From classic motor imagery to complex movement intention decoding: the noninvasive Graz-BCI approach

GR Müller-Putz, A Schwarz, J Pereira, P Ofner - Progress in brain research, 2016 - Elsevier
In this chapter, we give an overview of the Graz-BCI research, from the classic motor
imagery detection to complex movement intentions decoding. We start by describing the …

[HTML][HTML] Attempted arm and hand movements can be decoded from low-frequency EEG from persons with spinal cord injury

P Ofner, A Schwarz, J Pereira, D Wyss, R Wildburger… - Scientific reports, 2019 - nature.com
We show that persons with spinal cord injury (SCI) retain decodable neural correlates of
attempted arm and hand movements. We investigated hand open, palmar grasp, lateral …
