So how does the tech want to reprogram our memories? Light, holograms, VR or neural chips: Guillaume Grallet tells us why brain specialists play with our memory.

This is a real feat that Grenoble scientists have realized. The Clinatec Research Center has developed an exoskeleton that allows a quadriplegic patient to move. Electrodes implanted in his brain, help him to control it.

"A scent arouses thought" - the phrase is from Victor Hugo. This time, it's the thought that awakens the scent, thanks to techs like no other. Guerlain has called on Franky Trichet, a neuroscientist, to help us find our next fragrance. With a headset whose electrodes capture the activity of the brain, just 15 seconds, watch in hand, to build your olfactory profile. Demostration in plateau.
