“…Furthermore, our results are in agreement with the finding of amygdala involvement in the processing of relevant social stimuli. The amygdala has been shown to have direct influence on SCR (Bagshaw, Kimble, & Pribram, 1965;Laine et al, 2009) and to be particularly involved during direct gaze as compared to averted gaze perception in humans (George et al, 2001;Kawashima, et al, 1999). It is a likely candidate structure to mediate the influence of perceived direct gaze on arousal, particularly during the incidental processing of gaze (Critchley et al, 2000; see also Senju & Johnson, 2009).…”

Eye contact is a highly salient and fundamentally social signal. This entails that the mere perception of direct gaze may trigger differentiated neurobehavioral responses as compared to other gaze directions. We investigated this issue using a visual word-spelling task where faces under different gaze directions and head orientations were displayed on-screen concomitantly with the words. We show evidence for automatic increase of skin conductance response (SCR), indicative of arousal, associated with the perception of direct gaze as compared to both averted gaze and closed eyes. Moreover, the perception of averted gaze was associated with an increase of electromyographic (EMG) corrugator activity. These effects were observed in two demanding word-spelling tasks, but not in a simple letter decision task. We propose to interpret these findings in terms of the social value of direct and averted gaze and conclude that some circumstances such as the task at hand may be essential for uncovering the neurobehavioral responses associated with the perception of others' gaze.

“…In monkeys, removal of the amygdala decreases reactivity to sensory stimuli measured with the galvanic skin response. 97,98 In rodents lesions of the amygdala block conditioned changes in heart rate and blood pressure. Ablation of the amygdala can reduce the secretion of ACTH or corticosteroids as well as reducing stress-induced increases in dopamine release in the frontal cortex.…”

Here we provide a review of the animal and human literature concerning the role of the amygdala in fear conditioning, considering its potential influence over autonomic and hormonal changes, motor behavior and attentional processes. A stimulus that predicts an aversive outcome will change neural transmission in the amygdala to produce the somatic, autonomic and endocrine signs of fear, as well as increased attention to that stimulus. It is now clear that the amygdala is also involved in learning about positively valenced stimuli as well as spatial and motor learning and this review strives to integrate this additional information. A review of available studies examining the human amygdala covers both lesion and electrical stimulation studies as well as the most recent functional neuroimaging studies. Where appropriate, we attempt to integrate basic information on normal amygdala function with our current understanding of psychiatric disorders, including pathological anxiety. Molecular Psychiatry (2001) 6, 13-34.

“…The amygdala, which is an important part of the limbic system, is a brain structure critical for memory and is associated with certain psychological conditions, psychological behaviour [44], social behaviour [45] and neuroendocrine and autonomic function [46]. Amygdalectomy in monkeys has been demonstrated to attenuate or abolish electrodermal activity, which reflects psychological sweating in humans [47]. …”

Psychological sweating in response to emotive stimuli like stress, anxiety and pain occurs over the whole body surface, but is most evident on the palms, soles, face and axilla. This is primarily a consequence of high eccrine sweat gland densities at these body sites. Cholinergic innervation is the primary effector eliciting activation of eccrine sweat glands during periods of acute psychological stress. A dual innervation pathway for eccrine glands (adrenergic and cholinergic) may augment increased sweat output, but this remains to be substantiated. Circulating catecholamines appear not to mediate eccrine gland activity, but may play a role in the activation of apocrine sweat glands. Apocrine sweating is strongly regulated by psychological stimuli and localised to those body sites hosting apocrine glands, with adrenergic peripheral pathways being the primary effector. Accordingly, in the axilla psychological sweating leads to increased sweat output and malodour formation, although this form of sweating at this body site is not observed until puberty.
