Le concept de « cerveau standardisé » est familier dans les techniques modernes de neuro-imagerie fonctionnelle, notamment la TEP et l'IRMf, mais il n'a jamais été adopté pour les études d'imagerie optique portant sur une zone corticale régionale plutôt que sur l'ensemble du cerveau. Dans cet article, nous proposons un « cortex baril standardisé » pour les rongeurs et présentons une méthode de cartographie de l’activité neuronale détectée optiquement sur le cortex standard. Le cortex standard est défini comme un ensemble de colonnes corticales simples, modélisées sur les modèles cytoarchitectoniques des agrégats cellulaires de la couche corticale IV du cortex en tonneau. En se référant à sa structure anatomique sous-jacente, la méthode déforme l’image de surface des cortex individuels pour l’adapter au cortex standard. Le cortex est déformé à l’aide d’une technique de déformation de forme libre bidimensionnelle avec manipulation directe. Puisque l’imagerie optique fournit une carte de l’activité neuronale sur la surface corticale, la déformation la remappe par conséquent sur le cortex standard. Les données présentées dans cet article montrent que l'activité neuronale évoquée somatosensorielle est représentée avec succès sur le cortex standardisé, ce qui suggère que la combinaison de l'imagerie optique avec notre méthode constitue une approche prometteuse pour étudier l'architecture fonctionnelle du cortex.

Abstract: The concept of a "standardized brain" is familiar in modern functional neuro-imaging techniques including PET and fMRI, but it has never been adopted for optical imaging studies that deal with a regional cortical area rather than the whole brain. In this paper, we propose a "standardized barrel cortex" for rodents, and present a method for mapping optically detected neural activity onto the standard cortex. The standard cortex is defined as a set of simple cortical columns, which are modeled on the cytoarchitectonic patterns of cell aggregates in cortical layer IV of the barrel cortex. Referring to its underlying anatomical structure, the method warps the surface image of individual cortices to fit the standard cortex. The cortex is warped using a two-dimensional free-form deformation technique with direct manipulation. Since optical imaging provides a map of neural activity on the cortical surface, the warping consequently remaps it on the standard cortex. Data presented in this paper show that somatosensory evoked neural activity is successfully represented on the standardized cortex, suggesting that the combination of optical imaging with our method is a promising approach for investigating the functional architecture of the cortex.
