Re-mapping the brain… Moving mountains…
Targeted motor and sensory reinnervation (TMSR) is a surgical procedure on patients with amputations that reroutes residual limb nerves towards intact muscles and skin in order to fit them with a limb prosthesis allowing unprecedented control. By its nature, TMSR changes the way the brain processes motor control and somatosensory input; however, the detailed brain…

Hungry brain… Thirsty soul…
For years, scientists assumed that humans devote a larger share of their daily calories to their brains than other animals. Although the human brain makes up only 2 percent of body weight, it consumes more than 25 percent of our baseline energy budget. But a study published Oct. 31, 2017 in the Journal of Human…

Forgetting. Thus, being able to think.
Even as the power of our modern computers grows exponentially, biological systems - like our brains - remain the ultimate learning machines. By finding materials that act in ways similar to the mechanisms that biology uses to retain and process information, scientists hope to find clues to help us build smarter computers. Inspired by human…

Time standing still…
Quickly glance at an analog clock. You might find that the second hand seems stuck at first. But if the precise machinery ensures every second is the same, why the pause? Amelia Hunt, a neuroscientist with the University of Aberdeen in Scotland, says the standstill (nicknamed the stopped-clock illusion) occurs because our brains anticipate what…

Training machines to listen. Life. Tautologies.
Brain-computer interfaces, known as BCI, can replace bodily functions to a certain degree. Thanks to BCI, physically impaired persons can control special prostheses through the power of their minds, surf in internet and write emails. Under the title of "Brain Composer," a group led by BCI expert Gernot Müller-Putz from TU Graz's Institute of Neural…
