Beginning in the 1940s, Canadian brain surgeon Wilder Penfield mapped the brain's motor cortex -- the area that controls the movement of your body's muscles. Now you can relive his exploration of the brain.

Neurons are highly specialized cells that conduct and process information in animals, enabling thought, perception and control of movement. Lydia Harriss presents a quick guide to these remarkable cells.

Glial cells provide insulation for nerve cells and help them communicate with one another. Using mouse muscle nerves, scientists studied the role of specific proteins in the growth of these cells.

3D reconstructions reveal the detailed anatomy of three types of neurons in a mouse's cerebellum, an area of the brain that helps control movement.

Every morning we wake up and regain consciousness, but what exactly is it that we regain? Neuroscientist Antonio Damasio uses this question to give us a glimpse into how our brains create our sense of self.
