    Authors: Michel, Christoph;

    High-resolution EEG recording has become standard in many experimental studies on human brain function and has found its place in the routine presurgical workup of patients with focal epilepsy in several clinical centers. The main aim of high-resolution EEG is source localization with methods that have become increasingly robust and precise. However, high-resolution EEG also allows a spatial analysis of EEG and evoked potentials on the scalp level, thereby identifying topographic features of the scalp potential field. Their value in understanding the dynamics of large-scale networks of the human brain and as markers for neuropsychiatric diseases has been increasingly demonstrated. This chapter discusses the advantages and limitations of such spatial analysis methods and the information that can be gained from them. It also shows that the spatial frequency of the scalp potential field is higher than previously assumed and discusses the consequences regarding the number of channels required to properly capture these spatial frequencies.

    Nanobodies are considered as very promising antigen-binding moieties for molecular imaging and therapeutic purposes due to their favorable pharmacological and pharmacokinetic properties. However, the possibility for monovalent Nanobodies to reach targets in the central nervous system (CNS) remains to be demonstrated. We have assessed the blood-brain barrier permeability for Nb_An33, a Nanobody against the Trypanosoma brucei Variant-specific Surface Glycoprotein (VSG), in healthy rats and rats that are in the encephalitic stage of African trypanosomiasis and suffer from acute brain inflammation using intracerebral microdialysis, SPECT (Single Photon Emission Computed Tomography) or a combination of both methodologies. This enabled the quantification of unlabeled and (99m)Tc-labeled Nanobodies using respectively a sensitive VSG-based Nb-detection ELISA, radioactivity measurement in collected microdialysates and SPECT image analysis. The combined read-out methodologies demonstrate that, while brain disposition of Nb_An33 upon intravenous injection is at the limit of detection in healthy rats, inflammation-induced damage to the blood-brain barrier significantly increases (approximately 20 times) the Nanobody perfusion efficiency. Collectively, we illustrate the advantage of complementing SPECT analyses with intracerebral microdialysis in brain disposition studies and suggest that it is of interest to evaluate the blood-brain barrier penetrating potential of monovalent Nanobodies in models of CNS-inflammation. However, the pharmacokinetic properties that are considered favorable for peripheral imaging and therapeutic approaches might be key factors that preclude efficient application of Nanobodies to target the CNS.

    Authors: Michel, Christoph; He, Bin;

    Since the discovery of electroencephalography (EEG), when it was hoped that EEG would offer "a window into the brain," researchers and clinicians have attempted to localize the neuronal activity in the brain that generates the scalp potentials measured noninvasively with EEG. Early explorations in the 1950s using electric field theory to infer the location and orientation of the current dipole in the brain from the scalp potential distribution triggered considerable efforts to quantitatively deduce these sources. Initially, dipole fitting, or dipole localization, was the method of choice and many studies used this approach in experimental and clinical studies with remarkable success. Later on, new methods were proposed that attempted to overcome the problem of having to fix the number of sources a priori; these methods are known as distributed source imaging techniques. The introduction and increasing availability of magnetic resonance imaging, allowing detailed realistic anatomy of the brain and head to be incorporated in source localization methods, has drastically increased the precision of such approaches. Today, source localization of EEG (and magnetoencephalography, or MEG) has reached a level of consistency and precision that allows these methods to be placed in the family of brain imaging techniques. The particular advantage that they have over other imaging methods is their high temporal resolution, which allows the origin of activity to be distinguished from its propagation and information flow in large-scale brain networks to be examined. This chapter gives an overview of these methods and illustrates them with several examples, thereby focusing on EEG source imaging in epilepsy and presurgical planning, as clinical applications with remarkable maturation.

    | openaire: EC/H2020/810377/EU//ConnectToBrain Therapeutic non-invasive transcranial brain stimulation with previous treatment protocols showed at best moderate effect sizes and large interindividual variability with a substantial proportion of non-responders. A currently intensively discussed approach to address these problems is individualized closed-loop stimulation. ConnectToBrain is a synergy project funded by the European Research Council to develop noninvasive closed-loop therapeutic stimulation of network disorders of the human brain. It consists of three main pillars: (1) development of a multichannel transcranial magnetic stimulation (mTMS) coil array that covers nearly all of the cerebral cortex and enables highly precise electronic control of location, direction, intensity and timing of the induced electrical fields, (2) development of real-time analysis of activity and connectivity in brain networks using electroencephalography (EEG) for instantaneous spatial and temporal control of stimulation (brain state-dependent, closed-loop stimulation)and adaptive optimization of treatment effects by machine learning and (3) translation of these neurotechnological innovations into physiological and clinical studies.

