Book excerpt: "Although aspects of the visual image such as color, motion, form, and depth appear perceptually integrated, many are processed separately in different, specialized areas of the brain. This study investigates the differential effects of repetitive TMS (cTBS) in areas hMT+ and V1/V2 on global motion in order to reveal their roles in isoluminant chromatic compared to achromatic motion processing. Additionally, this study compares the differential effect of stimulation on motion direction versus simple detection thresholds to determine whether they have different physiological origins, since a dissociation between these two types of threshold has been established psychophysically. The report of moving or stationary phosphenes was used to localize brain areas hMT+ and V1/V2, respectively. The coil-position within each area that elicited the strongest phosphene responses was targeted for disruption by cTBS, a repetitive transcranial magnetic stimulation protocol. The vertex was used as a control for non-specific cTBS effects. Stimuli consisted of either isoluminant chromatic or achromatic random dot kinematograms (RDKs). Participants performed a motion discrimination task in which the direction of Gaussian blobs (left or right) was identified, and a simple detection task, in which the presence of a low contrast stimulus was detected regardless of motion. Thresholds were measured before and four times after cTBS stimulation within one hour to investigate the effects of cTBS on performance over time, as this has not yet been established for vision. Performances on the motion discrimination task for both achromatic and isoluminant chromatic stimuli were significantly impaired following cTBS of area hMT+. In comparison, no effect of cTBS on performance was seen for areas V1/V2 and vertex. Maximal effects occurred at 10-11 minutes after stimulation. One hour after stimulation, performance returned to baseline levels. No differential effects of cTBS between the three brain areas were observed for the detection task. This study firstly validated the use of cTBS as a tool to impair the function of area hMT+. In doing so, it provides additional evidence that area hMT+ is involved in the analysis of both achromatically as well as chromatically defined global motion. In conclusion, area hMT+ is contributing to chromatic motion seen at isoluminance. The results indicate a causal link between neural activity in area hMT+ and the perception of chromatic motion." --

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theta burst stimulation (TBS), a type of transcranial magnetic stimulation (TMS), uses repeated high-frequency bursts to induce neural noise in the cortex. An intermittent TBS (iTBS) protocol is generally considered excitatory, while continuous TBS (cTBS) is generally considered inhibitory. TBS effects are highly variable and have been primarily studied in the primary motor cortex (M1). We investigated the effects of iTBS and cTBS to the primary visual cortex (V1) on occipital Glx (glutamate and glutamine composite) and GABA+ (gamma-aminobutyric acid and macromolecules composite) concentrations compared to sham stimulation. Thirty participants received a single session of individual stereotaxically-guided TBS to the V1. Participants received either cTBS, iTBS or sham TBS. GABA+ and Glx were measured at the stimulation site using magnetic resonance spectroscopy. Baseline pre-TBS GABA+ and Glx levels were compared to those immediately post- and one hour post-TBS. The results show a trend for a decrease in GABA+ immediately following cTBS compared to one hour post-TBS and a trend for an increase in Glx immediately following iTBS compared to one hour-post TBS. There was also an increase in GABA+ from baseline to one hour-post TBS and a trend for an increase in GABA+ and Glx composite ratio levels following sham. Since there was a lack of systematic trends in the data, we suspect there is no relevant change from a single session of TBS to neurotransmitter levels in the V1. Perhaps, only repeated application of TBS may lead to substantial benefits. This indicates that a single session of TBS can be used safely in the laboratory without effects on neurotransmitter levels in the V1.

Book excerpt: During the last years repetitive transcranial magnetic stimulation has been used as a tool for the treatment of neuropsychiatric disorders. However, the mechanisms by which it exerts its effects and the modulation that it induces in the brain are not completely understood. This book offers an overview of a novel form of repetitive transcranial magnetic stimulation called theta-burst applied over the human motor cortex. Molecular findings in animal models as well as clinical applications are described and discussed. Furthermore, it provides evidence for the modulation of neural activity induced by theta-burst by means of functional magnetic resonance imaging (fMRI) during human motor activity. The data suggest that the combination of theta-burst and fMRI might be useful to monitor treatment effects, which may have clinical implications.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes a series of studies, involving healthy subjects and a carefully selected stroke patient, in which the techniques of Transcranial Magnetic Stimulation (TMS) and Signal Detection Theory (SDT) were combined to explore processing in the posterior parietal cortex (PPC) and the phenomenon of unilateral spatial neglect: 1) A new SDT-based TMS 'hunting' technique was developed and then employed successfully over the right PPC. This revealed a cortical node which could be modulated with 'online' 10Hz-TMS to exert control over subjects' visuospatial perception. 2) By targeting this 'hotspot' and an equivalent area in the left PPC with disruptive 'cTBS' (continuous 'Theta Burst' simulation), neglect-like effects in the healthy brain could be induced and alleviated. These effects were quantified using a newly developed, fully balanced, bihemifield detection paradigm 3) By using TMS to map visuospatial function over healthy right PPC, the 'hotspot' could be enlarged after exposure to excitatory, intermittent TBS (iTBS). 4) cTBS was applied to the left PPC of a patient with a right sided stroke and visuospatial neglect. In doing this, neglect and its alleviation were described for the first time in fully balanced SDT terms. 5) The cerebellum was targeted in healthy subjects with 1Hz inhibitory TMS which induced a shift in their subjective midline for 'imaginary' but not 'real' space, as measured with number or physical line bisection respectively. These TBS studies lend support to Kinsbourne's hemispheric rivalry hypothesis and suggest that the extent of 'spatially eloquent' cortex in the right PPC can be increased. Both strategies could be useful in larger therapeutic studies of patients suffering from USN after right sided brain injury. The final study opens up an additional therapeutic target for patients with imaginal neglect and, for the first time, implicates the cerebellum in number line bisection.

