“…Skin conductance responses are observed not only in humans but also in other mammals with eccrine glands on the palm or sole, including rats (Lykken, 1962;Stevens and Landis, 1987), cats (Lang et al, 1964) and non-human primates (Bagshaw and Coppock, 1968;Laine et al, 2009). Across species, amygdala projects to the sudomotor system via hypothalamus and brainstem (Boucsein, 2012).…”

“…Stimulation of basolateral amygdala in lightly anesthetized cats generated skin conductance responses (Lang et al, 1964). During threat conditioning, selective bilateral amygdala lesions in rhesus monkeys have been shown to attenuate skin conductance responses evoked by CS+ (Bagshaw and Coppock, 1968;Pribram et al, 1979).…”

Threat conditioning is a laboratory model of associative learning across species that is often used in research on the etiology and treatment of anxiety disorders. At least 10 different conditioned responses (CR) for quantifying learning in human threat conditioning are found in the literature. In this narrative review, we discuss these CR by considering the following questions: (1) Are the CR indicators of amygdala-dependent threat learning? ( 2) To what components of formal learning models do the CR relate? (3) How well can threat learning be inferred from the CR? Despite a vast literature, these questions can only be answered for some CR. Among the CR considered, heart period, startle eye-blink and Pavlovian-to-instrumental transfer are most clearly related to amygdala-dependent threat learning. Formal learning models have mostly been studied for skin conductance responses, which are likely to reflect threat prediction and its uncertainty. Startle eyeblink and pupil size appear to best differentiate CS+/CS−, although few direct comparisons between CR exist. We suggest future directions for improving the quantification of threat conditioning.

“…Finally, it would be important to couple thermal observations to brain regions, fulfilling a bidirectional union between the brain and the visceral organs (Kuraoka & Nakamura, 2011). Stimulation of the central nucleus (Bagshaw & Coppock, 1968;Laine et al, 2009) as well as the corticomedial nucleus (Potegal, Hebert, DeCoster, & Meyerhoff, 1996) of the amygdala provide good cortical candidates for observing thermal changes associated with negative emotional states. Electroencephalography can also be integrated with thermal imaging since it does not occlude the participant's face, thus allowing the associations of subcortical emotion-related regions with the thermal print.…”

Thermal infrared imaging in psychophysiology: Potentialities and limits

2014

Functional infrared thermal imaging (fITI) is considered an upcoming, promising methodology in the emotional arena. Driven by sympathetic nerves, observations of affective nature derive from muscular activity subcutaneous blood flow as well as perspiration patterns in specific body parts. A review of 23 experimental procedures that employed fITI for investigations of affective nature is provided, along with the adopted experimental protocol and the thermal changes that took place on selected regions of interest in human and nonhuman subjects. Discussion is provided regarding the selection of an appropriate baseline, the autonomic nature of the thermal print, the experimental setup, methodological issues, limitations, and considerations, as well as future directions.

“…Schwartzbaum & Pribram (1961) had found that, under certain conditions, removal of the amygdaloid complex produced a disturbance in the habituation of motor activity. Later experiments Bagshaw & Menzies, 1968;Bagshaw & Coppock, 1968; found that the same operation markedly prolonged the habituation of the behavioral and some electroneural components of orienting and completely wiped out the viscero-autonomic arousal indicators, i.e., GSR, changes in heart and respiratory rate, etc., despite the fact that the organism's response mechanisms per se remained unimpaired. "Putting the results together, one could conclude that the GSR component of orienting is in some way crucial to subsequent behavioral habituation [learning, storage].…”

Recent work in neurophysiology has begun to close the paradigmatic gap between neurophysiology and the psychology of embodied behavior and movement. The present paper surveys these developments, traces the origins of the split between neurophysiology and neuropsychology and suggests that recent work by Pribram may provide a link between the psychology of consciousness, the neurophysiology of movement, and the growing body of work on nonverbal communication.
