The Seventh International Symposium on “Biology of Decision Making” (SBDM) will take place on May 14-16, 2017 in Bordeaux, France. The objective of this three-day symposium will be to gather people from different research fields with different approaches (economics, ethology, psychiatry, neural and computational approaches) to decision making. The conference will include five sessions on habitual decision-making, beliefs and decision-making, dynamics of decision-making, boise and variability in decision-making, hormones and decision-making. I’ll give an invited talk on “Noise as a symmetry breaker”.
