Anticipation is a universal preparatory response essential to the survival of an organism. Although meta-analytic synthesis of the literature exists for the anticipation of reward, a neuroimaging-based meta-analysis of the neural mechanisms of aversive anticipation is lacking. To address this gap in the literature, we ran an activation likelihood estimate ALE meta-analysis of 63 fMRI studies of aversive anticipation across multiple sensory modalities.

Fear is an emotion induced by perceived danger or threat , which causes physiological changes and ultimately behavioral changes, such as mounting an aggressive response or fleeing the threat. Fear in human beings may occur in response to a certain stimulus occurring in the present, or in anticipation or expectation of a future threat perceived as a risk to oneself. In humans and other animals, fear is modulated by the process of cognition and learning. Thus, fear is judged as rational or appropriate and irrational or inappropriate. An irrational fear is called a phobia.
Tsafrir Greenberg, Joshua M. The neural correlates of anxious anticipation have been primarily studied with aversive and neutral stimuli. In this study, we examined the effect of valence on anticipation by using high arousal aversive and positive stimuli and a condition of uncertainty i. Anticipation of all affective clips engaged common regions including the anterior insula, dorsal anterior cingulate cortex, thalamus, caudate, inferior parietal and prefrontal cortex that are associated with emotional experience, sustained attention and appraisal. These results suggest that a common circuitry is recruited in anticipation of affective clips regardless of valence, with additional areas preferentially engaged depending on whether expected stimuli are negative or positive.
During self-control, we may resist short-term temptations in order to reach a favorable future e. Here, we investigate the neural underpinnings of regulating cravings by mentally evoking the positive consequences of resisting a temptation e. It is conceivable that when using these types of strategies, regions associated with emotional processing [e. Thirty-one participants saw pictures of unhealthy snacks in the fMRI scanner and, depending on the trial, regulated their craving by thinking of the positive consequences of resisting, or the negative consequences of not resisting. In a control condition, they anticipated the pleasure of eating and thus, allowed the craving to occur now-condition. In line with previous studies, we found activation of a cognitive control network during self-regulation.
Rumination — as a stable tendency to focus repetitively on feelings related to distress — represents a transdiagnostic risk factor. Theories suggest altered emotional information processing as the key mechanism of rumination. However, studies on the anticipation processes in relation to rumination are scarce, even though expectation in this process is demonstrated to influence the processing of emotional stimuli. In addition, no published study has investigated violated expectation in relation to rumination yet.

Она услышала, что в кабине работает вентиляция. Лифт. Почему же не открывается дверца. Вглядевшись, она как в тумане увидела еще одну панель с буквами алфавита от А до Z и тут же вспомнила, что нужно ввести шифр. Клубы дыма начали вытекать из треснувших оконных рам.
