Brain Activity Revealed Through Your Skin: Stress, Sleep, & Seizures | Rosalind Picard | TEDxNatick

While using a wristband to measure stress in a person who could not speak, Picard, a scientist and professor at the MIT Media Lab, measured an unusual signal on the surface of the skin -- revealing unexpected connections between electrical activity deep in the brain and changes that show up on the wrist during stress, sleep, seizures, and dangerous periods following seizures, which can lead to sudden unexpected death in epilepsy, called SUDEP. You might help save a life by learning about these findings and sharing them with people you know.

Rosalind is a professor at the MIT Media Lab. She is credited with starting the field of Affective Computing, giving computers emotional intelligence. She also developed the first wearables that sense affective data and can help people with epilepsy, autism, and too much stress in their lives. Her inventions have led to start-up companies such as Affectiva and Empatica.
