Hysteria, a mysterious disease known since antiquity, is said to have ceased to exist. Challenging this commonly held view, this is the first cross-disciplinary study to examine the current functional neuroimaging research into hysteria and compare it to the 19th-century image-based research into the same disorder. Paula Muhr's central argument is that, both in the 19th-century and current neurobiological research on hysteria, images have enabled researchers to generate new medical insights. Through detailed case studies, Muhr traces how different images, from photography to functional brain scans, have reshaped the historically situated medical understanding of this disorder that defies the mind-body dualism.

In this EBook, we highlight how newly emerging techniques for non-invasive manipulation of the human brain, combined with simultaneous recordings of neural activity, contribute to the understanding of brain functions and neural dynamics in humans. A growing body of evidence indicates that the neural dynamics (e.g., oscillations, synchrony) are important in mediating information processing and networking for various functions in the human brain. Most of previous studies on human brain dynamics, however, show correlative relationships between brain functions and patterns of neural dynamics measured by imaging methods such as electroencephalography (EEG), magnetoencephalography (MEG), near-infrared spectroscopy (NIRS), positron emission tomography (PET) and functional magnetic resonance imaging (fMRI). In contrast, manipulative approaches by non-invasive brain stimulation (NIBS) have been developed and extensively used. These approaches include transcranial magnetic stimulation (TMS) and transcranial electric stimulation (tES) such as transcranial direct current stimulation (tDCS), alternating current stimulation (tACS), and random noise stimulation (tRNS), which can directly manipulate neural dynamics in the intact human brain. Although the neural-correlate approach is a strong tool, we think that manipulative approaches have far greater potential to show causal roles of neural dynamics in human brain functions. There have been technical challenges with using manipulative methods together with imaging methods. However, thanks to recent technical developments, it has become possible to use combined methods such as TMS–EEG coregistration. We can now directly measure and manipulate neural dynamics and analyze functional consequences to show causal roles of neural dynamics in various brain functions. Moreover, these combined methods can probe brain excitability, plasticity and cortical networking associated with information processing in the intact human brain. The contributors to this EBook have succeeded in showcasing cutting-edge studies and demonstrate the huge impact of their approaches on many areas in human neuroscience and clinical applications.

Ces dernières années, les techniques d’exploration par imagerie sont devenues incontournables dans le domaine de la recherche en neurosciences. Cette technique a l’avantage d’être non-invasive et de permettre l’identification de zones cérébrales en fonctionnement. L’identification des modifications cérébrales liées aux effets d’une thérapie pourrait être utile pour comprendre quels mécanismes cognitifs sont à l’œuvre et quelles thérapies sont les plus pertinentes pour un profil donné. En ce qui concerne l’aphasie, celle-ci est caractérisée par des problèmes d’accès aux représentations langagières, mais également par des problèmes de manipulation de ces représentations maintenues en mémoire (Hamilton & R.C. Martin, 2007). Il semblerait que ces déficits en mémoire à court terme soient dus à un déficit d’inhibition au niveau sémantique (Hamilton & R. C. Martin, 2005 ; Jefferies, Hoffman, Jones & Ralph, 2007). En suivant la trajectoire de Carnol (2010), Wannenmacher (2013) et Burgholzer (2017), nous avons donc évalué l’efficacité d’une technique de rééducation ciblée sur le contrôle sémantique (Van der Kaa et al., en préparation) développée au Centre Hospitalier Universitaire de Liège. L’objectif était d’améliorer les performances en mémoire à court terme verbale d’un patient aphasique. Nous résultats aux épreuves cliniques ne démontrent pas d’amélioration nette en ce qui concerne les performances en mémoire à court terme verbale mais des améliorations sont observées grâce aux tâches IRMf pour le contrôle sémantique. En parallèle d’une amélioration des performances du patient, nous observons une normalisation des activations cérébrales par rapport à celles de sujets normaux également recrutés dans l’étude. Cependant, il reste difficile de conclure quant à la spécificité du mécanisme de contrôle. Au vu des résultats obtenus par Burgholzer (2017) et ceux obtenus ici, il semble pertinent de continuer la recherche pour obtenir plus d’informations concernant l’effet de l’entrainement du contrôle langagier sur les performances des patients et les activations cérébrales liées aux changements comportementaux observés.
