Abstract In a New Zealand population-based case-control study we assessed associations with occupational exposure to electric shocks, extremely low-frequency magnetic fields (ELF-MF) and motor neurone disease using job-exposure matrices to assess exposure. Participants were recruited between 2013 and 2016. Associations with ever/never, duration, and cumulative exposure were assessed using logistic regression adjusted for age, sex, ethnicity, socioeconomic status, education, smoking, alcohol consumption, sports, head or spine injury and solvents, and mutually adjusted for the other exposure. All analyses were repeated stratified by sex. An elevated risk was observed for having ever worked in a job with potential for electric shocks (odds ratio (OR)=1.35, 95% confidence interval (CI): 0.98, 1.86), with the strongest association for the highest level of exposure (OR=2.01, 95%CI: 1.31, 3.09). Analysis by duration suggested a non-linear association: risk was increased for both short-duration (<3 years) (OR= 4.69, 95%CI: 2.25, 9.77) and long-duration in a job with high level of electric shock exposure (>24 years; OR=1.88; 95%CI: 1.05, 3.36), with less pronounced associations for intermediate durations. No association with ELF-MF was found. Our findings provide support for an association between occupational exposure to electric shocks and motor neurone disease but did not show associations with exposure to work-related ELF-MF.

The study examined the effects of social intelligence on the Milgram (1963) paradigm. 24 male subjects were commanded by the experimenter to administer electric shocks (simulated to appear real) to a confederate. Social intelligence as measured significantly mediated the degree to which subjects were prepared to obey the experimenter's commands and inflict suffering on another. The finding was interpreted as suggesting that broader personality differences relating to obedience-disobedience and altruistic acts, such as alleviating the plight of a suffering victim, are more likely to be found in the realm of cognitive abilities than with traditional temperament traits.

AbstractSignificant others provide individuals with a sense of safety and security. However, the mechanisms that underlie attachment-induced safety are hardly understood. Recent research has shown beneficial effects when viewing pictures of the romantic partner, leading to reduced pain experience and defensive responding. Building upon this, we examined the inhibitory capacity of loved face pictures on fear learning in an instructed threat paradigm. Pictures of loved familiar or unknown individuals served as signals for either threat of electric shocks or safety, while a broad set of psychophysiological measures was recorded. We assumed that a long-term learning history of beneficial relations interferes with social threat learning. Nevertheless, results yielded a typical pattern of physiological defense activation towards threat cues, regardless of whether threat was signaled by an unknown or a loved face. These findings call into question the notion that pictures of loved individuals are shielded against becoming threat cues, with implications for attachment and trauma research.

Different Levels

The present study was concerned with the masking and pain-attenuating effect of vibration at different levels of intensity of noxious stimulation. Forty Ss were given noxious stimulation in the form of increasingly painful electric shocks in trials where such shocks were presented with and without concurrent vibratory stimulation. The masking or pain-attenuating effect of the vibration was greatest at the lowest level of noxious stimulus intensity and decreased as the noxious stimulation intensity increased. At the highest level of noxious stimulation the effect of vibration was not significant although there was a tendency for Ss with higher pain tolerance to show summation. The possible relevance of the intensity of the vibratory stimulus to this pattern of results was discussed.

Electric Shocks

The selection of reward-seeking and aversive behaviors is controlled by two distinct D1 and D2 receptor-expressing striatal medium spiny neurons, namely the direct pathway MSNs (dMSNs) and the indirect pathway MSNs (iMSNs), but the dynamic modulation of signaling cascades of dMSNs and iMSNs in behaving animals remains largely elusive. We developed an in vivo methodology to monitor Förster resonance energy transfer (FRET) of the activities of PKA and ERK in either dMSNs or iMSNs by microendoscopy in freely moving mice. PKA and ERK were coordinately but oppositely regulated between dMSNs and iMSNs by rewarding cocaine administration and aversive electric shocks. Notably, the activities of PKA and ERK rapidly shifted when male mice became active or indifferent toward female mice during mating behavior. Importantly, manipulation of PKA cascades by the Designer Receptor recapitulated active and indifferent mating behaviors, indicating a causal linkage of a dynamic activity shift of PKA and ERK between dMSNs and iMSNs in action selection.

1. Electrical pulses (amplitude -0.05 to -15 mV.; duration 20-120 msec.) have been recorded from the stolon of Cordylophora lacustris following stimulation. These pulses are propagated with an average velocity of 2.7 cm./sec. at 22° C. 2. Brief electric shocks of little more than threshold intensity can evoke bursts of pulses. The number of pulses in a burst increases with stimulus intensity, but the shape and size of individual pulses do not. 3. Repetitive stimulation causes facilitation of both size of single pulses and number of pulses in a burst. Refractory period, if present, is variable. The minimum interval between two pulses is about 200 msec. 4. Mechanical stimulation evokes pulses identical to those evoked by electrical stimulation. 5. The greater the number of pulses recorded in the stolon near a polyp, the greater and faster is the contraction of that polyp. 6. The number of pulses, but not their individual sizes, decreases with increasing distance from the point of stimulation. 7. It is concluded that conduction in the stolon and the electrical pulses are due to nervous activity and that the conducting system is a network having interneural junctions which sometimes require to be facilitated.

1. In Gonactinia well-developed ectodermal muscle and nerve-net extend over the column and crown and play an important part in the anemone's behaviour. 2. Common sequences of behaviour are described. Feeding is a series of reflex contractions of different muscles by means of which plankton is caught and swallowed. Walking, in the form of brief looping steps, differs markedly in that it continues after interruptions. Anemones also swim with rapid tentacle strokes after contact with certain nudibranch molluscs, strong mechanical disturbance or electrical stimulation. 3. Swimming is attributed to temporary excitation of a diffuse ectodermal pacemaker possibly situated in the upper column. 4. From the results of electrical and mechanical stimulation it is concluded that the endodermal neuromuscular system resembles that of other anemones but that the properties of the ectodermal neuromuscular system require a new explanation. The size and spread of responses to electric shocks vary with intensity, latency is variable and there is a tendency to after-discharge. There is precise radial localization, for example touching a tentacle or the column causes it to bend towards or away from the stimulus. 5. A model to explain these and other features includes multipolar nerve cells closely linked to the nerve-net which would act as intermediate motor units, causing local contraction of the ectodermal muscle. This scheme can be applied to other swimming anemones but there is no evidence that it holds for sea anemones generally.

The One

<p>Consider Lt. Commander Data from Star Trek: The Next Generation, the droid C3PO from Star Wars, or the Replicants that appear in Bladerunner: They can use language (or many languages), they are rational, they form relationships, they use language that suggests that they have a concept of self, and even language that suggests that they have “feelings” or emotional experience. In the films and TV shows that they appear, they are depicted as having frequent social interaction with human beings; but would we have any moral obligations to such a being if they really existed? What would we be permitted to do or not to do to them? On the one hand, a robot like Data has many of the attributes that we currently associate with a person. On the other hand, he has many of the attributes of the machines that we currently use as tools. He (and other science-fiction machines like him) closely resembles one of the things we value the most (a person), and at the same time, one of the things we value the least (an artefact), leading to an apparent ethical paradox. What is its solution?</p>
