Focusing effects of L‐dopa in Parkinson's disease

Bernard Ng, Samantha Palmer, Rafeef Abugharbieh, Martin J. McKeown

Previous fMRI motor studies in Parkinson's disease (PD) have suggested that L‐dopa may “normalize” areas of hypo‐ and hyperactivity. However, results from these studies, which were largely based on analyzing BOLD signal amplitude, have been conflicting. Examining only amplitude changes at distinct loci may thus be inadequate in fully capturing the activation changes induced by L‐dopa. In this article,...

Pathological amygdala activation during working memory performance: Evidence for a pathophysiological trait marker in bipolar affective disorder

Oliver Gruber, Heike Tost, Ilona Henseler, Christine Schmael, more

Human Brain Mapping > 31 > 1 > 115 - 125

Recent evidence suggests that deficits of working memory may be a promising neurocognitive endophenotype of bipolar affective disorder. However, little is known about the neurobiological correlates of these deficits. The aim of this study was to determine possible pathophysiological trait markers of bipolar disorder in neural circuits involved in working memory. Functional magnetic resonance imaging...

Improving fMRI sensitivity by normalization of basal physiologic state

Hanzhang Lu, Uma S. Yezhuvath, Guanghua Xiao

Human Brain Mapping > 31 > 1 > 80 - 87

The power of fMRI in assessing neural activities is hampered by inter‐subject variations in basal physiologic parameters, which may not be related to neural activation but has a modulatory effect on fMRI signals. Therefore, normalization of fMRI signals with these parameters is useful in reducing variations and improving sensitivity of this important technique. Recently, we have shown that basal venous...

Cancellation of EEG and MEG signals generated by extended and distributed sources

Seppo P. Ahlfors, Jooman Han, Fa‐Hsuan Lin, Thomas Witzel, more

Human Brain Mapping > 31 > 1 > 140 - 149

Extracranial patterns of scalp potentials and magnetic fields, as measured with electro‐ and magnetoencephalography (EEG, MEG), are spatially widespread even when the underlying source in the brain is focal. Therefore, loss in signal magnitude due to cancellation is expected when multiple brain regions are simultaneously active. We characterized these cancellation effects in EEG and MEG using a forward...

Specialization in the default mode: Task‐induced brain deactivations dissociate between visual working memory and attention

Jutta S. Mayer, Alard Roebroeck, Konrad Maurer, David E.J. Linden

Human Brain Mapping > 31 > 1 > 126 - 139

The idea of an organized mode of brain function that is present as default state and suspended during goal‐directed behaviors has recently gained much interest in the study of human brain function. The default mode hypothesis is based on the repeated observation that certain brain areas show task‐induced deactivations across a wide range of cognitive tasks. In this event‐related functional resonance...

Crossmodal influences in somatosensory cortex: Interaction of vision and touch

Jennifer K. Dionne, Sean K. Meehan, Wynn Legon, W. Richard Staines

Human Brain Mapping > 31 > 1 > 14 - 25

Previous research has shown that information from one sensory modality has the potential to influence activity in a different modality, and these crossmodal interactions can occur early in the cortical sensory processing stream within sensory‐specific cortex. In addition, it has been shown that when sensory information is relevant to the performance of a task, there is an upregulation of sensory cortex...

The effect of presentation paradigm on syntactic processing: An event‐related fMRI study

Donghoon Lee, Sharlene D. Newman

Human Brain Mapping > 31 > 1 > 65 - 79

An event‐related fMRI study was conducted to investigate the effect of two different sentence presentation paradigms—rapid serial visual presentation (RSVP) and whole sentence presentation—on syntactic processing. During scanning, sentences were presented using one of the two presentation paradigms and were followed by a short delay and a probe to verify sentence comprehension. The delay was included...

Tuning‐in to the beat: Aesthetic appreciation of musical rhythms correlates with a premotor activity boost

Katja Kornysheva, D.Yves von Cramon, Thomas Jacobsen, Ricarda I. Schubotz

Human Brain Mapping > 31 > 1 > 48 - 64

Listening to music can induce us to tune in to its beat. Previous neuroimaging studies have shown that the motor system becomes involved in perceptual rhythm and timing tasks in general, as well as during preference‐related responses to music. However, the role of preferred rhythm and, in particular, of preferred beat frequency (tempo) in driving activity in the motor system remains unknown. The goals...

article

Functional specialization and dynamic resource allocation in visual cortex

Gijs Plomp, Cees van Leeuwen, Andreas A. Ioannides

Human Brain Mapping > 31 > 1 > 1 - 13

We studied the spatiotemporal characteristics of cortical activity in early visual areas and the fusiform gyri (FG) by means of magnetoencephalography (MEG). Subjects performed a visual classification task, in which letters and visually similar pseudoletters were presented in different surrounds and under different task demands. The stimuli appeared in a cued half of the visual field (VF). We observed...

