Using Time-To-Contact information to assess potential collision modulates both visual and temporal prediction networks

Fri, 05 Sep 2008 00:00:00 +0100

Status : Accepted
Abstract: Accurate estimates of the time-to-contact (TTC) of approaching objects are crucial for survival. We used an ecologically valid driving simulation to compare and contrast the neural substrates of egocentric (head-on approach) and allocentric (lateral ...

Feeling present in arousing virtual reality worlds: prefrontal brain regions differentially orchestrate presence experience in adults and children

Mon, 25 Aug 2008 00:00:00 +0100

Status : Published
Abstract: Virtual reality (VR) is a powerful tool for simulating aspects of the real world. The success of VR is thought to depend on its ability to evoke a sense of "being there", that is, the feeling of "Presence". In view of the rapid progress in the develo...

Interactions between posterior gamma and frontal alpha/beta oscillations during imagined actions

Wed, 20 Aug 2008 00:00:00 +0100

Status : Published
Abstract: Several studies have revealed that posterior parietal and frontal regions support planning of hand movements but far less is known about how these cortical regions interact during the mental simulation of a movement. Here, we have used magnetoencepha...

Towards a digital body: the virtual arm illusion

Wed, 20 Aug 2008 00:00:00 +0100

Status : Published
Abstract: The integration of the human brain with computers is an interesting new area of applied neuroscience, where one application is replacement of a person’s real body by a virtual representation. Here we demonstrate that a virtual limb can be made ...

Learning by doing and learning by thinking: An fMRI study of combining motor and mental training

Wed, 18 Jun 2008 00:00:00 +0100

Status : Published
Abstract: The current study investigated behavioral and neural effects of motor, mental, and combined motor and mental training on a finger tapping task. The motor or mental training groups trained on a finger-sequence for a total of 72 min over six weeks. The...

Event related potentials reveal that increasing perceptual load leads to increased responses for target stimuli and decreased responses for irrelevant stimuli

Fri, 23 May 2008 00:00:00 +0100

Status : Published
Abstract: Lavie and colleagues (1995, JEP:HPP 9: 497-) have suggested that perceptual processing is influenced by perceptual load. Specifically, relevant information receives additional processing in high load situations exhausting the available capacity. On ...

Independent delta/theta rhythms in the human hippocampus and entorhinal cortex

Thu, 22 May 2008 00:00:00 +0100

Status : Published
Abstract: Theta oscillations in the medial temporal lobe (MTL) of mammals are involved in various functions such as spatial navigation, sensorimotor integration, and cognitive processing. While the theta rhythm was originally assumed to originate in the medial...

Human aging magnifies genetic effects on executive functioning and working memory

Tue, 06 May 2008 00:00:00 +0100

Status : Published
Abstract: We demonstrate that common genetic polymorphisms contribute to the increasing heterogeneity of cognitive functioning in old age. We assess two common Val/Met polymorphisms, one affecting the Catechol-O-Methyltransferase (COMT) enzyme, which degrades ...

Sequential activation of human oculomotor centers during planning of visually-guided eye movements: a combined fMRI-MEG study.
