Researchers have gained a new understanding of how the brain processes reward and risk information. Neuroscientists show how nerve cells in the so-called amygdala not only encode the probability and magnitude of rewards, but also dynamically process this information to predict value and risk. The findings provide new insights into the neural basis of decision-making and could also be important for understanding mental illnesses such as anxiety disorders and depression.
