Studies examining thought processes have focused upon the deliberate, goal-directed mental processes occurring during complex cognitive tasks. Spontaneously occurring thought processes have, on the other hand, received much less attention. Such spontaneous thought processes occur frequently when no task is present or when task demands are low. Although(More)
The anterior or rostrolateral prefrontal cortex (RLPFC) is frequently recruited during complex cognitive tasks across a wide range of domains, including reasoning, long-term memory retrieval, and working memory. The authors report an event-related functional MRI study, indicating that the RLPFC is specifically involved in the evaluation of internally(More)
PURPOSE The purpose of this study was to assess the feasibility of zoomed echo-planar imaging (EPI) diffusion tensor imaging (DTI) with 2-channel parallel transmission (pTx) for MR tractography of the periprostatic neurovascular bundle (NVB) without an endorectal coil, and to compare its performance to that of conventionally acquired DTI.

FPC function is restricted to the processing of simple cognitive branching, whereby only a single task can be maintained in a pending state at any one time. This hypothesis places severe serial and recursive constraints on human reasoning , problem-solving, and complex decision-making. Consistent with this view, it appears unlikely that the human brain has(More)
We examined the impact of explicit contamination on age-related changes in episodic priming. We recorded event-related brain potentials (ERPs) from older and younger adults to primed and unprimed nouns tested in a recognition memory task. Results revealed that the magnitude of priming was greater in the younger adults. ERPs revealed a priming effect in the(More)
