Discriminating imagined and non-imagined tasks in the motor cortex area: entropy-complexity plane with a wavelet decomposition
(Elsevier Science, 2018-12)
Electroencephalograms reflect the electrical activity of the brain, which can be considered ruled by a chaotic nonlinear dynamics. We consider human electroencephalogram recordings during different motor type activities, ...
Estudo sobre interfaces cérebro-máquina e Interação humano-robô
(Universidade Federal de Minas GeraisUFMG, 2013-05-24)
Brain-machine interfaces (BMIs) are systems capable of extracting information from the brain activity of a user to allow the control of any device. The development of BMIs is a goal pursued by various research laboratories ...
Causal Shannon-Fisher characterization of motor/imagery movements in EEG
(Molecular Diversity Preservation International, 2018-09)
The electroencephalogram (EEG) is an electrophysiological monitoring method that allows us to glimpse the electrical activity of the brain. Neural oscillations patterns are perhaps the best salient feature of EEG as they ...
Detecção do potencial relacionado à imaginação do movimento usando a filtragem de Kalman
(Universidade Federal de Minas GeraisUFMG, 2012-12-07)
The brain-machine interface (BMI) is a communication system that uses brain signals to control the activation of external devices. The BMI is a two way interaction between people who have some motor impairment and the ...
Implicit motor imagery performance and cortical activity throughout the menstrual cycle
(Springer Science and Business Media LLC, 2023)
Low-Cost Robotic Guide Based on a Motor Imagery Brain-Computer Interface for Arm Assisted Rehabilitation
Motor imagery has been suggested as an efficient alternative to improve the rehabilitation process of affected limbs. In this study, a low-cost robotic guide is implemented so that linear position can be controlled via the ...
Prática mental na tarefa de alimentação para o tratamento de pessoas com doença de parkinson
(Universidade Federal de PernambucoUFPEBrasilPrograma de Pos Graduacao em Neuropsiquiatria e Ciencia do Comportamento, 2016)
Rhythmic activities of the brain: quantifying the high complexity of beta and gamma oscillations during visuomotor tasks
(American Institute of Physics, 2018-07)
Electroencephalography (EEG) signals depict the electrical activity that take place at the surface of the brain, and provide an important tool for understanding a variety of cognitive processes. The EEG are the product of ...
