SUMMARY:Iain D. COUZIN (Max Planck Institute of Animal Behavior\, Konstanz\
 , Germany): Geometrical Principles of Decision-Making on the Move
DESCRIPTION:Iain D. COUZIN: A central challenge for animals when alone\, or
  when grouping with others\, is deciding where to go. Running\, swimming\,
  or flying through the world\, animals are constantly making decisions whi
 le on the move—decisions that allow them to choose where to eat\, where 
 to hide\, and with whom to associate. Despite this most studies have consi
 dered only on the outcome of\, and time taken to make\, decisions. Motion 
 is\, however\, crucial in terms of how space is represented by organisms d
 uring spatial decision-making. Employing a range of new technologies\, inc
 luding automated tracking\, computational reconstruction of sensory inform
 ation\, and immersive ‘holographic’ virtual reality (VR) experiments w
 ith fruit flies\, locusts and zebrafish (representing aerial\, terrestrial
  and aquatic locomotion\, respectively)\, I will demonstrate that this tim
 e-varying representation results in the emergence of new and fundamental g
 eometric principles that considerably impact effective decision-making. Sp
 ecifically\, we find that the brain spontaneously reduces multi-choice dec
 isions into a series of abrupt (critical) binary decisions in space-time\,
  a process that repeats until only one option—the one ultimately selecte
 d by the individual—remains. This mechanism facilitates highly effective
  decision-making\, and is shown to be robust both to the number of options
  available\, and to context\, such as whether options are static (e.g. ref
 uges) or mobile (e.g. other animals). In addition\, we find evidence that 
 the same geometric principles of decision-making occur across scales of bi
 ological organisation\, from neural dynamics to animal collectives\, sugge
 sting they are fundamental features of spatiotemporal computation.\nIOSSB
