Our two teams involved in ERC fUSimagine, led by Ivan Cohen from Inserm Unit 1130 “Neuroscience Paris Seine” and Mickaël Tanter from Inserm Unit 979 “Wave physics for medicine” at the Langevin Institute (ESPCI/CNRS) have improved the fUS method to make it portable and usable with conscious and mobile rats at the same time as an EEG.In order to demonstrate the benefits of this new method for pathological applications, the researchers looked at cerebral mechanisms in rats that reproduce epileptic seizures.
“Thanks to this cutting-edge technology, we have precisely observed changes in blood flow which are precursors of epileptic seizure onset“, explains Inserm Research Fellow Ivan Cohen.
A study of cerebral mechanisms of mobile animals offers multiple opportunities for understanding behaviour and neurological conditions by mapping the regions of the brain associated with them. In particular, this technology will allow us to combine neurological and vascular data that play a key role in conditions such as dementia, strokes, epilepsy and Alzheimer’s disease.
