The National Science Foundation (NSF) sponsors a great deal of research on neuroengineering that may affect how we understand conditions such as epilepsy. This website explores some of those innovations and visitors can watch videos and view examples of how different technologies are being used to understand the brain's operations. The site contains five sections, including Exploring the Neuro-realm and Beyond the Brain. Visitors can learn about electronic tattoos that can monitor the brain, heart and muscles, along with remarkable innovations such as artificial retinas and lasers that can manipulate neural signaling. Additionally, the site includes a short video that explores the complexities and promise of brain research through the insights of three engineers. The site is rounded out by a clutch of related websites, including the NSF Understanding the Brain and brainfacts.org.
