Progress in Brain Computer Interface: Challenges and Opportunities

Abstract

Brain computer interfaces (BCI) provide a direct communication link between the brain and a computer or other external devices. They offer an extended degree of freedom either by strengthening or by substituting human peripheral working capacity and have potential applications in various fields such as rehabilitation, affective computing, robotics, gaming, and neuroscience. Significant research efforts on a global scale have delivered common platforms for technology standardization and help tackle highly complex and non-linear brain dynamics and related feature extraction and classification challenges. Time-variant psycho-neurophysiological fluctuations and their impact on brain signals impose another challenge for BCI researchers to transform the technology from laboratory experiments to plug-and-play daily life. This review summarizes state-of-the-art progress in the BCI field over the last decades and highlights critical challenges.

Influence of Implantation Depth on the Performance of Intracortical Probe Recording Sites

“…Intracortical microelectrode arrays (MEAs) are capable of recording the electrical activity of neurons within the cortex with high temporal and spatial resolution for single unit activity (SUA) [1], thus enabling a variety of brain-machine interface applications [2][3][4][5][6][7]. Advances in micro-scale manufacturing have enabled a wide design space for these devices relative to materials, size, and complexity [8][9][10][11].…”

Advanced Bioelectrical Signal Processing Methods: Past, Present and Future Approach—Part II: Brain Signals

“…The auditory EP (AEP) is investigated with short-time sounds (100 s) with different frequencies, so-called clicks using headphones in only one ear or both ears at the same time. The AEP stimuli are repeated 2000 times with the frequency of 1–50 Hz [ 183 , 184 , 185 ].…”

Brain-Computer Interfaces Systems for Upper and Lower Limb Rehabilitation: A Systematic Review

“…In fact, it is becoming an innovative neurological technology that successfully allows the restoration and improvement of people’s motor and communication abilities [ 5 , 6 ]. According to [ 7 , 8 , 9 , 10 , 11 , 12 ], its application fields can be divided into communication and control, medical applications, training and education, games and entertainment, monitoring, prevention, detection and diagnosis, intelligent environments, neuromarketing, advertising, security, and authentication. However, this review focuses specifically on examining the applications proposed exclusively as support in rehabilitation processes of the upper and lower limbs of the human body.…”
