Predictors of tonic immobility during traumatic events
Título: Predictores de la inmovilidad tónica ante eventos traumáticos. Resumen: La inmovilidad tónica (IT) es una posible reacción ante el peligro que es facilitada por el miedo intenso, la restricción física y la incapacidad percibida de escapar. Otras variables que podrían influir, tales como el tipo de eventos traumáticos, características de los mismos y características personales han sido p...
متن کاملTraumatic events and tonic immobility.
Tonic immobility is a basic defense strategy which has not been studied in depth in humans. Data suggest that it may be a relatively frequent phenomenon in victims of rape and sexual abuse, but its occurrence has not been systematically explored in other types of trauma. We carried out a retrospective study in a sample of 100 university students to establish whether tonic immobility varies depe...
متن کاملShort Copy Number Variations Potentially Associated with Tonic Immobility Responses in Newly Hatched Chicks
INTRODUCTION Tonic immobility (TI) is fear-induced freezing that animals may undergo when confronted by a threat. It is principally observed in prey species as defence mechanisms. In our preliminary research, we detected large inter-individual variations in the frequency and duration of freezing behavior among newly hatched domestic chicks (Gallus gallus). In this study we aim to identify the c...
متن کاملCholinergic blockade and tonic immobility in chickens
To investigate the effects of cholinergic blockade on duration of tonic immobility (TI) and habituation to handling and the TI testing procedure, two groups of cockerel chicks were tested following injection with scopolamine or saline. One week later half of each group was given a second test for TI following injection with saline or scopolamine. Results indicated that scopolamine significantly...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
