On scratching your own itch
Following Massimo Banzi’s comment that the Arduino development board might be seen as a means of ‘scratching your own itch’, this paper explores the concept of affect in relation to physical computing, and investigates the ways in which cybernetic and networked objects could be said to enact a series of process-philosophical and object-oriented tensions. In so doing it addresses the cultural sa...
متن کاملInduction of nocebo and placebo effects on itch and pain by verbal suggestions.
Physical complaints, such as pain, can be effectively reduced by placebo effects through induction of positive expectations, or increased by nocebo effects through induction of negative expectations. In the present study, verbally induced nocebo and placebo effects on itch were experimentally investigated for the first time. In part 1, the role of verbal suggestions in inducing nocebo effects o...
متن کاملRole of Conditioning and Verbal Suggestion in Placebo and Nocebo Effects on Itch
Placebo and nocebo effects are known to play a key role in treatment effects in a wide variety of conditions. These effects have frequently been investigated with regard to pain and also in other physical sensations, but have hardly been investigated with regard to itch. In addition, neither in pain nor in any other physical sensation, the single and combined contribution of the expectancy mech...
متن کاملThe imagined itch: brain circuitry supporting nocebo-induced itch in atopic dermatitis patients.
BACKGROUND Psychological factors are known to significantly modulate itch in patients suffering from chronic itch. Itch is also highly susceptible to both placebo and nocebo (negative placebo) effects. Brain activity likely supports nocebo-induced itch, but is currently unknown. METHODS We collected functional MRI (fMRI) data from atopic dermatitis (AD) patients, in a within-subject design, a...
متن کاملCerebral representation of the relief of itch by scratching.
Cerebral processing of itch-scratching cycles was studied with functional magnetic resonance imaging (fMRI) in healthy volunteers. The back of the hand was repetitively scratched in the absence and presence of itch induced by histamine applied close to the scratched site. Blood-oxygenation-level-dependent (BOLD) effects were assessed in predefined cortical and subcortical brain regions of inter...
