Performance Differences Using a Vibro-Tactile P300 BCI in LIS-Patients Diagnosed With Stroke and ALS

Effects of a Vibro-Tactile P300 Based Brain-Computer Interface on the Coma Recovery Scale-Revised in Patients With Disorders of Consciousness
2020
Persons diagnosed with disorders of consciousness (DOC) typically suffer from motor and cognitive disabilities. Recent research has shown that non-invasive brain-computer interface (BCI) technology could help assess these patients’ cognitive functions and command following abilities. 20 DOC patients participated in the study and performed 10 vibro-tactile P300 BCI sessions over 10 days with 8–12 runs each day. Vibrotactile tactors were placed on the each patient’s left and right wrists and one foot. Patients were instructed, via earbuds, to concentrate and silently count vibrotactile pulses on either their left or right wrist that presented a target stimulus and to ignore …
Somatosensory Illusions Elicited by Sham Electromagnetic Field Exposure: Experimental Evidence for a Predictive Processing Account of Somatic Symptom…
2020
OBJECTIVE According to the predictive processing theory of somatic symptom generation, body sensations are determined by somatosensory input and central nervous predictions about this input. We examined how expectations shape predictions and consequently bodily perceptions in a task eliciting illusory sensations as laboratory analogue of medically unexplained symptoms. METHODS Using the framework of signal detection theory, the influence of sham Wi-Fi on response bias (c) and somatosensory sensitivity (d') for tactile stimuli was examined using the somatic signal detection task (SSDT). A healthy student sample (n = 83) completed the SSDT twice (sham Wi-Fi on/off) in a randomized order after…
Commentary: Preliminary Evidence for Training-Induced Changes of Morphology and Phantom Limb Pain
2019
The aim of this study was to investigate whether a special prosthetic training in phantom limb pain patients aimed at increasing the functional use of the prosthesis leads to neural morphological plasticity of brain structures and a reduction in phantom limb pain. For chronic pain disorders, it was shown that morphological alterations due to pain might become at least partially reversed by pain therapies. Phantom limb pain is a chronic pain disorder that is frequently followed by neural plasticity of anatomical brain structures. In our study, 10 patients with amputation of the upper limb participated in a two-week training with a myoelectric prosthesis with somatosensory feedback. Grip stre…
Spatial Cognition 2020/1: Book of abstracts : August 2-4, 2021, University of Latvia
2021
Spatial Cognition is concerned with the acquisition, development, representation, organization, and use of knowledge about spatial objects in real, virtual or hybrid environments and processed by human or artificial agents. Spatial Cognition includes research from different fields insofar as they are concerned with cognitive agents and space, such as cognitive and developmental psychology, linguistics, computer science, geography, cartography, philosophy, neuroscience, and education. Research issues in the field range from the investigation of human spatial cognition to mobile robot navigation, including topics such as wayfinding, spatial planning, spatial learning, internal and external re…

Suomessa vieraan kielen opiskelu aloitetaan tavallisimmin kolmannella luokalla, ja suurimmalle osalle oppilaista tämä kieli on englanti. Tällöin oppilas alkaa rakentaa kuvaa sekä englannin kielestä että itsestään englannin kielen opiskelijana. Onnistumisen kokemukset ovat tässä vaiheessa tärkeitä, ja yksi tapa niiden mahdollistamiseen on oppilaan oppimistyyliä vastaava opetus. Kolmannen luokan englannin oppitunneille osallistuu kuitenkin heterogeeninen ryhmä erilaisia oppijoita, minkä vuoksi on käytettävä vaihtelevia opetusmenetelmiä. Tässä tutkimuksessa keskityttiin seuraaviin oppimistyyleihin: visuaalinen, auditiivinen, kinesteettinen, taktiilinen sekä ryhmässä ja yksin oppiminen. Näistä …
Rappresentazioni tattili
2020
Sebbene molto spesso le persone con disabilità debbano accontentarsi di vivere parzialmente alcune esperienze, da diversi anni è aumentata l’attenzione dei siti museali verso la realizzazione di progetti e percorsi dedicati che consentano una fruizione tattile di opere e manufatti ai disabili visivi. Il contributo presenta due casi studio, che utilizzano modelli 3D per installazioni tattili. In presenza di deficit visivo, è importante rafforzare le facoltà percettive connettendo il tatto con i sensi residui e fornendo stimoli cognitivi diversi e paralleli. L’approccio multisensoriale, tattile e uditivo, realizzato grazie alla commistione tra modelli 3D e componenti elettroniche, favorisce l…
