Event-Related fMRI: Characterizing Differential Responses
TLDR
This paper focuses on bilateral ventrolateral prefrontal responses that show deactivations for previously seen words and activations for novel words in functional magnetic resonance imaging that are evoked by different sorts of stimuli. Expand
Stop-signal inhibition disrupted by damage to right inferior frontal gyrus in humans
TLDR
This work uses a new observer-independent method to relate the degree of damage within a specific prefrontal region to performance on a stop-signal task that is sensitive to the neurodevelopmental aspects of stopping behavior and to attention-deficit/hyperactivity disorder (ADHD) as well as its amelioration by methylphenidate. Expand
Reading the mind in cartoons and stories: an fMRI study of ‘theory of mind’ in verbal and nonverbal tasks
TLDR
Brain activation during the theory of mind condition of a story task and a cartoon task showed considerable overlap in the medial prefrontal cortex (paracingulate cortex), which is discussed in relation to the cognitive mechanisms underpinning the authors' everyday ability to 'mind-read'. Expand
Other minds in the brain: a functional imaging study of “theory of mind” in story comprehension
TLDR
The localisation of brain regions involved in normal attribution of mental states and contextual problem solving is feasible and may have implication for the neural basis of autism. Expand
Frontal lobes and human memory: insights from functional neuroimaging.
TLDR
It is predicted that the resolution of questions concerning the functional neuroanatomical subdivisions of the frontal cortex will ultimately depend on a fuller cognitive psychological fractionation of memory control processes, an enterprise that will be guided and tested by experimentation. Expand
Brain regions associated with acquisition and retrieval of verbal episodic memory
TLDR
The results provide clear evidence that episodic memory involves a network of specific prefrontal and posterior structures which can be fractionated into different component processes. Expand
Changing Human Behavior to Prevent Disease: The Importance of Targeting Automatic Processes
TLDR
It is proposed that interventions targeting these automatic bases of behaviors may be more effective and ways to determine whether and how interventions that target automatic processes can enhance global efforts to prevent disease are suggested. Expand
Sense of agency in health and disease: A review of cue integration approaches☆
TLDR
The relevance to SoA of a novel Bayesian cue integration framework is considered and the value of this framework in understanding SoA in health and disease is discussed. Expand
Regional brain activity in chronic schizophrenic patients during the performance of a verbal fluency task.
TLDR
Chronic schizophrenic patients can show a normal magnitude of frontal activation when matched for performance with controls, and they fail to show the expected reductions of activity in the superior temporal cortex, suggesting abnormal functional connectivity between frontal and temporal cortex. Expand
Guidelines for reporting an fMRI study
TLDR
A set of guidelines for the reporting of methods and results in functional magnetic resonance imaging studies are outlined and a checklist to assist authors in preparing manuscripts that meet these guidelines are provided. Expand
