“…The rationale behind using a tap on the patellar tendon is to activate the specific set of CNS regions (premotor-basal ganglia; EDA-2 pathways) responsible from evoked EDA (Boucsein, 1992;Esen et al, 1997;Weitkunat et al, 1990). Thus, any change in the parameters of EDA due to CPEMFs application may be related to its effect on the evoked CNS activity.…”

“…Mechanical stimulus in the form of a "tap" on the patellar tendon is a proprioceptive stimulus producing impulses that ascend in the spinal cord. These impulses conduct to the thalamus and then to the somatosensory cortex, culminating in the activation of premotor cortex (Weitkunat et al, 1990). As a result, the EDA-2 system (Boucsein, 1992), which includes premotor cortex and the basal ganglia, is activated.…”

“…Therefore, there is particular concern about the possible effects on the brain because mobile phones are conventionally held close to the head. With regard to possible influences on the brain, the authors concentrated primarily on change in EDA that are controlled by premotor area of contralateral cortex and the basal ganglia (Boucsein, 1992;Esen et al, 1997;Esen & Esen 2002;Weitkunat et al, 1990).…”

Effect of Electromagnetic Fields Emitted by Cellular Phones on the Latency of Evoked Electrodermal Activity

The widespread use of cellular phones raises the question of their possible adverse biological effects, especially on the central nervous system (CNS). Therefore, the authors examined the effect of electromagnetic fields emitted by cellular phones (CPEMFs) on the evoked neuronal activity of CNS relating to generation and representation of electrodermal activity (EDA), an index of sympathetic nervous system activity. EDA (skin resistance response; SRR) latency was lengthened approximately 200 ms with CPEMFs exposure irrespective of the head site next to mobile phone used. Hemispheric asymmetry of EDA-2 pathway, which is represented by shorter SRR latency in the right hand of the right hand responders, was also distorted with CPEMFs. Because the CNS regions including EDA-2 are also involved in tasks of motor timing and time estimation, delayed response in this neuronal network due to CPEMFs exposure may increase the response time of mobile phone users. Therefore, the findings point to the potential risks of mobile phones on the function of CNS and consequently, possible increase in the risk of phone-related driving hazards.

“…A similar strategy can be used to identify the neural substrates of the behavioral phenotype. Considerable evidence indicates that the specific EDR to psychologically significant stimuli is associated with activity in a distributed neural network involving regions of prefrontal cortex, anterior cingulate and right inferior parietal cortex (Patterson et al 2002;Tranel and Damasio 1994;Williams et al 2000), and it is likely that nonspecific EDR activity arises from similar brain regions (Critchley 2002;Weitkunat et al 1990). By extension, EDR lability-stability may be determined by the degree of activation of this neural network.…”

Electrodermal response (EDR) lability is a psychophysiological trait reflecting stable individual differences in electrodermal activation as indexed by frequency measures of phasic EDR activity. There is no consistent evidence that EDR lability reflects dispositional or clinical anxiety. However, EDR lability appears to be related to individual differences in the overt expression of emotional and antagonistic impulses. Greater EDR lability is associated with a relatively undemonstrative and agreeable disposition, whereas greater EDR stability is associated with a relatively expressive and antagonistic disposition. The inverse relationship between EDR lability and the expression of emotional and antagonistic impulses suggests that EDR lability may reflect individual differences in the effortful control of such expression. This hypothesis is consistent with cognitive effort interpretations of phasic EDR activity, with evidence of the sensitivity of phasic EDR activity to capacity-demanding tasks, and with evidence of reduced spare capacity among EDR labile individuals under cognitive challenge. Individual differences in effortful self-control may explain the association of greater EDR lability with essential hypertension and greater EDR stability with forms of antisocial behavior.

“…Probably such differences may originate both at spinal and supraspinal levels." In the palmar sweat glands activation, structures of all the levels of the central nervous system are involved (Ladpli & Wang 1960, Isamat 1961, Wilcott 1969, Wilcott & Bradley 1970, Venables & Christie 1973, Edelberg 1973, Delerm et al 1982, Fowles 1986, Sato et al 1989, Weitkunat et al 1990, Venables 1991, Turkstra 1995. Probably, highest centres control the palmar sweat glands activation unless otherwise prevented (Venables 1991) and the whole expression of the function is more complicate than the simple scheme of the general sympathetic arousal view implies.…”

We tested the hypothesis that palmar sweat glands activation is expressed every time a mass sympathetic activation takes place. We performed (i) eleven palmar electrodermal recordings during sexual intercourse and orgasm of one male and one female student, (ii) 4 palmar electrodermal recordings plus heart rate during sexual intercourse and orgasm of the same couple, and (iii) 3 plantar electrodermal recordings during masturbation and ejaculation of 3 male students. High palmar electodermal activity was recorded during sexual intercourse but small during orgasm. The higher value of heart rate was recorded at the moment of orgasm. Sizeable plantar electodermal response was recorded during ejaculation after masturbation. We concluded that the palmar sweat glands activation cannot be considered as an indiscriminate following of sympathetic discharge.
