title: [Role of contact with a support in the tumbling response of white rats during free fall].
abstract: The tumbling and landing reactions of white rats were studied by cinematography during their free fall with eyes open. If the rats let the support go, they turned over and made a soft landing on their paws, no matter what their initial position was. However, when the animals fell down together with the support, the tumbling reaction was inhibited entirely and they landed as they were in the initial position, i.e. on the back, head, tail, etc. If during free fall the animals crumpled the support or if they touched a fixed object with their limbs or tail, they turned over and landed on their paws.
