[A 3T fMRI study of cortical projection of visual scotomas: preliminary results].

Aim: We used functional magnetic resonance imaging (fMRI) to precisely measure both the localization and size of the cortical projections of artificial scotomas in healthy subjects as well as the size of a reversible retinal scotoma in a patient with central serous chorioretinopathy (CSCR).

Methods: Using a 3T MRI scanner, anatomical and functional data were acquired on two healthy subjects and a patient with CSCR. Retinotopic maps were first reconstructed using phase mapping techniques.

[Retinotopic organization of the human visual cortex: a 3T fMRI study].

Unlabelled: INTRODUCTION. We used high-field (3T) functional magnetic resonance imaging (fMRI) to map the retinotopic organization of human cortical areas.

Methods: Retinotopic maps were reconstructed using existing mapping techniques.

Variational, geometric, and statistical methods for modeling brain anatomy and function.

We survey the recent activities of the Odyssée Laboratory in the area of the application of mathematics to the design of models for studying brain anatomy and function. We start with the problem of reconstructing sources in MEG and EEG, and discuss the variational approach we have developed for solving these inverse problems. This motivates the need for geometric models of the head.
