Spindles “shut off” prefrontal cortex from hippocampal input

We are able to acquire new memories, and to maintain them, thanks to the interaction between multiple brain areas that work together to process, filter, and store information. As we experience a new situation, a memory trace of this episode is formed in a structure deeply buried underneath the cerebral cortex: the hippocampus. The hippocampus [...]

Brain Research (the journal)

Since last January, I’ve been serving on the editorial board of the journal Brain Research, under the guidance of the new editor-in-chief Dr. Irwin Levitan, as one of the Senior Editors for the section “Cognition and Computation”. It has been a very interesting experience so far. If you have ideas about possible special issues on [...]

Oscillation in the prefrontal cortex

            Together with Karim Benchenane and Paul Tiesinga, we wrote a review for Current  Opinion in Neurophysiology, trying to highlight the common patterns between the mechanisms of the theta and gamma rhythms in the prefrontal cortex, and their consequences for prefrontal functions, in particular, long-term memory, and attention.   Benchenane [...]

Cell assemblies, coherence in oscillations, and information selection

Our brain is presented with a constant stream of experience: a huge amount of information, too much to be stored in full in our memory. How can we keep only the essential parts of this stream? This is the questions that UvA and CNRS-Collège de France have attempted to answer. The hippocampus and the prefrontal [...]

“Replay spikes” in the prefrontal cortex reflect learning, and the hippocampal input

During sleep, memories about our previous experience are replayed, as was previously shown in the hippocampus, in the neocortex and in the striatum. This replay is probably important for memory consolidation, the process of stabilization of memories that is thought to be orchestrated by the hippocampus. With Adrien Peyrache, Karim Benchenane, Mehdi Khamassi, and Sidney [...]

“Brain and cognition” at Physics@FOM, Veldhoven, Netherlands

The Dutch foundation for “fundamental research on physics of the matter” had its meeting in Veldhoven on Januray 20-21. Stan Gielen and Michel Decré organized a symposium on brain and cognition that saw a pretty interested audience. I was very honored to be invited to speak in this panel, and hope that it will help [...]

MATLAB code for data analysis

I have started sharing my MATLAB code here. More information later.

Fridtjof Nansen conference on Neural Networks and Behaviour

From the 4th to the 8th of June the  Fridtjof Nansen conference on Neural Networks and Behaviour took place on the Norwegian island of Spitsbergen, in the Svalbard archipelago (79 degrees North). The conference was organized by Edvard Moser, May-Britt Moser, and Menno Witter from the Center for the Biology of Memory in the Norwegian [...]
