Cortical mechanisms of human imitation.
How does imitation occur? How can the motor plans necessary for imitating an action derive from the observation of that action? Imitation may be based on a mechanism directly matching the observedExpand

Rapid Automated Algorithm for Aligning and Reslicing PET Images
A computer algorithm for the three-dimensional (3D) alignment of PET images is described. To align two images, the algorithm calculates the ratio of one image to the other on a voxel-by-voxel basisExpand

Automated image registration: I. General methods and intrasubject, intramodality validation.
PURPOSE We sought to describe and validate an automated image registration method (AIR 3.0) based on matching of voxel intensities. METHOD Different cost functions, different minimization methods,Expand

MRI‐PET Registration with Automated Algorithm
Objective We have previously reported an automated method for within-modality (e.g., PET-to-PET) image alignment. We now describe modifications to this method that allow for cross-modalityExpand

Enhancement of MR images using registration for signal averaging
Purpose: With the advent of noninvasive neuroimaging, a plethora of digital human neuroanatomical atlases has been developed. The accuracy of these atlases is constrained by the resolution andExpand

Area V5 of the human brain: evidence from a combined study using positron emission tomography and magnetic resonance imaging.
In pursuing our work on the organization of human visual cortex, we wanted to specify more accurately the position of the visual motion area (area V5) in relation to the sulcal and gyral pattern ofExpand

Mapping motor representations with positron emission tomography
BRAIN activity was mapped in normal subjects during passive obser-vation of the movements of an 'alien' hand and while imagining grasping objects with their own hand. None of the tasks requiredExpand
