The tonic immobility (TI) response is an innate fear behavior associated with intensely
dangerous situations, exhibited by many species of invertebrate and vertebrate animals. In …

Tonic immobility (TI) is a temporary state of profound motor inhibition induced by situations
that generate intense fear, with the objective of protecting an animal from attacks by …

The aim of the present study is to test a hypothesis that 5-HT1A and 5-HT2C receptors in the
amygdala play an important role in the regulation of anxiety behaviors. We examined …

Tonic immobility (TI), also known as death feigning or animal hypnosis, is a reversible state
of motor inhibition that is not only triggered by postural inversion and/or movement …

Tonic immobility (TI) is an innate defensive behavior characterized by a state of physical
inactivity and diminished responsiveness to environmental stimuli. Behavioral adaptations to …

Tonic immobility (TI) is an inborn defensive behavior characterized by a temporary state of
profound and reversible motor inhibition elicited by some forms of physical restraint. We …

In order to investigate the role of the 5-HT1A receptors of the amygdala in modulating
anxiety, rats were implanted with bilateral cannulae aimed at the basolateral nucleus of the …

Interactions between the prelimbic cortex and the basolateral amygdala underlie fear
memory processing, mostly through acquiring and consolidating the learning of a …

Changes in 5-HT1A receptor-mediated neurotransmission at the level of the median raphe
nucleus (MRN) are reported to affect the expression of defensive responses that are …

Previous evidence has shown that facilitation of GABA/benzodiazepine-mediated
neurotransmission in the ventromedial hypothalamus (VMH) inhibits both escape and …
