Fig. 9: Probabilistic foraging task in gerbils.
From: Differential patch-leaving behavior during probabilistic foraging in humans and gerbils
a Schematic illustration of the foraging task in which gerbils can access food from two ‘Foraging spouts’ 1 and 2, located at the opposite ends of the box. b Scheme indicates the animals’ foraging behavior as a function of time. Color-coded circles in gray horizontal bars indicate the nose pokes at spout 1 (orange) and spout 2 (green) during an experimental session. Trial duration: A trial started with the first breaking of the light barrier by a nose poke lasting more than 100 ms (hit) at one spout and ended with a first poke at the opposite spout. The residence time per spout was defined as the duration between trial start and end. The last release of a poke in each trial marked the beginning of the following travel time that corresponds to the time until the hit poke at the opposite spout occurred.
