Correlation between and due to listening to artificial languages Correlation between cortical thickness and brain activation due to listening to artificial languages DBP 1 fMRI task designed to tap word segmentation ability applied to 12 normal kids (9 – 11 y/o). fMRI task designed to tap word segmentation ability applied to 12 normal kids (9 – 11 y/o). Results support the hypothesis that the less mature brain may recruit both hemispheres when faced with learning a novel language.

Brain changes automatically detected in a semantic dementia patient DBP 2 % GM & CSF are computed relative to the initial MRI scan of the patient. % GM & CSF are computed relative to the initial MRI scan of the patient. The profile of disease progression is revealed. The profile of disease progression is revealed.

Multimodal registration of mouse brain data: Initial misfit (left) compared to final registration (right) Core1 Aim 1 A novel combined registration and segmentation algorithm is developed and applied to DBP 3 data. A novel combined registration and segmentation algorithm is developed and applied to DBP 3 data.

Left – Direct 3D-to-3D mapping; Right - harmonic map result Core1 Aim 1 Advantages over existing Surface mapping methods: Advantages over existing Surface mapping methods: Less distortion during the mapping process.Less distortion during the mapping process. Analysis of the mapping with intrinsic calculus made easy with implicit representations.Analysis of the mapping with intrinsic calculus made easy with implicit representations.
