Perceiving while acting: How visual selection is tuned to action intentions
by Agnieszka Wykowska
Department of General and Experimental Psychology, Ludwig-Maximilians-University Munich, Germany
Imagine you’re playing baseball and you’re just about to strike an approaching ball with your bat. How does your brain plan that action and what parameters need to be specified to perform it efficiently? Apart from the obvious control of the motor commands, the brain needs also to adjust perceptual processing to fit the goals of the planned action. Throughout lifelong experience, humans learn that for various actions different perceptual parameters are important and relevant. This implies that perceptual selection can be tuned to action planning. That is, in the baseball example - when you plan an action, depending on whether you plan to hit the ball or catch it, different perceptual aspects of the ball will be relevant, and prioritized accordingly. In catching the ball, grip aperture is important, and hence, size and shape of the ball needs to be processed with priority. In case of hitting the ball, its location is the most important feature. In neither of the cases color of the ball is relevant. We postulate that the so-called intentional weighting mechanism operates at the level of processing of perceptual information in order to tune perception to action plans. The idea is that planning a particular action should affect visual perception in a way that perceptual dimensions, which are potentially relevant for the intended action receive a higher weight than those dimensions that are not action-relevant. This should allow efficient delivery of perceptual parameters for online action control. ...

Perception of effort and movement-related cortical potential during weight lifting
by Helma M. de Morree
Department of Medical Psychology and Neuropsychology, Center of Research on Psychology in Somatic Diseases (CoRPS),Tilburg University, The Netherlands
Perception of effort, the conscious sensation of how heavy and
strenuous a physical task is (Borg, 1998), is an important aspect of our subjective experience of volition. It provides information about task difficulty, is involved in the adaptive expenditure of energy, and contributes to the feeling of conscious will (Preston & Wegner, 2009). Nonetheless, little is known about the neurophysiology of perception of effort. It is thought that the signal underlying perception of effort arises in the brain from corollary discharges of the central motor command. This corollary discharge theory suggests that perception of effort should be significantly correlated with the magnitude of central motor command. However, very little direct evidence exists that perception of effort indeed correlates with movement-related brain activity (Barry & Enoka, 2007; Enoka & Stuart, 1992). ...

High-frequency neural activity modulated by crossmodal haptic-to-auditory priming
by Till R. Schneider
Cognitive and Clinical Neurophysiology Group / University Medical Center Hamburg-Eppendorf
Multisensory processing can be beneficial for the perception of objects, especially if the input of one modality alone is not sufficient for the perception process. In this case, information from different sensory modalities is combined to improve object perception. In our study published in the Journal of Neuroscience we investigated the influence of a haptically explored cue on auditory perception of objects in a crossmodal semantic priming paradigm (Schneider et al., 2011). Crossmodal semantic priming allows information transfer between sensory modalities. On the behavioral level it describes facilitated processing of a stimulus in one sensory modality when preceded by related input from another modality. Haptic cues served as primes and complex sounds of objects as targets. Haptic and auditory stimuli were either semantically congruent or incongruent. We recorded high-density EEG while participants were performing the priming task and observed enhanced neural activity in the gamma-band (60-80 Hz) in response to complex auditory stimuli preceded by semantically congruent haptic cues. Source analysis of this effect revealed enhanced activity in classic multisensory regions in lateral temporal cortex. These findings imply a special role for high frequency neuronal activity for multisensory processing in high-level cortical areas. ...

When processing the melody of speech is atypical: ERP insights into emotional prosody processing in Williams syndrome
by Ana Patrícia Teixeira Pinheiro
Neuropsychophysiology Laboratory, School of Psychology, University of Minho, Braga, Portugal
Cognitive Neuroscience Laboratory, Department of Psychiatry, Harvard Medical School, Boston, USA
Williams syndrome is a genetic neurodevelopmental disorder resulting from a submicroscopic deletion of approximately 1.6 Mb including 24-28 genes on the long arm of chromosome 7 (7q11.23) (Ewart et al., 1993). This syndrome is characterized by an uneven cognitive profile and intellectual disability (Martens, Wilson, & Reutens, 2008). In spite of early claims proposing the modular preservation of language in WS coexisting with severe deficits in visuospatial abilities, a large body of recent research has questioned these claims and demonstrated that language abilities of individuals with Williams syndrome are in line with their general cognitive abilities. Abnormalities have been shown in specific language subcomponents, including deficits in the recognition of emotion in speech stimuli, i.e. emotional prosody (Catterall et al., 2006; Plesa-Skwerer et al., 2006, 2007). ...

Visual processing in the auditory cortex of cochlear-implant users
by Pascale Sandmann
Carl von Ossietzky University of Oldenburg, Germany
Cochlear-implants can be used to restore hearing in individuals with profound hearing loss. Currently, more than 200,000 otherwise deaf individuals are benefiting from this technology. However, there is a high degree of variability in performance outcomes across implant users. Our EEG study suggests that this variability is related to reorganisation within the auditory cortex. In particular, our results show that cochlear-implant users recruit the auditory cortex misleading to assist the processes involved in visual stimulation. This visual activation of the auditory cortex is more pronounced in individuals who have a moderate rather than a good ability to recognise speech. ...

