  • The immobility response is an innate antipredatory behavior in a broad variety of species. The immobility response varies in its postural components but in general is characterized by an absence of movement and a relative unresponsiveness to stimuli. Experimentally in rats, clamping the neck followed by body inversion and manual restrain elicits a response called "immobility by clamping the neck". Stress reactions protect animals against predators and are characterized by activation of the… CONTINUE READING
