It is now well established that vestibular information plays an important role in spatial memory processes. Although vestibular lesions induce anxiety in humans, this finding remains controversial in rodents. However, it is possible that anxiety-related behavior is associated with spatial memory impairments after vestibular lesions. We aimed to evaluate anxiety-like behavior and the effect of a...

In experimental psychopathology, construct validity is usually enhanced by addressing theories from other fields in its nomological network. In the field of anxiety research, this construct is related to antipredator behavior, conserved across phylogeny in its functions and neural basis, but not necessarily on its topography. Even though the relations between behavioral models of anxiety and st...

BACKGROUND Thigmotaxis refers to a specific behavior of animals (i.e., to stay close to walls when exploring an open space). Such behavior can be assessed with the open field test (OFT), which is a well-established indicator of animal fear. The detection of similar open field behavior in humans may verify the translational validity of this paradigm. Enhanced thigmotaxis related to anxiety may s...

The neurobiological bases of mood disorders remain elusive but both monoamines and neuropeptides may play important roles. The neuropeptide cocaine and amphetamine regulated transcript (CART) was shown to induce anxiety-like behavior in rodents, and mutations in the human CART gene are associated with depression and anxiety. We measured CART-like immunoreactivity (-LI) in genetic rat models of ...

Background & Aims: Motherhood has been taken into account as an enjoyable and evolutionary event in women’s life, however, because of physical and mental changes; it can cause some degrees of stress and anxiety. The present study aimed to examine the effects of cognitive-behavior stress management (CBSM) training on the levels of anxiety and depression during the pregnancy. Methods: This was a ...

the present study aimed to investigate the effectiveness of group cognitive behavioral therapy in reducing anxiety and depression and glycemic control in children with type i diabetes. the study was quasi- experimental with a pre-test, post-test design with control group. for this purpose, 30 children with diabetes were selected from imam reza hospital in mashhad. the children were randomly ass...

The role of affective dimension in the postoperative pain is still poorly understood. The present study investigated the development of anxiety-like behavior and amygdala sensitization in incisional pain. Using hind-paw incision model in rats, we showed that surgical incision induced the anxiety-like behavior as determined by elevated plus-maze and open-field tests. Intraperitoneal (IP) morphin...
