Brain-State Dependent Stimulation boosts functional recovery following stroke
Mrachacz-Kersting, Natalie; Stevenson, Andrew James Thomas; Jørgensen, Helle R. M.; Severinsen, Kåre Eg; Aliakbaryhosseinabadi, Susan; Jiang, Ning; Farina, Dario (Wiley, 2018-11-08)Objective Adjuvant protocols devised to enhance motor recovery in subacute stroke patients have failed to show benefits with respect to classic therapeutic interventions. Here we evaluate the efficacy of a novel brain-state ... -
Decoding covert somatosensory attention by a BCI system calibrated with tactile sensation
Yao, Lin; Sheng, Xinjun; Mrachacz-Kersting, Natalie; Zhu, Xiangyang; Farina, Dario; Jiang, Ning (Institute of Electrical and Electronics Engineers, 2017-10-12)Objective: We propose a novel calibration strategy to facilitate the decoding of covert somatosensory attention by exploring the oscillatory dynamics induced by tactile sensation. Methods: It was hypothesized that the ... -
The effect of type of afferent feedback timed with motor imagery on the induction of cortical plasticity
Mrachacz-Kersting, Natalie; Voigt, Michael; Stevenson, Andrew James Thomas; Aliakbaryhosseinabadi, Susan; Jiang, Ning; Dremstrup, Kim; Farina, Dario (Elsevier, 2017-11-01)A peripherally generated afferent volley that arrives at the peak negative (PN) phase during the movement related cortical potential (MRCP) induces significant plasticity at the cortical level in healthy individuals and ... -
Factors of Influence on the Performance of a Short-Latency Non-Invasive Brain Switch: Evidence in Healthy Individuals and Implication for Motor Function Rehabilitation
Xu, Ren; Jiang, Ning; Mrachacz-Kersting, Natalie; Dremstrup, Kim; Farina, Dario (Frontiers Media, 2016-01-21)Brain computer interfacing (BCI) has recently been applied as a rehabilitation approach for patients with motor disorders, such as stroke. In these closed-loop applications, a brain switch detects the motor intention from ... -
Influence of dual-tasking with different levels of attention diversion on characteristics of the movement-related cortical potential
Aliakbaryhosseinabadi, Susan; Kamavuako, Ernest Nlandu; Jiang, Ning; Farina, Dario; Mrachacz-Kersting, Natalie (Elsevier, 2017-11-01)Dual tasking is defined as performing two tasks concurrently and has been shown to have a significant effect on attention directed to the performance of the main task. In this study, an attention diversion task with two ... -
Movement-related cortical potentials in paraplegic patients: abnormal patterns and considerations for BCI-rehabilitation
Jiang, Ning; Xu, Ren; Vuckovic, Aleksandra; Hasan, Muhammad; Mrachacz-Kersting, Natalie; Allan, David; Fraser, Matthew; Nasseroleslami, Bahman; Conway, Bernie; Dremstrup, Kim; Farina, Dario (Frontiers, 2014-08-27)Non-invasive EEG-based Brain-Computer Interfaces (BCI) can be promising for the motor neuro-rehabilitation of paraplegic patients. However, this shall require detailed knowledge of the abnormalities in the EEG signatures ... -
A Multi-class BCI based on Somatosensory Imagery
Yao, Lin; Mrachacz-Kersting, Natalie; Sheng, Xinjun; Zhu, Xiangyang; Farina, Dario; Jiang, Ning (Institute of Electrical and Electronics Engineers, 2018-06-18)In this study, we investigated the performance of a multi-class brain-computer interface (BCI). The BCI system is based on the concept of somatosensory attentional orientation (SAO), in which the user shifts and maintains ... -
A multi-class tactile brain-computer interface based on stimulus-induced oscillatory dynamics
Yao, Lin; Chen, Mei Lin; Sheng, Xinjun; Mrachacz-Kersting, Natalie; Zhu, Xiangyang; Farina, Dario; Jiang, Ning (Elsevier, 2017-07-24)We proposed a multi-class tactile brain-computer interface that utilizes stimulus-induced oscillatory dynamics. It was hypothesized that somatosensory attention can modulate tactile induced oscillation changes, which can ... -
Performance of Brain-Computer Interfacing Based on Tactile Selective Sensation and Motor Imagery
Yao, Lin; Sheng, Xinjun; Mrachacz-Kersting, Natalie; Zhu, Xiangyang; Farina, Dario; Jiang, Ning (Institute of Electrical and Electronics Engineers, 2017-11-03)A large proportion of users do not achieve adequate control using current non-invasive Brain-computer Interfaces (BCI). This issue has being coined “BCI-Illiteracy”, and is observed among BCI modalities. Here, we compare ...
