When elements appear in quick succession they can integrate across space and time. Using high-density EEG techniques we show that such non-retinotopic feature integration is not time-locked to stimulus onset, but has a timing of its own. We presented a cen ...
Recent philosophical and neuroscientific theories converge on the assumption that the basic foundations of self-consciousness lie in those brain systems that represent the body. Neurological cases in which this basic bodily self-consciousness is disturbed ...
The complexity of processes occurring in the brain is an intriguing issue not just for scientists and medical doctors, but the humanity in general. The cortex ability to perceive and analyze an enormous amount of information in an instance of time, the par ...
Four experiments examined the disruptive effects of selective lesions in limbic thalamic nuclei on retrosplenial cortex function, as characterized by striking changes in immediate-early gene activity. Major goals were to test the specificity of these retro ...
A number of electrophysiological studies have been conducted in recent years in order to clarify the dynamics of visual motion processing in the human brain. Using a variety of event-related potential (ERP) measures, several parameters such as onset, offse ...
This work examines the influence of changes in baseline activity on the intrinsic functional connectivity fMRI (fc-fMRI) in humans. Baseline brain activity was altered by inducing anesthesia (sevoflurane end-tidal concentration 1%) in human volunteers and ...
The question of how people recognize themselves and separate themselves from the environment and others has long intrigued philosophers and scientists. Recent findings have linked regions of the 'default brain' or 'intrinsic system' to self-related process ...
The relationship between electrophysiological and functional magnetic resonance imaging (fMRI) signals remains poorly understood. To date, studies have required invasive methods and have been limited to single functional regions and thus cannot account for ...
Human experience takes place in the line of mental time (MT) created through 'self-projection' of oneself to different time-points in the past or future. Here we manipulated self-projection in MT not only with respect to one's life events but also with res ...
When presented with dynamic scenes, the brain integrates visual elements across space and time. Such non-retinotopic processing has been intensively studied from a psychophysical point of view, but little is known about the underlying neural processes. Her ...
