چکیده

The Thought-Translation-Device (TTD) is a Brain-ComputerInterface (BCI) that enables completely paralyzed patients to communicate by the use of their brain signals only. Selfregulation of brain signals (e.g. the slow cortical potentials) is achieved by a feedback training. Visual impairment of these patients asks for an auditory feedback mode. The TTD can be entirely operated by combined listening and mental activity. It provides auditory feedback of brain signals which can operate a verbal spelling interface. The extension POSER allows for sonified orchestral real-time feedback of multiple EEG parameters for the training of self-regulation. The properties of the system are reported and the results of some studies and experiments with auditory feedback are presented.

A review on EEG based brain computer interface systems feature extraction methods

The brain – computer interface (BCI) provides a communicational channel between human and machine. Most of these systems are based on brain activities. Brain Computer-Interfacing is a methodology that provides a way for communication with the outside environment using the brain thoughts. The success of this methodology depends on the selection of methods to process the brain signals in each pha...

Brain Functional Connectivity Changes During Learning of Time Discrimination

The human brain is a complex system consist of connected nerve cells that adapts with and learn from the environment by changing its regional activities. Synchrony between these regional activities called functional network changes during the life, and with learning of new skills. Time perception and interval discrimination are among the most necessary skills for the human being to perceive mot...

Applying Genetic Algorithm to EEG Signals for Feature Reduction in Mental Task Classification

Brain-Computer interface systems are a new mode of communication which provides a new path between brain and its surrounding by processing EEG signals measured in different mental states.  Therefore, choosing suitable features is demanded for a good BCI communication. In this regard, one of the points to be considered is feature vector dimensionality. We present a method of feature reduction us...

Computer-Aided Tinnitus Detection based on Brain Network Analysis of EEG Functional Connectivity

Background: Tinnitus known as a central nervous system disorder is correlated with specific oscillatory activities within auditory and non-auditory brain areas. Several studies in the past few years have revealed that in the most tinnitus cases, the response pattern of neurons in auditory system is changed due to auditory deafferentation, which leads to variation and disruption of the brain net...
