• When your eyes override your ears: New insights into the McGurk effect

  16-02-2017 20:39
  Seeing is not always believing -- visual speech (mouth movements) mismatched with auditory speech (sounds) can result in the perception of an entirely different message. This mysterious illusion is known as the McGurk effect. Neuroscience researchers have created an algorithm to reveal key insight into why the brain can sometimes muddle up one of the most fundamental aspects of the human experience.

• Targeted radiosurgery better than whole-brain radiation for treating brain tumors

  16-02-2017 19:03
  Tumors that originate in other organs of the body and spread to the brain are known as metastatic brain tumors. According to the American Brain Tumor Association, this tumor type is the most common in adults, affecting as many as 300,000 people each year. Researchers compared two common postsurgical therapies for metastatic brain tumors and found that stereotactic radiosurgery can provide better outcomes for patients compared to whole-brain radiation.

  Ultra-flexible, nanoelectronic thread (NET) brain probes have been designed that can achieve more reliable long-term neural recording than existing probes and don't elicit scar formation when implanted. These smaller-than-a-capillary-sized probes could provide the reliable brain interface needed to control prosthetics, or follow the progression of neurodegenerative diseases.
