Research Highlight : Ultrasound tracks odor representation in brain

ENP team leader Hirac Gurden and his collaborators used a new ultrasound imaging technique and 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. Their work also sheds new light on the still poorly known functioning of the olfactory system, and notably how information is processed in the brain.   Source and details on Science Daily
