genetic and optical tools with electrophysiological stimulation.

Scientists' Actions Against Climate Change

The worldwide scientific community is at the forefront of understanding the ecological crisis, its anthropic origins, and ways to mitigate it and cope with it. But the immensity of the task, the complexity of the subject matter, and the felt lack of impact of individual actions are discouraging many in the scientific community. Many... but not all. Scientists are taking individual and collective actions to change their practice, and adapt to the upcoming new reality. This is an overview.

Activity-driven synaptic translocation of LGI1 controls excitatory neurotransmission

I developed novel optical tools to visualize in firing synapses the molecular behavior of a particular secreted trans-synaptic protein, LGI1, and its presynaptic receptor, ADAM23. I found that LGI1 in synapses was not secreted, as described elsewhere, but exo- and endocytosed through its interaction with ADAM23. Activity-driven translocation of LGI1 facilitated the formation of trans-synaptic connections proportionally to the history of activity of the synapse, modulating excitatory transmission. My findings reveal that LGI1 abundance at the synaptic cleft can be acutely remodeled and serves as a critical point of activity-dependent control of synaptic function.
