Immobility reactions under threat : a contribution to human defensive cascade a...
Volchan, Eliane; Rego, Vanessa da Rocha; Campos, Aline Furtado Bastos; Oliveira, José Magalhães de; Franklin, Camila Martins; Gleiser, SoniaViolence exacts a burden on public health. Gun violence is a major trigger for motor defensive reactions in humans and post-traumatic stress disorder (PTSD) is its main psychiatric sequela. However, studies of the human defensive cascade, especially the motor reactions, are at an early stage. This review focuses on studies that employ stabilometry, a methodology that assesses whole body motor reactions, to addr...
Is there tonic immobility in humans? Biological evidence from victims of trauma...
Volchan, Eliane; Souza, Gabriela Guerra Leal de; Franklin, Camila Martins; Norte, Carlos Eduardo; Rego, Vanessa da Rocha; Oliveira, José Magalhães deTonic immobility, characterized by profound motor inhibition, is elicited under inescapable threat in many species. To fully support the existence of tonic immobility in humans, our aim was to elicit this reaction in a laboratory setting and measure it objectively. To mimic exposure to life-threatening events in the lab, trauma-exposed participants with PTSD (n = 18) and without PTSD (n = 15) listened to the sc...
