Studying clinical populations who engage in compulsive activities may represent an ecologically valid approach to investigating the neuroplasticity of multisensory integration. These works may not be reposted without the explicit permission of the copyright holder. Development of intersensory perception in human infants. However, little is known about the neural correlates of automatized drug-taking skills and drug-related action knowledge in humans. Heterochrony and cross-species intersensory matching by infant vervet monkeys.
A block-design odour localizer was presented to localize the piriform cortex primary olfactory cortex. Cocaine: Effects on the developing brain. By contrast, recent insights from neuroscience have shown that a broad spectrum of behaviors can become habitual and, thus, resistant to change. Cocaine: Effects on the developing brain. The audio-visual temporal binding window narrows in early childhood.
Investigating the neural specificity, connectivity, and plasticity of human multisensory object processing. He has conducted extensive research on auditory and audio-visual perception, short-term memory and cortical oscillations in humans, using magnetoencephalography and functional magnetic resonance imaging. We conclude with a discussion of outstanding challenges and future research, directions, which can inform future neuroimaging studies as well as the design of treatment and, prevention programs. Since 2005 he has headed the Crossmodal Neuroimaging Lab at the Institute of Medical Psychology, Goethe University, Frankfurt, Germany. Naumer studied biology, philosophy, and psychology at the universities of Freiburg and Landau in Germany. Its neural underpinnings have been extensively studied in animal experiments and human neuroimaging studies, which have demonstrated that during addiction various reorganizational processes hijack the reward and habit systems.

Prenatal cocaine exposure and stimulus-seeking behaviors between 4- and 10-months: A continuation of poor arousal regulation as neonates. This chapter reviews the evidence for an involvement of gamma-band activity in multisensory integration. Naumer studied biology, philosophy, and psychology at the universities of Freiburg and Landau in Germany. The aim of the present study was to investigate the influence of evaluative conditioning on cortical plasticity in human audiovisual object processing. In these regions, epoch-by-epoch predictable information was positively correlated with source power in the alpha and beta frequency range as well as autocorrelation decay time.
It has been suggested that the performance of habitual behavior is guided by automatized action schemata, a constellation of stimuli-bound specific skills which ensure the efficient initiation and execution of drug-using behavior. Activations in nine out of these twelve regions met the max-criterion A V for multisensory integration. Cognitive Brain Research, 14, 41-63.

For some visual stimuli, he perceives a strong and automatic olfactory percept, which has existed throughout his life. Journal of Experimental Child Psychology. Building on previous model-building reviews on the topic, we then outline a simplified model that includes the key modulatory factors and a tentative ranking of, their relative impact. Thus, the brain's ability to compare across the senses and to integrate the information they provide is not only a way to examine the accuracy of any individual sensory channel but also a way to enhance the collective information they make available to the brain.

Annals of the New York Academy of Sciences, Vol. In 2004 he was appointed Full Professor and Director of the Institute of Medical Psychology at Goethe University in Frankfurt am Main, Germany. To illustrate these relationships, a psychophysiology practical was introduced in the first semester. Evidence will be presented from studies in both human and nonhuman primates at different levels of analysis ranging from intracranial electrophysiological recordings to non-invasive electro- or magnetoencephalography, functional magnetic resonance imaging, behavioral approaches, and computational modeling. The ontogeny of human multisensory object perception: A constructivist account.
Students evaluated the practical positively. The continuing obsession with sensory systems is as much a re? This work has identified both multisensory integration regions and crossmodal influences in brain areas traditionally thought to be specific to one sensory modality. These results indicate that emotional valence modulates object-related audiovisual processing. Multisensory integration and predictive coding would be effective strategies for the perception of near-threshold stimuli, but they come at the cost of integrating irrelevant information. We did not find differences in reaction times or accuracy between gender congruent or incongruent stimuli. Infancy, 16 4 , 331—367.
Furthermore, several factors have been identified that enhance integration such as spatio-temporal stimulus coincidence and semantic congruency. Rationale: Behavioral experiments have demonstrated that the sensory modality of presentation modulates drug cue reactivity. Nevertheless, it was the concentrated effort on the operational principles of in- vidual senses that provided the depth of understanding necessary to inform current efforts to reveal how they act cooperatively. Similarly, auditory regions of interest of the right middle superior temporal gyrus and sulcus exhibited repetition suppression to auditory repetitions and repetition enhancement to visual repetitions. The most common form of synaesthesia is grapheme—colour synaesthesia. We first investigated changes in prevalence and reaction times due to perceived gender discrepancy during the McGurk-percept.
To date, noninvasive neuroimaging research on multisensory perception has focused on cortical activations. In contrast, the interruption or modification of already triggered automatized action representations require increased neural resources. Dual-coding theory Paivio, 1986 postulates that the human mind represents objects not just with an analogous, or semantic code, but with a perceptual representation as well. The E-mail message field is required. The development of multisensory temporal perception. In contrast, sensory and motor aspects of addiction have largely been neglected even though they may be highly relevant for the development and preservation of addiction. In order to act effectively, we employ several of our senses in parallel.