Available in PDF, EPUB and Kindle. Book excerpt: This book brings together leading investigators who represent various aspects of brain dynamics with the goal of presenting state-of-the-art current progress and address future developments. The individual chapters cover several fascinating facets of contemporary neuroscience from elementary computation of neurons, mesoscopic network oscillations, internally generated assembly sequences in the service of cognition, large-scale neuronal interactions within and across systems, the impact of sleep on cognition, memory, motor-sensory integration, spatial navigation, large-scale computation and consciousness. Each of these topics require appropriate levels of analyses with sufficiently high temporal and spatial resolution of neuronal activity in both local and global networks, supplemented by models and theories to explain how different levels of brain dynamics interact with each other and how the failure of such interactions results in neurologic and mental disease. While such complex questions cannot be answered exhaustively by a dozen or so chapters, this volume offers a nice synthesis of current thinking and work-in-progress on micro-, meso- and macro- dynamics of the brain.

Available in PDF, EPUB and Kindle. Book excerpt: Transcranial Magnetic Stimul0tion (TMS) is a non-invasive technique that has revolutionised the study of the human nervous system allowing in-depth investigations of complex voluntary motor control pathways. Today, many of the techniques used in TMS have become routine in clinical electrophysiological assessments. As an investigative tool, its application ranges from clinical diagnostics to cognitive research. Now the use of repetitive TMS (rTMS) is gaining support amongst psychiatrists as evidence suggests that it may provide an alternative to ECT in treating depression and other psychiatric disorders. This handbook brings together the basic science, fundamental principles, and essential procedures of TMS needed by all those useing or planning to use the technique clinically or in research. The final two sections focus upon current up to date knowledge of applications of the technique. Written in a digestible style by world authorities in different related specialties, the Handbook of TMS will be a valuable and comprehensive guide for clinical neurophysiologists, neuropsychiatrists, neurologists and psychiatrists.

Book excerpt: Magnetoencephalography (MEG) is an invaluable functional brain imaging technique that provides direct, real-time monitoring of neuronal activity necessary for gaining insight into dynamic cortical networks. Our intentions with this book are to cover the richness and transdisciplinary nature of the MEG field, make it more accessible to newcomers and experienced researchers and to stimulate growth in the MEG area. The book presents a comprehensive overview of MEG basics and the latest developments in methodological, empirical and clinical research, directed toward master and doctoral students, as well as researchers. There are three levels of contributions: 1) tutorials on instrumentation, measurements, modeling, and experimental design; 2) topical reviews providing extensive coverage of relevant research topics; and 3) short contributions on open, challenging issues, future developments and novel applications. The topics range from neuromagnetic measurements, signal processing and source localization techniques to dynamic functional networks underlying perception and cognition in both health and disease. Topical reviews cover, among others: development on SQUID-based and novel sensors, multi-modal integration (low field MRI and MEG; EEG and fMRI), Bayesian approaches to multi-modal integration, direct neuronal imaging, novel noise reduction methods, source-space functional analysis, decoding of brain states, dynamic brain connectivity, sensory-motor integration, MEG studies on perception and cognition, thalamocortical oscillations, fetal and neonatal MEG, pediatric MEG studies, cognitive development, clinical applications of MEG in epilepsy, pre-surgical mapping, stroke, schizophrenia, stuttering, traumatic brain injury, post-traumatic stress disorder, depression, autism, aging and neurodegeneration, MEG applications in cognitive neuropharmacology and an overview of the major open-source analysis tools.

Book excerpt: Our visual system can process information at both conscious and unconscious levels. Understanding the factors that control whether a stimulus reaches our awareness, and the fate of those stimuli that remain at an unconscious level, are the major challenges of brain science in the new millennium. Since its publication in 1984, Visual Masking has established itself as a classic text in the field of cognitive psychology. In the years since, there have been considerable advances in the cognitive neurosciences, and a growth of interest in the topic of consciousness, and the time is ripe for a new edition of this text. Where most current approaches to the study of visual consciousness adopt a 'steady-state' view, the approach presented in this book explores its dynamic properties. This new edition uses the technique of visual masking to explore temporal aspects of conscious and unconscious processes down to a resolution in the millisecond range. The 'time slices' through conscious and unconscious vision revealed by the visual masking technique can shed light on both normal and abnormal operations in the brain. The main focus of this book is on the microgenesis of visual form and pattern perception - microgenesis referring to the processes occurring in the visual system from the time of stimulus presentation on the retinae to the time, a few hundred milliseconds later, of its registration at conscious or unconscious perceptual and behavioural levels. The book takes a highly integrative approach by presenting microgenesis within a broad context encompassing visuo-temporal phenomena, attention, and consciousness.