    Authors: Gjedde, Albert Hellmut;

    Udgivelsesdato: 2003-null Blood-brain transfer of oxygen is a fundamental function of regional oxygen consumption. This function yielded a novel description of the mechanism of flow-metabolism coupling. The description revealed that constant oxygen consumption is not maintained by saturation of cytochrome oxidase but by adjustment of the enzyme's affinity towards oxygen. Interactions of oxygen and a factor that could be nitric oxide, at both cytochrome oxidase and nitric oxide synthase, match the affinities of both enzymes towards their respective substrates to the oxygen requirement of the tissue and, in doing so, explain several properties of flow-metabolism coupling.

    BACKGROUND: The NF-κB signaling pathway orchestrates many of the intricate aspects of neuroinflammation. Astrocytic β₂-adrenergic receptors have emerged as potential regulators in central nervous system inflammation and are potential targets for pharmacological modulation. The aim of this study was to elucidate the crosstalk between astrocytic β₂-adrenergic receptors and the TNF-α induced inflammatory gene program. METHODS: Proinflammatory conditions were generated by the administration of TNF-α. Genes that are susceptible to astrocytic crosstalk between β₂-adrenergic receptors (stimulated by clenbuterol) and TNF-α were identified by qPCR-macroarray-based gene expression analysis in a human 1321 N1 astrocytoma cell line. Transcriptional patterns of the identified genes in vitro were validated by RT-PCR on the 1321 N1 cell line as well as on primary rat astrocytes. In vivo expression patterns were examined by intracerebroventricular administration of clenbuterol and/or TNF-α in rats. To examine the impact on the inflammatory cell content of the brain we performed extensive FACS analysis of rat brain immune cells after intracerebroventricular clenbuterol and/or TNF-α administration. RESULTS: Parallel transcriptional patterns in vivo and in vitro confirmed the relevance of astrocytic β₂-adrenergic receptors as modulators of brain inflammatory responses. Importantly, we observed pronounced effects of β2-adrenergic receptor agonists and TNF-α on IL-6, CXCL2, CXCL3, VCAM1, and ICAM1 expression, suggesting a role in inflammatory brain cell homeostasis. Extensive FACS-analysis of inflammatory cell content in the brain demonstrated that clenbuterol/TNF-α co-administration skewed the T cell population towards a double negative phenotype and induced a shift in the myeloid brain cell population towards a neutrophilic predominance. CONCLUSIONS: Our results show that astrocytic β₂-adrenergic receptors are potent regulators of astrocytic TNF-α-activated genes in vitro and in vivo, and ultimately modulate the molecular network involved in the homeostasis of inflammatory cells in the central nervous system. Astrocytic β₂-adrenergic receptors and their downstream signaling pathway may serve as potential targets to modulate neuroinflammatory responses.

  • Authors: Vidal, Clement;

    This work is a critical analysis of the fascinating analogy between the brain and Internet. The aim is to examine how this analogy can be a powerful heuristic, for different purposes. We start with a quantitative and structural point of view, with the comparison of the web, the physical internet and the brain [1]. The second part [2] study more specifically the two ways of the analogy. From the brain to Internet [2.2], to see how the study of the brain could give us new ideas to develop the future of Internet. And from Internet to the brain [2.3], to examine how studies about the Internet could help the development of cognitive science. A controversial (because pre-scientific) hypothesis is proposed from this analogy [2.3.2]. The last part [3] takes the analogy in a broader sense, as an utopia to approach the future of society. Questions about the status of this "global brain" as a major transition of evolution, and about its consciousness are briefly discussed.

    Intraoperative neuromonitoring is a perioperative method, supplementary to stealth navigation and fluorescence microscopic imaging in brain surgery. It allows cortical and subcortical mapping, hence real time identification of eloquent brain areas through electrical stimulation of the cerebral cortex and subcortical areas. The method allows for functional guidance during both awake and asleep neurosurgery and aids in optimizing the extent of resection of the relevant pathology while preserving neurological function as summarised in this review.

    Authors: Michel, Christoph;

    High-resolution EEG recording has become standard in many experimental studies on human brain function and has found its place in the routine presurgical workup of patients with focal epilepsy in several clinical centers. The main aim of high-resolution EEG is source localization with methods that have become increasingly robust and precise. However, high-resolution EEG also allows a spatial analysis of EEG and evoked potentials on the scalp level, thereby identifying topographic features of the scalp potential field. Their value in understanding the dynamics of large-scale networks of the human brain and as markers for neuropsychiatric diseases has been increasingly demonstrated. This chapter discusses the advantages and limitations of such spatial analysis methods and the information that can be gained from them. It also shows that the spatial frequency of the scalp potential field is higher than previously assumed and discusses the consequences regarding the number of channels required to properly capture these spatial frequencies.