Sleep and functional Imaging
by Michael Czisch, Victor I. Spoormaker, Katia C. Andrade, Renate Wehrle, Philipp G. Sämannn
Max Planck Institute of Psychiatry, Munich, Germany
To study the brain’s activity during sleep, functional MRI in combination with simultaneous polysomnographic recordings has been used in the last decade as a combination of methods with high spatial and temporal resolution. Recent data analysis tools have opened a window to determine cerebral functional networking in task-free fMRI data, ideally suited for an application in sleeping subjects. Data are discussed which are derived from complementary analyses. We describe how reorganization of functional cerebral communication may further our understanding of phenomena like fading of consciousness during sleep, and how information reprocessing during sleep may be linked to global flow of information in light sleep and more local reprocessing in deep sleep. ...

How DC-recorded slow potentials can aid in studying dynamic retrieval-control processes
by Jasmin M. Kizilirmak
Philipps-University Marburg, Germany
In our daily life, we are constantly faced with the necessity of
selecting relevant stimuli, tasks, and memories to achieve our goals. Sometimes, we even need to focus on information we had to ignore just previously. What kind of control mechanisms enable us to alternately switch between what is selected and what is ignored? In the field of selective attention and task switching, by changing which stimulus/task is relevant from trial to trial, evidence has been obtained for the inhibition of irrelevant information by means of ‘negative priming‘ [1], for the enhancement of the relevant information [2], and for both in conjunction [3]. In contrast, for memory retrieval, research has predominately focused on paradigms where subjects did never have to switch between which information has to be retrieved and which to be ignored until final esting [4]. ...

Combining EEG and fMRI signals in both humans and rodents: Advantages and limitations
by Jorge Riera
Department of Functional Brain Imaging, Institute of Development, Aging and Cancer, Tohoku University
Abstract: There exist two prevailing tools to study the mechanisms that lie behind the brain functioning in healthy individuals and patients: the electroencephalogram (EEG) and the functional magnetic resonance imaging (fMRI). For about a decade, physicists and biomedical engineers have struggled to develop compatible devices and methods for the right combination of these two imaging modalities. Recent major efforts by different groups have been on developing a) means to perform EEG-fMRI concurrent recordings in other species, b) forward-generative models that comprise both the physical principles of data genesis and the physiological causal mechanisms, and c) strategies for statistical inference about these models from simultaneously recorded data. Here, I discuss recent achievements by members of my group in Tohoku University, Sendai Japan, which in one way or another dealt with interesting problems related to these emergent research/technological lines. ...

Multi-stability and non-linearity of large-scale cortical rhythms
by Michael Breakspear
Synopsis: Electroencaphalograpic (EEG) data arises from electrical currents averaged over large populations of neocortical neurons. The basic statistical and dynamical properties of EEG data can hence provide vital insights into the nature of large-scale neural activity and inform fundamental questions in computational neuroscience. I review two recent studies of EEG data - one acquired at rest and the other following sensory perturbations - that evidence a surprising richness of complexity and nonlinearity. These findings may have important implications for computational accounts of human cognition. ...

Examining the benefits of sparce scanning and ICA-based ERP extraction
in combined EEG-fMRI
by Aureliu Lavric (a,b), Nino Bregadze (a) and Abdelmalek Benattayallah (b)
(a) Cognitive Neurophysiology Laboratory, (b) School of Psychology, University of Exeter, UK
Though promising, concurrent EEG-fMRI is challenging, because it leads to additional artifacts relative to those seen when the techniques are used separately; these extra artifacts are particularly severe for EEG. One of them, cardioballistic artifact- voltage resulting from peripheral effects of cardiac activity such as pulsation of the scalp with EEG electrodes on it in the scanner magnet- is very difficult or impossible to avoid. In contrast, ‘gradient’ artifact-voltage induced by rapid switching of spatial encoding (gradient) magnetic fields- is largely under the experimenter’s control. Indeed, by spacing out the acquisition of fMRI images, one can have EEG stretches that are gradient artifact-free. ...

Brain Oscillatory Substrates of Visual Short-Term Memory Capacity
by Paul Sauseng, Wolfgang Klimesch, Kirstin F. Heise, Walter R. Gruber, Elisa Holz, Ahmed A. Karim, Mark Glennon, Christian Gerloff, Niels Birbaumer and Friedhelm C. Hummel
We are constantly bombarded with millions of sensory stimuli entering the visual system. Only a very small fraction of this input, however, can be held in memory for a short period of time. Nowadays it is well established that the number of visual items that can be stored in human short-term memory lies in a range of about four, i.e. our short-term memory’s capacity is limited to transiently maintain only up to four visual stimuli at the same time. But why is human visual short-term memory capacity so staggering small? ...

Causal Influence of Gamma Oscillations on the Sensorimotor-Rhythm
by Moritz Grosse-Wentrup, Bernhard Schölkopf & Jeremy Hill
Department Empirical Inference, Max Planck Institute for Biological Cybernetics, Tübingen (Germany)
High-frequency oscillations of the electromagnetic field of the brain, commonly referred to as γ-oscillations, are believed by some authors to play a central role for information processing
in the brain. However, while γ-oscillations have been shown to be correlated with a variety of brain signals and cognitive tasks, to date no empirical evidence for a causal role of γ-oscillations has been presented. ...

University Medical Center Hamburg-Eppendorf, Hamburg (Germany)
The acquisition of electroencephalography (EEG) during Functional Magnetic Resonance Imaging (fMRI) measurement offers the chance to combine the high spatial resolution of the fMRI with the great time resolution of the EEG. It provides the possibility of enhancing the current understanding of brain (dys-) function in a non-invasive way (1). However, the quality of the EEG data ac-quired in a MRI scanner is limited by several artifacts which are directly or indirectly related to the magnetic field of the scanner. ...
