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

Wandering Minds: The Default Network and Stimulus-Independent Thought
Despite evidence pointing to a ubiquitous tendency of human minds to wander, little is known about the neural operations that support this core component of human cognition. Using both thought… Expand

Dynamic reconfiguration of human brain networks during learning
Human learning is a complex phenomenon requiring flexibility to adapt existing brain function and precision in selecting new neurophysiological activities to drive desired behavior. These two… Expand

Automated image registration: II. Intersubject validation of linear and nonlinear models.
TLDR
PURPOSE Our goal was to validate linear and nonlinear intersubject image registration using an automated method (AIR 3.0) based on voxel intensity. Expand

Role of the posterior parietal cortex in updating reaching movements to a visual target
The exact role of posterior parietal cortex (PPC) in visually directed reaching is unknown. We propose that, by building an internal representation of instantaneous hand location, PPC computes a… Expand

Forward modeling allows feedback control for fast reaching movements
Delays in sensorimotor loops have led to the proposal that reaching movements are primarily under pre-programmed control and that sensory feedback loops exert an influence only at the very end of a… Expand

Functional Mapping of Sequence Learning in Normal Humans
The brain localization of motor sequence learning was studied in normal subjects with positron emission tomography. Subjects performed a serial reaction time (SRT) task by responding to a series of… Expand

Localization of grasp representations in humans by positron emission tomography
Positron emission tomography imaging of cerebral blood flow was used to localize brain areas involved in the representation of hand grasping movements. Seven normal subjects were scanned under three… Expand

Response to Comment on "Wandering Minds: The Default Network and Stimulus-Independent Thought"
Gilbert et al. suggest that activity in the default network may be due to the emergence of stimulus-oriented rather than stimulus-independent thought. Although both kinds of thought likely emerge… Expand

Amygdala activity related to enhanced memory for pleasant and aversive stimuli
Pleasant or aversive events are better remembered than neutral events. Emotional enhancement of episodic memory has been linked to the amygdala in animal and neuropsychological studies. Using… Expand
