Functional neuroimaging options for tinnitus

Background: The pathophysiology behind tinnitus is still not well understood. Different imaging methods help in the understanding of the complex relationships that lead to the perception of tinnitus.Objective: Herein, different functional imaging methods that can be used in the study of tinnitus are presented.Materials and methods: Considering the recent literature on the subject, the relevant imaging methods used in tinnitus research are discussed.Results and conclusion: Functional imaging can reveal correlates of tinnitus. Due to the still limited temporal and spatial resolution of current imaging modalities, a conclusive explanation of tinnitus remains elusive. With increasing use of functional imaging, additional important insights into the explanation of tinnitus will be gained in the future.

Brain's Dynamic Functional Organization with Simultaneous EEG-fMRI Networks

João Pedro Forjaco Jorge, Patricia Figueiredo

The brain's functional networks can be assessed using imaging techniques like functional magnetic resonance imaging (fMRI) and electroencephalography (EEG). Recent studies have suggested a link between the dynamic functional connectivity (dFC) captured by ...

Limagerie cérébrale (dite aussi neuro-imagerie) désigne l'ensemble des techniques issues de l' qui permettent d'observer le cerveau, en particulier lorsqu'un individu exécute une tâche cognitive. L'observation du cerveau par autopsie est imprécise et incomplète en ce qu'elle se limite à l'analyse d'un état figé qui ne peut rendre compte d'effets liés aux évolutions dans l'organe vivant. Le premier effort connu de neuro-imagerie visant à dépasser cette limite a été la « balance de circulation humaine » de Angelo Mosso développée dans les années 1880.

Functional neuroimaging is the use of neuroimaging technology to measure an aspect of brain function, often with a view to understanding the relationship between activity in certain brain areas and specific mental functions. It is primarily used as a research tool in cognitive neuroscience, cognitive psychology, neuropsychology, and social neuroscience.

L'imagerie médicale regroupe les moyens d'acquisition et de restitution d'images du corps humain à partir de différents phénomènes physiques tels que l'absorption des rayons X, la résonance magnétique nucléaire, la réflexion d'ondes ultrasons ou la radioactivité auxquels on associe parfois les techniques d'imagerie optique comme l'endoscopie. Apparues, pour les plus anciennes, au tournant du , ces techniques ont révolutionné la médecine grâce au progrès de l'informatique en permettant de visualiser indirectement l'anatomie, la physiologie ou le métabolisme du corps humain.
