In our interaction with our environment we constantly refer to past experiences stored as memories to guide behavioral decisions. But how memories are formed, stored and then retrieved to assist decision-making remains a mystery. By observing whole-brain activity in live zebrafish, researchers from the RIKEN Brain Science Institute have visualized for the first time how information stored as long-term memory in the cerebral cortex is processed to guide behavioral choices. http://medicalxpress.com/news/2013-05-visualize-memory-formation-zebrafish.html Neuroscience Thu, 16 May 2013 12:00:01 EST news287923163 Children who avoid situations they find scary are likely to have anxiety a Mayo Clinic study of more than 800 children ages 7 to 18 found.
