Common Blood Flow Changes across Visual Tasks: II. Decreases in Cerebral Cortex
Nine previous positron emission tomography (PET) studies of human visual information processing were reanalyzed to determine the consistency across experiments of blood flow decreases during active
Cerebellum and nonmotor function.
TLDR
Neuroimaging and neuropsychological data supply compelling support for the view that a closed-loop circuit represents the major architectural unit of cerebro-cerebellar interactions and provides the cerebellum with the anatomical substrate to influence the control of movement and cognition.
Practice-related changes in human brain functional anatomy during nonmotor learning.
TLDR
Examination of the functional anatomy of the human brain with positron emission tomography during the naive and practiced performance of a simple verbal response selection task indicates that two distinct circuits can be used forverbal response selection and normal subjects can change the brain circuits used during task performance following less than 15 min of practice.
Tracking the hemodynamic responses to reward and punishment in the striatum.
TLDR
An event-related functional magnetic resonance imaging paradigm is developed to identify brain areas that are activated after presentation of a reward and shows differential responses to reward and punishment.

TLDR
This review discusses how neuroimaging can contribute to the authors' understanding of a fundamental aspect of skilled reading: the ability to pronounce a visually presented word and highlights the importance of spelling-to-sound consistency in the transformation from orthographic (word form) to phonological (word sound) representations.
Phonology, semantics, and the role of the left inferior prefrontal cortex

TLDR
Herbster et al. (1997) contribute to the growing literature on the functional neuroanatomy of word reading by evaluating stimulus-specific activation differences and hypothesize that the left inferior frontal gyrus may be part of a phonological pathway which supportsword reading, whereas the fusiform gyrus has been implicated in semantic processing.
Neural correlates of recovery from aphasia after damage to left inferior frontal cortex
TLDR
Right-IFG activity may represent either the recruitment of a preexisting neural pathway through alternative behavioral strategies or an anomalous response caused by removal of the left IFG.
Prefrontal responses to drug cues: a neurocognitive analysis
TLDR
Using a framework drawn from behavioral research indicating that perceived drug use opportunity significantly affects responses to the presentation of drug cues provides a way to reconcile discrepant findings among brain-imaging studies of cue-elicited craving.
