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 ofExpand

Explicit and Implicit Contributions to Learning in a Sensorimotor Adaptation Task
Visuomotor adaptation has been thought to be an implicit process that results when a sensory-prediction error signal is used to update a forward model. A striking feature of human competence is theExpand

Whorf hypothesis is supported in the right visual field but not the left.
The question of whether language affects perception has been debated largely on the basis of cross-language data, without considering the functional organization of the brain. The nature of thisExpand

Motor sequence learning with the nondominant left hand
Whereas the human right hemisphere is active during execution of contralateral hand movements, the left hemisphere is engaged for both contra- and ipsilateral movements, at least for right-handedExpand

Dedicated and intrinsic models of time perception
Two general frameworks have been articulated to describe how the passage of time is perceived. One emphasizes that the judgment of the duration of a stimulus depends on the operation of dedicatedExpand

Ipsilateral motor cortex activity during unimanual hand movements relates to task complexity.
Functional imaging studies have revealed recruitment of ipsilateral motor areas during the production of sequential unimanual finger movements. This phenomenon is more prominent in the leftExpand

Perception and production of temporal intervals across a range of durations: evidence for a common timing mechanism.
Study participants performed time perception and production tasks over a set of 4 intervals ranging from 325 to 550 ms. In 3 experiments, variability on both the production and perception tasks wasExpand

The representation of temporal information in perception and motor control
  • R. Ivry

  • Current Opinion in Neurobiology
  • 1 December 1996
The representation of temporal information can be examined from both a neurological and a computational perspective. Recent evidence suggests that two subcortical structures, the cerebellum and basalExpand

Dissociable contributions of the prefrontal and neocerebellar cortex to time perception.
We report a series a three psychophysical experiments designed to differentiate the contributions of the neocerebellar and prefrontal cortex to time perception. Comparison of patients with focal,Expand
