Given records of the simultaneous activity of a set of neurons, how can we infer the interactions between neurons in that set?
Science / Mathematics
Thanks to recent technological advances, recordings of the simultaneous neural activity of tens to thousands of neurons exposed to different external stimuli, such as visual images and sounds, are now abundant. Even though they are numerous, the neurons observed correspond to a tiny portion of the cortex. It’s as if we only see the tip of a huge iceberg. In this context, the project’s objective is to develop a set of mathematical and computational tools that allow us to answer questions such as: How to infer and interpret interactions between neurons, given that we always observe a few neurons embedded in a huge network? How do these interactions change depending on the external stimulus?
