Assessing the significance of focal activations using their spatial extent
TLDR
The results mean that detecting significant activations no longer depends on a fixed threshold, but can be effected at any (lower) threshold, in terms of the spatial extent of the activated region.
Cortical mechanisms of human imitation.
TLDR
Two areas with activation properties that become active during finger movement, regardless of how it is evoked, and their activation should increase when the same movement is elicited by the observation of an identical movement made by another individual are found.
Rapid Automated Algorithm for Aligning and Reslicing PET Images
TLDR
A computer algorithm for the three-dimensional alignment of PET images is described that relies on anatomic information in the images rather than on external fiducial markers and can be applied retrospectively, during acquisition, to reposition the scanner gantry and bed to match an earlier study.
Grasping the Intentions of Others with One's Own Mirror Neuron System
TLDR
Functional magnetic resonance imaging revealed that premotor mirror neuron areas—areas active during the execution and the observation of an action—previously thought to be involved only in action recognition are actually also involved in understanding the intentions of others.
Neural mechanisms of empathy in humans: A relay from neural systems for imitation to limbic areas
TLDR
There was greater activity during imitation, compared with observation of emotions, in premotor areas including the inferior frontal cortex, as well as in the superior temporal cortex, insula, and amygdala, which may be a critical relay from action representation to emotion.
Automated image registration: I. General methods and intrasubject, intramodality validation.
TLDR
The registration algorithm described is a robust and flexible tool that can be used to address a variety of image registration problems and can be tailored to meet different needs by optimizing tradeoffs between speed and accuracy.
MRI‐PET Registration with Automated Algorithm
TLDR
Modifications to this method that allow for cross-modality registration of MRI and PET brain images obtained from a single subject are described and validated quantitatively using data from patients with stereotaxic fiducial markers rigidly fixed in the skull.
Automated image registration: II. Intersubject validation of linear and nonlinear models.
TLDR
Linear or nonlinear automated intersubject registration based on voxel intensities is computationally practical and produces more accurate alignment of homologous landmarks than manual nine parameter Talairach registration.
A probabilistic atlas and reference system for the human brain: International Consortium for Brain Mapping (ICBM).
TLDR
The ability to quantify the variance of the human brain as a function of age in a large population of subjects for whom data is also available about their genetic composition and behaviour will allow for the first assessment of cerebral genotype-phenotype-behavioural correlations in humans to take place in a population this large.
Area V5 of the human brain: evidence from a combined study using positron emission tomography and magnetic resonance imaging.
TLDR
P positron emission tomography was used to determine the foci of relative cerebral blood flow increases produced when subjects viewed a moving checkerboard pattern, compared to viewing the same pattern when it was stationary.
