Canine electrode locations and data segments. (A) For the canine subjects, bilateral pairs of 4-contact strips were implanted oriented along the anterior-posterior direction. Electrode wires were tunnelled through the neck and connected to an implanted telemetry device secured beneath the latissimus dorsi muscle. (B) An hour of data with a 5-min offset before each lead seizure was extracted and split into 10-min segments for analysis. (C) The expanded view illustrates a ∼35-s long seizure.

It might sound like a riddle: What do you get when you combine 1 online contest, 2 patients, 5 five dogs and 654 data scientists? The answer: Hope for patients with epilepsy that their seizures can be reliably predicted, and perhaps prevented...

A computer in the lab of Miguel Nicolelis, M.D., Ph.D., monitors brain signals from a rhesus macaque. Nicolelis and Duke researchers record signals from hundreds of neurons in two regions of the monkeys’ brains that are involved in movement and sensation. As the animals think about moving toward their goal — in this case, a bowl containing fresh grapes — computers translate their brain activity into real-time operation of a wheelchair.

Neuroscientists have developed a brain-machine interface (BMI) that allows primates to use only their thoughts to navigate a robotic wheelchair. The BMI uses signals from hundreds of neurons recorded simultaneously in 2 regions of the monkeys’ brains that are involved in movement and sensation...
