While the fights and fumbles over the Affordable Care Act dominated headlines in 2013, the year was also heady with advances in biomedicine. In April, President Obama announced an ambitious federal initiative to map the activity of all the neurons in a brain circuit or, ideally, a whole brain. The $100 million Brain Research through Advancing Innovative Neurotechnologies (BRAIN) project will support neuroscientists, nanotechnologists, and others who propose to develop new technologies that can monitor thousands of neurons simultaneously.
The hope is that such new innovations could help neuroscientists understand the biological origin of cognition and perception and speed the development of treatments for disorders such as autism or post-traumatic stress disorder. There was remarkable progress in the field of neuroscience this year, but researchers still struggle to understand and treat the brain.
