Influence of transcranial direct current stimulation of the dorsolateral prefrontal cortex on pain related emotions: A study using electroencephalographic power spectrum analysis

Effects of Listening to Music versus Environmental Sounds in Passive and Active Situations on Levels of Pain and Fatigue in Fibromyalgia

“…Music and environmental sounds exhibit the same therapeutic effect on pain in our study, despite not sharing similar physiological, cognitive, and emotional effects. Outside a common distractive mechanism, this absence of difference between two basically different auditory stimuli may be linked to the fact that complaints of pain and fatigue in patients with FM are mostly related to a cognitive interpretation of sensory information, involving primarily the frontal cortex and not the limbic system (Maeoka, Matsuo, Hiyamizu, Morioka, & Ando, 2012;Sogabe, Yagasaki, Onozawa, & Kawakami, 2013). This hypothesis is in accordance with findings on the effects of cognitive behavioral therapy (CBT) and psychoeducational intervention in FM (Kwekkeboom, Cherwin, Lee, & Wanta, 2010;Luciano et al, 2013).…”

The Uncertain Outcome of Prefrontal tDCS

“…Was shown to decrease : a) working memory performance [36]; b) risk taking behaviors [37]; c) negative emotions perception [38-39]; d) categorization learning [28]); e) executive functioning performance only in a COMT Met-Met group (cognitive flexibility [40]). Was shown to increase : a) working memory performance [21,41-49]; b) positive emotion processing [50-52]; c) pain thresholds [53] ; d) performance on verbal tasks (verbal; word retrieval:[54]; word fluency:[18]); e) executive function performance (mental flexibility: [22]; inhibition: [46]; problem solving: [24,55-56]; planning [15]); f) control of negative emotions [39,57]; g) memory performance and learning [25,27,58-60]. Showed no significant effect on: a) mood [61].…”

Cranial electrotherapy stimulation and transcranial pulsed current stimulation: A computer based high-resolution modeling study

“…CES led to changes in alpha and beta frequency ranges suggesting potential neuroplastic and cognitive effects of this technique. Interestingly, similar changes in alpha and beta bands were shown to be associated with a reduction in the emotional-cognitive aspects of pain in a study using transcranial direct current stimulation, which is another type of non-invasive brain stimulation (Maeoka et al, 2012). Though these results are promising, additional studies must be done due to the lack of mechanistic studies, particularly in CES (Edelmuth et al, 2010).…”
