Simultaneous Acquisition of EEG and NIRS during Cognitive Tasks for an Open Access Dataset

Shin, Jaeyoung ; Lühmann, Alexander von ; Kim, Do-won ; Mehnert, Jan ; Hwang, Han-Jeong ; Müller, Klaus-Robert (2017)

We provide an open access multimodal brain-imaging dataset of simultaneous electroencephalography (EEG) and near-infrared spectroscopy (NIRS) recordings. Twenty-six healthy participants performed three cognitive tasks: 1) n-back (0-, 2- and 3-back), 2) discrimination/selection response task (DSR) and 3) word generation (WG) tasks. The data provided includes: 1) measured data, 2) demographic dat...

Assessing the depth of cognitive processing as the basis for potential user-state adaptation

Nicolae, Irina-Emilia ; Acqualagna, Laura ; Blankertz, Benjamin (2017)

Objective: Decoding neurocognitive processes on a single-trial basis with Brain-Computer Interface (BCI) techniques can reveal the user's internal interpretation of the current situation. Such information can potentially be exploited to make devices and interfaces more user aware. In this line of research, we took a further step by studying neural correlates of different levels of cognitive pro...

Nicolae, Irina-Emilia ; Acqualagna, Laura ; Blankertz, Benjamin (2017)

EEG and behavioral data of seventeen participants recorded by members of the Neurotechnology Group at Technische Universität Berlin. Details of the study are published in "Nicolae I-E, Acqualagna L and Blankertz B. (2017). Assessing the Depth of Cognitive Processing as the Basis for Potential User-State Adaptation. Front. Neurosci. 11:548, 2017a. doi: https://doi.org/10.3389/fnins.2017.00548

Prediction of difficulty levels in video games from ongoing EEG

Neumann, Laura ; Schultze-Kraft, Matthias ; Dähne, Sven ; Blankertz, Benjamin (2017)

Real-time assessment of mental workload from EEG plays an important role in enhancing symbiotic interaction of human operators in immersive environments. In this study we thus aimed at predicting the difficulty level of a video game a person is playing at a particular moment from the ongoing EEG activity. Therefore, we made use of power modulations in the theta (4–7 Hz) and alpha (8–13 Hz) freq...

Maritime cognitive workload assessment

Miklody, Daniel ; Uitterhoeve, Wendie M. ; van Heel, Dimitri ; Klinkenberg, Kerstin ; Blankertz, Benjamin (2017)

The human factor plays the key role for safety in many industrial and civil every-day operations in our technologized world. Human failure is more likely to cause accidents than technical failure, e.g. in the challenging job of tugboat captains. Here, cognitive workload is crucial, as its excess is a main cause of dangerous situations and accidents while being highly participant and situation d...

Decoding implicit information from the electroencephalogram with methods from brain-computer interfacing

Wenzel, Markus (2017)

Research on brain-computer interfacing (BCI) has demonstrated that specific brain activity patterns can be detected in the electroencephalogram (EEG) with multivariate methods from machine learning and signal processing in real-time. Objective. This direct access to the neural processes potentially provides an opportunity to learn about the users of technical applications in a novel way. In thi...

Brain-computer interfaces for cognitive neuroscience and advanced mental state assessment

Schultze-Kraft, Matthias (2016)

Advancements in machine learning in combination with fundamental research in cognitive neuroscience have put forth application areas for brain-computer interfaces (BCIs) that go beyond communication and control. The ability to decode covert mental states and intentions from the electroencephalogram (EEG) in real-time – hence, to study the "brain at work" – establishes the basis for multifaceted...
