1 Interpreting Event-Related Brain Potentials
Our ability to feel, think, and act can in some way be attributed to the workings of the brain. For over a century, scientists have used measures of brain activity to gain insights into perceptual, cognitive, and motor functions. As a result, researchers have developed a variety of methods to measure brain activity noninvasively (e.g., Rugg, 1999). These methods roughly fall into two classes: '...
متن کاملSymbolic dynamics of event-related brain potentials.
We apply symbolic dynamics techniques such as word statistics and measures of complexity to nonstationary and noisy multivariate time series of electroencephalograms (EEG) in order to estimate event-related brain potentials (ERP). Their significance against surrogate data as well as between different experimental conditions is tested. These methods are validated by simulations using stochastic ...
متن کاملLearning effects on event-related brain potentials.
This study investigates whether learning can manifest itself in EEG changes without explicit awareness of the acquired knowledge and without any motor requirement (to rule out acquisition of motor skills). Subjects passively heard particular stimulus combinations interspersed with random combinations. Immediately after this, stimulus combinations were presented which contained violations of the...
متن کاملEvent-related brain potentials and human language.
The human capacity to produce and comprehend language is one of the most distinctive characteristics of our species. However, understanding the cognitive and neural underpinnings of human language has proved difficult, in part because these processes are rapid, complex and (for the most part) inaccessible to conscious reflection. Methodologies are needed that provide continuous measurement duri...
متن کاملEvent-Related Brain Potentials for Goal-Related Power Grips
Recent research has shown that neurophysiological activation during action planning depends on the orientation to initial or final action goals for precision grips. However, the neural signature for a distinct class of grasping, power grips, is still unknown. The aim of the present study was to differentiate between cerebral activity, by means of event-related potentials (ERPs), and its tempora...
