How does an electroencephalogram work? An electroencephalogram (EEG) isa test that detects electrical activity in your brain using small, metal discs (electrodes) attached to your scalp. Your brain cells communicate via electrical impulses and are active all the time, even when you're asleep. This...
In this study we look into how a number of participants navigate in an urban environment; between specific identified buildings in the city. The brain activity of the participants is recorded with a portable EEG device, while simultaneously video recording the route. Through this experiment we aim...

For example, in neuromarketing, combining eye tracking, facial expressions, and GSR can reveal: What caught the viewer’s attention? How did they emotionally react? Was the reaction positive, negative, or neutral? This multimodal approach makes biometric research an invaluable tool for understanding ...
In other words: While ECG/PPG are ideal measures to track emotional arousal, they are not able to reveal emotional valence, the direction of an emotion. The true power of ECG/PPG techniques unfolds as these sensors are combined with other data sources such asfacial expression analysis,EEG, an...
(EEG) to monitor the response, a team of neuroscientists led by Giulio Tononi and Marcello Massimini found thatthe electrical echo generated by the energy pulse will bounce all around a conscious brain, but stays very localised in an unconscious brain. In other words, the conscious brain is ...
Even the permanent loss of the capacity of dreaming does not mean being disabled. Peretz Lavie, a researcher from Israel, has been observing a patient Yuval Chamtzani. He got an injury at 19 by a piece of shrapnel penetrating his brain, and consequently, Chamtzani lost REM sleep and ...
Which of the following gives both a three-dimensional structural view of the brain as well as making brain activity visible? a. CT scan b. MRI scan c. EEG d. fMRI What artery supplies the parietal lobe with blood? What does the posterior parietal lobe control?
). If the internal states of a sophisticated distributional model reveal a pattern that is consistent across all words that are synonyms of another word, then we could say that this modelstatistically approachesthe concept “synonymy.” Nevertheless, this representation does not exist if we do not...
The signal was amplified using a Nihon Kohden system (EEG-4421G), with band limits between 0.1 and 70 Hz (24 dB/octave) and an additional notch filter at 50 Hz. Data was digitized at a 500 Hz sampling rate and analyzed off-line. The EOG was registered from medial upper and lateral ...
