Deformations in a Transverse Cross Section

Deformations in a Transverse Cross Section

When a material is subjected to uniaxial stress, it elongates or contracts in the direction of the applied force, and also undergoes changes in the perpendicular directions. This behavior is crucial for understanding how materials behave under stress and is governed by mechanical properties such as Poisson's ratio v, which measures the ratio of transverse strain to axial strain.
As the material stretches, it expands or contracts in orthogonal directions to the load. This phenomenon varies...

Somatosensation

Somatosensation

The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

Background:

Accurate mathematical models of the human brain's outer cortex are crucial for various neuroimaging applications.
Existing methods face challenges in representing complex cortical structures effectively.

Purpose of the Study:

To develop a robust mathematical representation of the human brain's outer cortex.
To enable advanced applications like morphological analysis and spatial normalization of brain images.

Main Methods:

A deformable surface algorithm is employed to parameterize the outer cortex by identifying the central layer of thick surfaces.
A hierarchical representation is generated using depth and multi-scale curvature maps.

Main Results:

The proposed parameterization effectively captures the outer cortical structure.
Experimental results on magnetic resonance data demonstrate the utility of the hierarchical representation.

Conclusions:

The developed method provides a valuable tool for quantitative analysis of brain morphology.
This approach enhances the accuracy and efficiency of brain image registration and normalization.
