Research Highlight:Spatial Navigation
ENP team leader Laure Rondi-Reig continues to help us find our way: more advances in understanding how the brain navigates a space. Céline Fouquet and Bénédicte M. Babayan, members of Rondi-Reig’s team, found that the dorsal part of the hippocampus appears to be important to organize the sequence of one's own body movements along a route. The dorsomedial striatum also appears to play a significant role: lesioning this region completely prevented the mice from learning the navigation task!