    Nanobodies are considered as very promising antigen-binding moieties for molecular imaging and therapeutic purposes due to their favorable pharmacological and pharmacokinetic properties. However, the possibility for monovalent Nanobodies to reach targets in the central nervous system (CNS) remains to be demonstrated. We have assessed the blood-brain barrier permeability for Nb_An33, a Nanobody against the Trypanosoma brucei Variant-specific Surface Glycoprotein (VSG), in healthy rats and rats that are in the encephalitic stage of African trypanosomiasis and suffer from acute brain inflammation using intracerebral microdialysis, SPECT (Single Photon Emission Computed Tomography) or a combination of both methodologies. This enabled the quantification of unlabeled and (99m)Tc-labeled Nanobodies using respectively a sensitive VSG-based Nb-detection ELISA, radioactivity measurement in collected microdialysates and SPECT image analysis. The combined read-out methodologies demonstrate that, while brain disposition of Nb_An33 upon intravenous injection is at the limit of detection in healthy rats, inflammation-induced damage to the blood-brain barrier significantly increases (approximately 20 times) the Nanobody perfusion efficiency. Collectively, we illustrate the advantage of complementing SPECT analyses with intracerebral microdialysis in brain disposition studies and suggest that it is of interest to evaluate the blood-brain barrier penetrating potential of monovalent Nanobodies in models of CNS-inflammation. However, the pharmacokinetic properties that are considered favorable for peripheral imaging and therapeutic approaches might be key factors that preclude efficient application of Nanobodies to target the CNS.

    Authors: Michel, Christoph; He, Bin;

    Since the discovery of electroencephalography (EEG), when it was hoped that EEG would offer "a window into the brain," researchers and clinicians have attempted to localize the neuronal activity in the brain that generates the scalp potentials measured noninvasively with EEG. Early explorations in the 1950s using electric field theory to infer the location and orientation of the current dipole in the brain from the scalp potential distribution triggered considerable efforts to quantitatively deduce these sources. Initially, dipole fitting, or dipole localization, was the method of choice and many studies used this approach in experimental and clinical studies with remarkable success. Later on, new methods were proposed that attempted to overcome the problem of having to fix the number of sources a priori; these methods are known as distributed source imaging techniques. The introduction and increasing availability of magnetic resonance imaging, allowing detailed realistic anatomy of the brain and head to be incorporated in source localization methods, has drastically increased the precision of such approaches. Today, source localization of EEG (and magnetoencephalography, or MEG) has reached a level of consistency and precision that allows these methods to be placed in the family of brain imaging techniques. The particular advantage that they have over other imaging methods is their high temporal resolution, which allows the origin of activity to be distinguished from its propagation and information flow in large-scale brain networks to be examined. This chapter gives an overview of these methods and illustrates them with several examples, thereby focusing on EEG source imaging in epilepsy and presurgical planning, as clinical applications with remarkable maturation.

    | openaire: EC/H2020/810377/EU//ConnectToBrain Therapeutic non-invasive transcranial brain stimulation with previous treatment protocols showed at best moderate effect sizes and large interindividual variability with a substantial proportion of non-responders. A currently intensively discussed approach to address these problems is individualized closed-loop stimulation. ConnectToBrain is a synergy project funded by the European Research Council to develop noninvasive closed-loop therapeutic stimulation of network disorders of the human brain. It consists of three main pillars: (1) development of a multichannel transcranial magnetic stimulation (mTMS) coil array that covers nearly all of the cerebral cortex and enables highly precise electronic control of location, direction, intensity and timing of the induced electrical fields, (2) development of real-time analysis of activity and connectivity in brain networks using electroencephalography (EEG) for instantaneous spatial and temporal control of stimulation (brain state-dependent, closed-loop stimulation)and adaptive optimization of treatment effects by machine learning and (3) translation of these neurotechnological innovations into physiological and clinical studies.

    Authors: Gjedde, Albert Hellmut;

    Udgivelsesdato: 2003-null Blood-brain transfer of oxygen is a fundamental function of regional oxygen consumption. This function yielded a novel description of the mechanism of flow-metabolism coupling. The description revealed that constant oxygen consumption is not maintained by saturation of cytochrome oxidase but by adjustment of the enzyme's affinity towards oxygen. Interactions of oxygen and a factor that could be nitric oxide, at both cytochrome oxidase and nitric oxide synthase, match the affinities of both enzymes towards their respective substrates to the oxygen requirement of the tissue and, in doing so, explain several properties of flow-metabolism coupling.
