Visual feedback alters force control and functional activity in the visuomotor network after stroke. [PDF]
, 2018 Modulating visual feedback may be a viable option to improve motor function after stroke, but the neurophysiological basis for this improvement is not clear.

fMRI Adaptation: Stimulus Specific or Processing Load Specific? [PDF]
The Journal of Neuroscience, 2007 Repetition suppression, or fMRI-adaptation, refers to decreased neural activity for repeated versus novel stimuli as measured with functional magnetic resonance imaging (fMRI). Recently, this technique has been widely used, especially in probing the plasticity of the nervous system and ...

Prismatic adaptation modulates oscillatory EEG correlates of motor preparation but not visual attention in healthy participants [PDF]
, 2017 Prismatic adaption (PA) has been proposed as a tool to induce neural plasticity and is used to help neglect rehabilitation. It leads to a recalibration of visuo-motor coordination during pointing as well as to after-effects on a number of sensorimotor ...

Feature-Based Attention Affects Direction-Selective fMRI Adaptation in hMT+ [PDF]
Cerebral Cortex, 2012 Functional magnetic resonance adaptation has been successfully used to reveal direction-selective responses in the human motion complex (hMT+). Here, we aimed at further investigating direction-selective as well as position-selective responses of hMT+ by looking at how these responses are affected by feature-based attention.

A Dissociation of Attention and Awareness in Phase-sensitive but Not Phase-insensitive Visual Channels [PDF]
, 2010 The elements most vivid in our conscious awareness are the ones to which we direct our attention. Scientific study confirms the impression of a close bond between selective attention and visual awareness, yet the nature of this association remains ...

Reading positional codes with fMRI: Problems and solutions.
PLoS ONE, 2017 Neural mechanisms which bind items into sequences have been investigated in a large body of research in animal neurophysiology and human neuroimaging. However, a major problem in interpreting this data arises from a fact that several unrelated processes,

Functional Connectivity Linked to Cognitive Recovery After Minor Stroke
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Patients with minor stroke exhibit slowed processing speed and generalized alterations in functional connectivity involving frontoparietal cortex (FPC). The pattern of connectivity evolves over time. In this study, we examine the relationship of functional connectivity patterns to cognitive performance, to determine ...

Counterbalancing for serial order carryover effects in experimental condition orders [PDF]
, 2012 Reactions of neural, psychological, and social systems are rarely, if ever, independent of previous inputs and states. The potential for serial order carryover effects from one condition to the next in a sequence of experimental trials makes ...

Adaptive experimental condition selection in event-related fMRI [PDF]
2012 9th IEEE International Symposium on Biomedical Imaging (ISBI), 2012 Standard Bayesian analysis of event-related functional Magnetic Resonance Imaging (fMRI) data usually assumes that all delivered stimuli possibly generate a BOLD response everywhere in the brain although activation is likely to be induced by only some of them in specific brain areas.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Accurate localization of epileptogenic tubers (ETs) in patients with tuberous sclerosis complex (TSC) is essential but challenging, as these tubers lack distinct pathological or genetic markers to differentiate them from other cortical tubers.
