Lab Rotation 1

Modeling the coexistence of different brain oscillations

Team Leader: Alain Destexhe

Supervisor:  Alain Destexhe

Period: From September 05th to December 05th

The long-term goal of this project is to understand how and why the same types of oscillations are seen in the brain, as well as in different animals.  Do they play a fundamental role in information processing?  

Alain Destexhe's group already have models (cortical or thalamo-cortical) for slow oscillation types such as delta and spindle oscillations.  Also there exists many proposed mechanisms to generate oscillations, for example based on excitatory-inhibitory loops, or loops between inhibitory cells, etc.

One possibility in this short term project is to identify elementary circuits that create a "resonance" at key frequencies (such as the "fast" gamma oscillations at 40 Hz for example) and then add this elementary circuit in network models. Something that would allow to see under which conditions the network could generate these oscillations (and possibly switch between oscillation types). 

This type of model could be directly compared to recordings made in human subjects during the wake-sleep cycle (work done in collaboration with the Human Brain Project and the European Institute of Theoretical Neuroscience in Paris).
