Role of left inferior prefrontal cortex in retrieval of semantic knowledge: a reevaluation.
A number of neuroimaging findings have been interpreted as evidence that the left inferior frontal gyrus (IFG) subserves retrieval of semantic knowledge. We provide a fundamentally differentExpand

Functional Magnetic Resonance Imaging Evidence for a Hierarchical Organization of the Prefrontal Cortex
TLDR
We test whether the rostro-caudal axis of the PFC is organized hierarchically, based on the level of abstraction at which multiple representations compete to guide selection of action. Expand

Age-related top-down suppression deficit in the early stages of cortical visual memory processing
In this study, electroencephalography (EEG) was used to examine the relationship between two leading hypotheses of cognitive aging, the inhibitory deficit and the processing speed hypothesis. We showExpand

The roles of prefrontal brain regions in components of working memory: effects of memory load and individual differences.
Using an event-related functional MRI design, we explored the relative roles of dorsal and ventral prefrontal cortex (PFC) regions during specific components (Encoding, Delay, Response) of a workingExpand

fMRI evidence of age-related hippocampal dysfunction in feature binding in working memory.
Richly detailed memories for particular events depend on processes that bind individual features of experience together. Previous cognitive behavioral research indicates that older adults have moreExpand

The modular and integrative functional architecture of the human brain
TLDR
We investigate the modular functional architecture of the human brain by analyzing activity at different types of nodes in the network across 9,208 experiments of 77 cognitive tasks in the BrainMap database. Expand

Impulsive responding in alcoholics.
BACKGROUND Impaired decision-making is one diagnostic characteristic of alcoholism. Quantifying decision-making with rapid and robust laboratory-based measures is thus desirable for the testing ofExpand

Success and Failure Suppressing Reflexive Behavior
The dynamic interplay between reflexive and controlled determinants of behavior is one of the most general organizing principles of brain function. A powerful analogue of this interplay is seen inExpand

The Search for the Phonological Store: From Loop to Convolution
TLDR
The phonological loop system of Baddeley and colleagues' Working Memory model is a major accomplishment of the modern era of cognitive psychology. Expand

The neural substrate and temporal dynamics of interference effects in working memory as revealed by event-related functional MRI.
TLDR
We identify temporally and temporally the neural correlates of processes contributing to the target presentation, delay, and probe portions of an item-recognition task. Expand
