This project is part of an ANR-funded program (SniffAttention) in which we propose to use the olfactory modality, a dominant sense for rodents, to study attention in rats. One of the aims of this project is to decipher the neural network involved during a sustained olfactory attention task in rodents. We also want to test the hypothesis that respiration can serve as an effective metronome to synchronize the areas of this neural network. To answer these questions, we combine behavioral experiments in rats, multi-site local field potentials recordings (simultaneously in the piriform cortex, mediodorsal thalamus …) and respiration recording (using a whole-body plethysmograph).
