The Eleventh Symposium on Biology of Decision Making (SBDM 2023) took place on June 1-2, 2023.

The objective of this two-day symposium is to gather people from different research fields with different approaches (economics, ethology, psychiatry, robotics, neural and computational approaches) to decision making.

Recordings of the talks are available on the SBDM 2023 playlist of the SBDM YouTube channel.
