Cortical Surface Parameterization by P-Harmonic Energy Minimization
Cortical surface parameterization has several applications in visualization and analysis of the brain surface. Here we propose a scheme for parameterizing the surface of the cereb...

Solving for Motion and Activation Simultaneously in an fMRI Experiment with Multiple Stimulus Conditions
It has recently been shown that greater accuracy in fMRI processing can be achieved if registration and activation detection are solved simultaneously rather than in sequence. How...

Effect of minicolumnar disturbance on dyslexic brains: an MRI study
The minicolumn is generally considered the basic unit of the neocortex in all the mammalian brains. Enlargement of the cortical surface is believed to occur through the addition o...
