Tonic Immobility as an Evolved Predator Defense: Implications for Sexual Assault Survivors

This article reviews research concerning the possible relationship between tonic immobility (TI) and human reactions to sexual assault. This review includes a description of the characteristic

Geotropic, hydrokinetic and random walking differ between sympatric tick species: the deer tick Ixodes scapularis and the lone star tick Ambylomma americanum

The assessment of behavioral distinctness between these sympatric species will facilitate the design of experiments aimed at evaluations of attractants and repellents, and contribute to biorational control and surveillance strategies.

Lateralized motor behaviour in the righting responses of the cane toad (Rhinella marina)

In contrast to the expectation that handedness in toads represents intentional or voluntary preferences, the presence of lateralized central pattern generators in the toads is postulated to explain the different forms of lateralization revealed by tests.

A cerebellar-prepontine circuit for tonic immobility triggered by an inescapable threat

It is demonstrated that a strong vibratory stimulus evokes tonic immobility in larval zebrafish defined by suppression of exploratory locomotion and sensorimotor responses, and cerebellar regulation of a neuropeptide-rich prepontine structure governs a conserved and ancestral defensive behavior triggered by inescapable threat.

Hemodynamics of tonic immobility in the American alligator (Alligator mississippiensis) identified through Doppler ultrasonography

It is hypothesized that inverting the alligator causes a gravitationally promoted increase in right aortic blood flowing through the foramen of Panizza, with a concurrent decrease in blood flow through the primary carotid, and thereby of cerebral perfusion.

Movement Patterns of Sphyrna tiburo (Bonnethead Shark) in a Shallow Tidal Creek System

Abstract The purpose of this study was to use acoustic telemetry to elucidate the small-scale habitat-utilization patterns of Sphyrna tiburo (Bonnethead Shark, hereafter, Bonnethead) in relation to

Tonic immobility as an anaesthetic for elasmobranchs during surgical implantation procedures

It is identified that tonic immobility provides an effective anaesthetic for surgical implantation in elasmobranchs, as it offers several benefits over chemical anaesthetics, both from a practical and from an animal welfare perspective.

Population structure, spatial distribution and life-history traits of blacktip reef sharks Carcharhinus melanopterus.

The C. melanopterus population at Moorea showed an apparent spatial sexual segregation with females preferentially frequenting lagoons and males the fore-reefs, confirming high geographic variability in the population structure of the species.

Removal of an Intracoelomic Hook via Laparotomy in a Sandbar Shark (Carcharhinus plumbeus)

Abstract:  A twenty-one-year-old male sandbar shark (Carcharhinus plumbeus) demonstrated signs of chronic weight loss even though its appetite remained unchanged. In addition, the gradual development



Behavioral Responses Associated with Animal Hypnosis

Evidence of the present and previous research is consistent with the concept that animal hypnosis could serve as an experimental model of human hypnosis, as well as a lack of residual effect from the hypnosis.

The Mechanism of Tonic Immobility (“Animal Hypnosis”)

Resume On donne la description du phenomene de l'immobilite tonique, appelee frequemment “l'hypnose animale,” ou “faisant le mort.” On discute cet etat au point de vue de sa signification biologique

The tonic immobility reaction in chickens: Response characteristics and methodology

The optimal period of manual restraint, by way of producing the most durable immobility response, was found to be 15 sec, and pretest holding conditions were shown to exert a significant influence on the reaction in naive birds.

Der Einfluß der Zahmheit auf die sogenannte „tierische Hypnose” bei Vögeln1

Dies ist in dem Sinne zu verstehen, das der psychologisch oder physiologisch gesehene Angstzustand der Tiere, nach der Zahmung durch die Annaherung eines Menschen nicht mehr ausgelost wird.
