Although human cognition often occurs during dynamic motor actions, most studies of brain dynamics examine subjects in static seated or prone conditions. EEG signals have historically been considered to be too noise allow recording locomotion. Here we applied a channel-based artifact template regression procedure and subsequent spatial filtering approach remove gait-related movement from recorded walking running. We first used stride time warping gait high-density visual oddball...

The ability to cognitively regulate emotional responses aversive events is essential for mental and physical health. One prerequisite of successful emotion regulation the awareness states, which in turn associated with bodily signals [interoceptive (IA)]. This study investigated neural dynamics reappraisal 28 participants who differed respect IA. Electroencephalography was used characterize time course regulation. We found that accompanied by reduced arousal significant modulation late...

Abstract Recent developments in EEG hardware and analyses approaches allow for recordings both stationary mobile settings. Irrespective of the experimental setting, are contaminated with noise that has to be removed before data can functionally interpreted. Independent component analysis (ICA) is a commonly used tool remove artifacts such as eye movement, muscle activity, external from analyze activity on level effective brain sources. The effectiveness filtering one key preprocessing step...

Neuroarchitecture uses neuroscientific tools to better understand architectural design and its impact on human perception subjective experience. The form or shape of the built environment is fundamental design, but not many studies have shown different forms inhabitants' emotions. This study investigated neurophysiological correlates interior perceivers' affective state accompanying brain activity. To naturalistic three-dimensional (3D) forms, it essential perceive from perspectives. We...

Abstract In many theories of emotions the representations bodily responses play an important role for subjective feelings. We tested hypothesis that perception states is positively related to experienced intensity feelings as well activity first‐order and second‐order brain structures involved in processing Using a heartbeat task, subjects were separated into groups with either high or poor interoceptive awareness. During emotional picture presentation we measured high‐density EEG used...

Human cognition has been shaped both by our body structure and its complex interactions with environment. Our is thus inextricably linked to own others’ motor behavior. To model brain activity associated natural cognition, we propose recording the concurrent dynamics movements of human subjects performing normal actions. Here tested feasibility such a mobile brain/body (MoBI) imaging approach high-density electroencephalographic (EEG) standing or walking on treadmill while visual oddball...

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> Spatial filtering (SF) constitutes an integral part of building EEG-based brain–computer interfaces (BCIs). Algorithms frequently used for SF, such as common spatial patterns (CSPs) and independent component analysis, require labeled training data identifying filters that provide information on a subject's intention, which renders these algorithms susceptible to overfitting artifactual EEG...

The study of brain-computer interfaces (BCIs) has undergone 30 years intense development and grown into a rich diverse field. BCIs are technologies that enable direct communication between the human brain external devices. Conventionally, wet electrodes have been employed to obtain unprecedented sensitivity high-temporal-resolution activity; recently, growing availability various sensors can be used detect high-quality signals in wide range clinical everyday environments is being exploited....

Abstract Maintaining spatial orientation while travelling requires integrating information encountered from an egocentric viewpoint with accumulated represented within and/or allocentric reference frames. Here, we report changes in high-density EEG activity during a virtual tunnel passage task which subjects respond to postnavigation homing challenge distinctly different ways—either compatible continued experience of the environment solely perspective or as if also maintaining their original...

Significance The human brain continuously and automatically processes information concerning its internal external context. We demonstrate the elicitation subsequent detection decoding of such “automatic interpretations” by means context-sensitive probes in an ongoing human–computer interaction. Through a sequence probe–interpretation cycles, computer accumulates responses over time to model operator’s cognition, even without that person being aware it. This brings cognition directly into...

The notion of a saliency-based processing architecture [1] underlying human vision is central to number current theories visual selective attention [e.g., 2]. On this view, focal-attention guided by an overall-saliency map the scene, which integrates (sums) signals from pre-attentive sensory feature-contrast computations (e.g., for color, motion, etc.). By linking Posterior Contralateral Negativity (PCN) component reaction time (RT) performance, we tested one specific prediction such...

Anticipating meaningful actions in the environment is an essential function of brain. Such predictive mechanisms originate from motor system and allow for inferring environmental affordances, potential to act within a specific environment. Using architecture, we provide unique perspective on ongoing debate cognitive neuroscience philosophy whether cognition depends movement or decoupled our physical structure. To investigate processes associated with architectural used mobile brain/body...

One of the most firmly established factors determining speed human behavioral responses toward action-critical stimuli is spatial correspondence between stimulus and response locations. If both locations match, time taken for production markedly reduced relative to when they mismatch, a phenomenon called Simon effect. While there consensus that this stimulus-response (S-R) conflict associated with brief (4-7 Hz) frontal midline theta (fmθ) complexes generated in medial cortex, it remains...

The non-invasive recording and analysis of human brain activity during active movements in natural working conditions is a central challenge Neuroergonomics research. Existing imaging approaches do not allow for an investigation dynamics behavior because their sensors cannot follow the movement signal source. However, that require operator to react fast adapt dynamically changing environment occur frequently environments like assembly-line work, construction trade, health care, but also...

Abstract Advancements in hardware technology and analysis methods allow more mobility electroencephalography (EEG) experiments. Mobile Brain/Body Imaging (MoBI) studies may record various types of data such as motion or eye tracking addition to neural activity. Although there are options available analyze EEG a standardized way, they do not fully cover complex multimodal from mobile We thus propose the BeMoBIL Pipeline, an easy-to-use pipeline MATLAB that supports time-synchronized handling...

Three experiments investigated spatial orientation in a virtual navigation task. Subjects had to adjust homing vector indicating their end position relative the origin of path. It was demonstrated that sparse visual flow sufficient for accurate path integration. Moreover, subjects were found prefer distinct egocentric or allocentric reference frame solve "Turners" reacted as if they taken on new during turns by mentally rotating sagittal axis (egocentric frame). "Nonturners," contrast,...

In cross-dimensional visual search tasks, target discrimination is faster when the previous trial contained a defined in same dimension as current trial. The dimension-weighting account (DWA; A. Found & H. J. Müller, 1996) explains this intertrial facilitation by assuming that dimensions are weighted at an early perceptual stage of processing. Recently, view has been challenged models claiming effects generated later stages follow attentional selection (K. Mortier, Theeuwes, P. Starreveld,...
