Effect of Detainment on Extinction of Avoidance Responses.

چکیده

Following shuttle-box avoidance training, 10 rats were assigned to each of 6 groups, matched on the basis of trials to acquisition criterion. During extinction, Ss were detained in the presence of the CS for intervals of 0-20 sec. before being allowed to perform the avoidance response. The rate of extinction increased with the duration of detainment. The results are interpreted in terms of both "conservation of anxiety" and counterconditioning.

Effect of WIN55-212-2 and Consequences of Extinction Training on Conditioned Fear Memory in PTSD Male Rats

Introduction: This study investigates the effects of cannabinoid agonist WIN55-212-2 on acquisition and consolidation phases of the fear memory extinction and also on anxiety and motor activity. Methods: In this study, we used SPS & S model to induce post-traumatic stress disorder. One week after SPS, to establish a conditioned fear memory, rats received an electric foot shock within shock cha...

Differential effects of inactivation of the right and left basolateral amygdala on spatial memory in place avoidance task in rats

There is strong evidence that two cerebral hemispheres are differentially involved in emotional memory and that amygdala is a key subcortical structure for emotional experience. The present research investigated the possible involvement of lateralization of basolateral amygdala (BLA) and central amygdala (CEA) in place avoidance memory. For this purpose, male Long-Evans rats (280-320 g) were im...

بررسی اثر حذف برگشت پذیر هسته‌ قاعده‌ای‌ جانبی‌ آمیگدال‌ در فرآیند حافظه‌ فضایی‌ وابسته به هیپوکمپ در موش‌ آزمایشگاهی ‌

Introduction: Many evidences have suggested that the Basolateral Amygdala (BLA) are probably involved in emotional learning and modulation of spatial memory processes. The aim of this present study was assessment of the effect of reversible abolition of BLA on spatial memory processes in a place avoidance learning model in a stable environment. Methods and Materials: Long-Evans strain rats (28...

Reductions in Children's Vicariously Learnt Avoidance and Heart Rate Responses Using Positive Modeling.

Recent research has indicated that vicarious learning can lead to increases in children's fear beliefs and avoidance preferences for stimuli and that these fear responses can subsequently be reversed using positive modeling (counterconditioning). The current study investigated children's vicariously acquired avoidance behavior, physiological responses (heart rate), and attentional bias for stim...

Active Avoidance: Neural Mechanisms and Attenuation of Pavlovian Conditioned Responding.

Patients with anxiety disorders often experience a relapse in symptoms after exposure therapy. Similarly, threat responses acquired during Pavlovian threat conditioning often return after extinction learning. Accordingly, there is a need for alternative methods to persistently reduce threat responding. Studies in rodents have suggested that exercising behavioral control over an aversive stimulu...
