IntroductionIn experimental psychophysiology, human motor reactivity to sensory stimulation is usually indexed by surface electromyography (EMG), which requires the placement of several electrodes on the skin surface [1]. This limits the mobility of the subject and reduces the possible contexts in which motor responses can be recorded and evaluated. In * Corresponding author. addition, EMG captures only the activity of specific muscle groups, whereas certain motor reflexes to sensory stimuli, such as the startle reflex, involve a global motor response characterized by complex muscle contraction patterns at different body areas [2]. A detailed investigation of these global motor reactivity patterns, in relation to underlying physiological control mechanisms, could result in a more systematic mapping of psychophysiological processes under sensory stimulation.0169-2607/$ -see front matter

Home self-training: Visual feedback for assisting physical activity for stroke survivors

“…For instance, Lin et al [12] employed a double CCD camera to capture the motion during rehabilitation sessions. In [13], the authors made use of a stereo-vision system in order to detect and assess the human motor reactivity under stimulation. On the other hand, some works have reinforced visionbased methods by combining markerless acquisition systems with other kinds of sensors or technologies.…”

Quantifying the Acoustic Startle Response in Mice Using Standard Digital Video

“…High-speed video has been used to capture the startle response in various species of fish (Wieland and Eaton, 1983;Hale, 2000;Rice et al, 2011;Chicoli et al, 2014;Hale et al, 2016). High-speed video (Derakhshani and Lovelace, 2010;Bernard et al, 2013) and standard video (Essex et al, 2003;Vousdoukas et al, 2012;Cosić et al, 2016) have also been used in the automated analysis of eye blinks in response to startling stimuli in humans. High-speed video has also been FIGURE 4 | Prepulse inhibition (PPI).…”
