... It has been suggested by Wiesendanger (1986) that the SMA is involved in the planning and production of complex movements. A recent study by Uhl et al. (1993) revealed that SMA involvement is greater for bilateral movements in which movements of each hand are asymmetric as opposed to symmetric movements. These and other studies (for review, see Cunnington, et al., 1996) clearly indicate that the SMA operates bilaterally, with complex inter-hemispheric interactions modulating the activity of the left and right primary motor areas. ...

... In the near future, app-based EMA will also allow the isolation of neurophysiological correlates of having and/or expressing certain dispositions within certain situations. For example, mobile electroencephalography (EEG) caps (e.g., Eegosports) could be synced with an EMA app in order to record eventrelated potentials, or preparatory neural activities such as readiness-potentials (RPs); i.e., relative changes in the activity of the primary motor cortex and surrounding regions associated with preparedness to act (e.g., Freude and Ullsperger, 1987;Coles et al., 1988;Coles, 1989;Deecke et al., 1990;Shibasaki and Hallett, 2006;Ibanez et al., 2012;Nachev and Hacker, 2014). Through these means we might find that, when an individual has a certain disposition, certain preparatory activities occur under certain situations. ...

... postsynaptic potentials and related activity (Birbaumer et al., 1990;Caton, 1875;Ikeda et al., 1995;Kotchoubey et al., 1997;Lang et al., 1989;Niemann et al., 1992;Speckman & Caspers, 1979Caspers et al., 1980;Speckman et al., 1984;Caspers et al., 1987;Rockstroh 1993;Rockstroh et al., 1989). Indeed, topographic variations of slow potentials within human EEG have been examined during complex and sustained cognitive operations and used for functional localization (e.g., Lang et al., 1993;Rosler et al., 1997;see too Curry & Pleydell-Pearce, 1995;Pleydell-Pearce & Whitecross, 2000). ...

... Therefore, we decided to conduct our research aimed at introducing the community to the Braille method and its positive effects, measured using a special scale called the Hamilton Depression Scale. 4 This is done by restoring self-confidence, social interaction, and avoiding abnormal behaviors. This leads to overcoming the difficulties experienced by blind people in adapting to the society in which they live, developing their sense of belonging and effectiveness, and overcoming all the difficulties that prevent them from being in a state of dependence on others to become self-reliant. ...

... The fact that our blind and sighted participants performed well, and did so with only 3-s haptic explorations of the experimental stimulus objects, is consistent with the operation of the direct haptic apprehension model (Klatzky & Lederman, 1987; Lederman et al., 1990). As of the present date, many neurophysiological investigations have demonstrated cortical reorganization of function following the onset of blindness, where cortical areas normally responsible for vision become responsive to tactile and haptic input (e.g., Burton, Snyder, Conturo, Akbudak, Ollinger, & Raichle, 2002; L. G. Cohen et al., 1997; Hyvärinen, Carlson, & Hyvärinen, 1981; Lanzenberger et al., 2001; Pietrini et al., 2004; Ptito & Kupers, 2005; Sadato, Okada, Honda, & Yonekura, 2002; Sadato et al., 1996; Stilla, Hanna, Hu, Mariola, Deshpande, & Sathian, 2008; Uhl, Franzen, Lindinger, Lang, & Deecke, 1991; Wanet-Defalque et al., 1988; Weaver & Stevens, 2007). A number of similar neurophysiological studies have additionally found that more " visual areas " are recruited for tactile and haptic tasks in the late blind than in the congenitally blind (e.g., Büchel, Price, Frackowiak, & Friston, 1998; Goyal, Hansen, & Blakemore, 2006). ...

... As a secondary aim, we explored the potential contribution of frontostriatal networks in ecstasy-induced neurocognitive dysfunction. This was achieved by evaluating performance on memory tasks that recruit frontostriatal circuitry, including the encoding of material (Simons and Spiers, 2003) and proactive interference recall, which refers to the disruption of newly formed memories by previously encoded similar memories (García-Pacios et al., 2013;Jonides and Nee, 2006;Uhl et al., 1990). In addition, we examined a range of other components of executive functioning that are known to recruit frontostriatal networks, including working memory, planning, set-shifting and inhibition. ...

... The rationale of using US therapy in carpal tunnel syndrome is based on results of some studies which showed its beneficial effects such as an anti-inflammatory effect, stimulation of nerve regeneration via enhanced blood flow, and membrane permeability, as well as improvement of conduction properties in the nerve. Activation of these mechanisms by US treatment might (in assumption) facilitate recovery from nerve compression [27,28]. Results of study by Ebenbichler et al., (1998) showed that pulsed ultrasound at frequency of 1MHz, and energy of 1,0 W/cm 2 applied to the palmar side of the wrist over 15 min for ten consecutive days, followed by twice weekly treatments for five additional weeks resulted in cessation of pain and nocturnal paresthesiae, improved sensation in the fingers innervated by the median nerve, increased grip and pinch strength and improved electrophysiological parameters. ...

... One deeply investigated case of sensory loss is blindness, that is, the lack of visual input to the brain. Previous research has shown that cortical structures most strongly activated by visual input in sighted brains are activated by a plethora of other cognitive functions in visually deprived brains (Bedny, 2017), including braille reading (Büchel et al., 1998;Burton et al., 2012;Rączy et al., 2019;Reich et al., 2011;Sadato et al., 1998;Uhl et al., 1991;Sadato, 1996). However, overlapping functional responses alone cannot inform us about the nature of the observed activations, that is, what kind of information they represent and thus what role they play in cognitive processing. ...
