Brain-Computer Interfaces (BCIs) are communication systems, which enable users to send commands to computers by using brain activity only; this activity being generally measured by Electroencephalography (EEG). BCIs are generally designed according to a pattern recognition approach, i.e., by extracting features from EEG signals, and by using a classifier to identify the user’s mental state from...
امروزه گروه¬های تحقیقاتی مختلفی جهت کمک به افراد مبتلا به بیماری¬هایی نظیر ms، als و...، در زمینهbrain-computer interface (bci) فعالیت می¬کنند. رابط¬های مغز کامپیوتر (bci) کاربران را قادر می¬سازند بدون دخالت عضلات و اعصاب جانبی به برقراری ارتباط بپردازند و از آنجا که این رابط¬ها به کنترل عصبی¬عضلانی وابسته نیستند، به افرادی با بیماری¬های نابود¬کننده کنترل عصبی¬عضلانی (مانند اسکلروز جانبی آمیوتر...
OBJECTIVE Brain-computer interface technology has been applied to stroke patients to improve their motor function. Event-related desynchronization during motor imagery, which is used as a brain-computer interface trigger, is sometimes difficult to detect in stroke patients. Anodal transcranial direct current stimulation (tDCS) is known to increase event-related desynchronization. This study inv...
background & aim: traumatic brain injury is one of the main causes of death and disability. the aim of this study is to systematically review the articles which assessed some serum factors of traumatic brain injury patients in relation to their outcomes. methods & materials/patients: databases were searched for relevant publications from 2005 to 2014. selection criteria were:studies which evalu...

Introduction: Brain Computer Interface (BCI) systems based on Movement Imagination (MI) are widely used in recent decades. Separate feature extraction methods are employed in the MI data sets and classified in Virtual Reality (VR) environments for real-time applications. Methods: This study applied wide variety of features on the recorded data using Linear Discriminant Analysis (LDA) classifie...
Brain-computer interfaces (BCI) record brain signals, analyze and translate them into control commands which are relayed to output devices that carry out desired actions. These systems do not use normal neuromuscular output pathways. Actually, the principal goal of BCI systems is to provide better life style for physically-challenged people which are suffered from cerebral palsy, amyotrophic l...
