Functional Brain Activity within the Medial and Lateral Portion of BA10 during a Prospective Memory Task
نویسندگان
چکیده
In this study we tested the gateway hypothesis of Broadmann area 10 (BA10). With a functional magnetic resonance imaging (fMRI) protocol we manipulated the saliency--stimulus-oriented (SO) attending--and the memory load--stimulus-independent (SI) attending--during a prospective memory (PM) task. We found a significant main effect of the SO manipulation within the medial BA10 and a significant interaction between SI attending and PM task within the left lateral BA10. Our results give experimental support to the gateway hypothesis.

Functional interplay between stimulus-oriented and stimulus-independent attending during a prospective memory task.
Recent studies have suggested that medial (medBA10) and lateral (latBA10) portions of the Brodmann area 10 subserve respectively stimulus-oriented (SO) and stimulus-independent (SI) attending during prospective memory (PM) tasks. We investigated this dissociation by manipulating the saliency (SO) and the memory load (SI) of PM cues. Sixteen healthy subjects participated to a functional imaging ...
متن کاملLocalizing the rostrolateral prefrontal cortex at the individual level.
The functions of the rostrolateral prefrontal cortex (RLPFC) have recently become the target of multiple theories and empirical investigations. This region can be loosely defined as the lateral portion of Brodmann area (BA) 10. One of the challenges in testing theories about RLPFC functions is the difficulty in defining its boundaries when formulating predictions for its recruitment. Here we pr...
متن کاملAcute effects of nicotine administration during prospective memory, an event related fMRI study.
We previously demonstrated that stimulating neuronal nicotinic acetylcholine receptors modulates prospective memory (PM), the ability to remember and implement a prior intention. Here we used fMRI to explore the neuronal correlates of acute nicotinic (1mg) modulation during PM, employing a double blind, valence-matched placebo-controlled design, and a solely event-related analysis. Eight health...
متن کاملAssessment of Prospective Memory using fNIRS in Immersive Virtual Reality Environment
In order to measure real life prospective memory (PM) ability in laboratory setting, previous studies have used photograph-based, video-based and virtual reality (VR)-based to simulate real life environment. In this study, we used the Functional Near-Infrared Spectroscopy (fNIRS) to record participants’ brain activities when they are performing PM tasks in immersive VR environment. 10 participa...

New studies in neuromuscular control have indicated that the strength of muscle contraction isn’t the only important factor in a task. But the speed at which a muscle responds, preparation of muscle and synergistic pattern at which a group of muscles recruit to a task or respond to a condition are much more important in constant joint stabilization and potential injury prevention. The purpo...
