Every movement we make requires our brains to predict what forces–gravity, an object we’re holding, a strong gust of wind–each of our body 
parts will experience in order to move in a coordinated fashion. No movement is ever exactly the same and so it is remarkable that we are not constantly tripping over ourselves. It is well-known that humans learn based on previous errors in their movements. My work at the Harvard Neuromotor Control Lab was to investigate how the brain learns to “makes generalizations” about movements and learn from its mistakes. Continue reading
Each year, half a million patients present to emergency departments in the US with acute vestibular syndrome (AVS) characterized by vertigo lasting more than 24 hours.
