"A new ultrasound imaging technique has provided the first ever in vivo visualization of activity in the piriform cortex of rats during odor perception.. This deep-seated brain structure plays an important role in olfaction, and was inaccessible to functional imaging until now. This work also sheds new light on the still poorly known functioning of the olfactory system, and notably how information is processed in the brain. This study is the result of a collaboration between the team led by Mickael Tanter at the Institut Langevin (CNRS/INSERM/ESPCI ParisTech/UPMC/Universit\u00E9 Paris Diderot) and that led by Hirac Gurden in the Laboratoire Imagerie et Mod\u00E9lisation en Neurobiologie et Canc\u00E9rologie (CNRS/Universit\u00E9 Paris-Sud/Universit\u00E9 Paris Diderot). Their findings are published in NeuroImage dated July 15, 2014."^^<http://www.w3.org/2001/XMLSchema#string>