Somatosensory working memory performance in humans depends on both engagement and disengagement of regions in a distributed network

Saskia Haegens, Daria Osipova, Robert Oostenveld, Ole Jensen

Human Brain Mapping > 31 > 1 > 26 - 35

Successful working memory (WM) requires the engagement of relevant brain areas but possibly also the disengagement of irrelevant areas. We used magnetoencephalography (MEG) to elucidate the temporal dynamics of areas involved in a somatosensory WM task. We found an increase in gamma band activity in the primary and secondary somatosensory areas during encoding and retention, respectively. This was...

Neural representation of anxiety and personality during exposure to anxiety‐provoking and neutral scenes from scary movies

Thomas Straube, Sandra Preissler, Judith Lipka, Johannes Hewig, more

Human Brain Mapping > 31 > 1 > 36 - 47

Some people search for intense sensations such as being scared by frightening movies while others do not. The brain mechanisms underlying such inter‐individual differences are not clear. Testing theoretical models, we investigated neural correlates of anxiety and the personality trait sensation seeking in 40 subjects who watched threatening and neutral scenes from scary movies during functional magnetic...

Comparing isotropic and anisotropic smoothing for voxel‐based DTI analyses: A simulation study

Wim Van Hecke, Alexander Leemans, Steve De Backer, Ben Jeurissen, more

Human Brain Mapping > 31 > 1 > 98 - 114

Voxel‐based analysis (VBA) methods are increasingly being used to compare diffusion tensor image (DTI) properties across different populations of subjects. Although VBA has many advantages, its results are highly dependent on several parameter settings, such as those from the coregistration technique applied to align the data, the smoothing kernel, the statistics, and the post‐hoc analyses. In particular,...

Spatial‐temporal dynamics of cortical activity underlying reaching and grasping

Naznin Virji‐Babul, Alexander Moiseev, Teresa Cheung, Daniel Weeks, more

Human Brain Mapping > 31 > 1 > 160 - 171

How humans understand the actions and intentions of others remains poorly understood. Here we report the results of a magnetoencephalography (MEG) experiment to determine the temporal dynamics and spatial distribution of brain regions activated during execution and observation of a reach to grasp motion using real world stimuli. We show that although both conditions activate similar brain areas, there...

The neural origins of superficial and individuated judgments about ingroup and outgroup members

Jonathan B. Freeman, Daniela Schiller, Nicholas O. Rule, Nalini Ambady

Human Brain Mapping > 31 > 1 > 150 - 159

We often form impressions of others based on superficial information, such as a mere glimpse of their face. Given the opportunity to get to know someone, however, our judgments are allowed to become more individuated. The neural origins of these two types of social judgment remain unknown. We used functional magnetic resonance imaging to dissociate the neural mechanisms underlying superficial and...

Dissecting structure–function interactions in acute optic neuritis to investigate neuroplasticity

Thomas Jenkins, Olga Ciccarelli, Ahmed Toosy, Katherine Miszkiel, more

Human Brain Mapping > 31 > 2 > 276 - 286

Structural MRI, electrophysiology, and functional MRI (fMRI) elucidate different aspects of damage and repair in demyelinating diseases. We combined them to investigate why patients with optic neuritis (ON) exhibit a wide variation in severity of acute visual loss, with the following objectives: (1) To determine how structural and electrophysiological changes in the anterior and posterior visual pathways...

The impact of dystrobrevin‐binding protein 1 (DTNBP1) on neural correlates of episodic memory encoding and retrieval

Markus Thimm, Axel Krug, Valentin Markov, Sören Krach, more

Human Brain Mapping > 31 > 2 > 203 - 209

Episodic memory impairment is a frequently reported symptom in schizophrenia. It has been shown to be associated with reduced neural activity of the hippocampus and prefrontal cortex. Given the high heritability of schizophrenia the question arises if alterations in brain activity are modulated by susceptibility genes and might be detectable in healthy risk allele carriers. The present study investigated...

Impact of schizophrenia‐risk gene dysbindin 1 on brain activation in bilateral middle frontal gyrus during a working memory task in healthy individuals

Valentin Markov, Axel Krug, Sören Krach, Andreas Jansen, more

Human Brain Mapping > 31 > 2 > 266 - 275

Working memory (WM) dysfunction is a hallmark feature of schizophrenia. Functional imaging studies using WM tasks have documented both prefrontal hypo‐ and hyperactivation in schizophrenia. Schizophrenia is highly heritable, and it is unclear which susceptibility genes modulate WM and its neural correlates. A strong linkage between genetic variants in the dysbindin 1 gene and schizophrenia has been...

ERP generator anomalies in presymptomatic carriers of the Alzheimer's disease E280A PS‐1 mutation

María A. Bobes, Yuriem Fernández García, Francisco Lopera, Yakeel T. Quiroz, more

Human Brain Mapping > 31 > 2 > 247 - 265

Although subtle anatomical anomalies long precede the onset of clinical symptoms in Alzheimer's disease, their impact on the reorganization of brain networks underlying cognitive functions has not been fully explored. A unique window into this reorganization is provided by presymptomatic cases of familial Alzheimer's disease (FAD). Here we studied neural circuitry related to semantic processing in...
