Spike-triggered fMRI in reading epilepsy: involvement of left frontal cortex working memory area.

OBJECTIVE: To determine the origin of epileptiform activity in reading epilepsy (RE) and the association between these regions and regions activated by reading, and to assess brain morphometry in these areas. METHODS: In two subjects with RE, EEG was ...

Separating distractor rejection and target detection in posterior parietal cortex--an event-related fMRI study of visual marking.

Successful survival in a competitive world requires the employment of efficient procedures for selecting new in preference to old information. Recent behavioral studies have shown that efficient selection is dependent not only on properties of new ...

Maintenance versus manipulation in verbal working memory revisited: an fMRI study.

Working memory (WM) is the ability to keep a limited amount of information "on line" for immediate use during short intervals. Verbal WM has been hypothesized to consist of neuroanatomically segregated components, i.e., maintenance (storage, rehearsal, ...

Practice-related effects demonstrate complementary roles of anterior cingulate and prefrontal cortices in attentional control.

The purpose of this study was to test the hypothesis that the dorsolateral prefrontal cortex (DLFPC), not the anterior cingulate cortex (ACC), plays the predominant role in implementing top-down attentional control. To do so, we used fMRI to examine ...

Modulation of a brain-behavior relationship in verbal working memory by rTMS.

We investigated whether the brain-behavior relationship (BBR) between regional cerebral blood flow (rCBF) as measured by positron emission tomography (PET) and individual accuracy in verbal working memory (WM) can be modulated by repetitive transcranial ...

Verbal free recall in high altitude: proper names vs common names.

Exposure to extreme altitude is known to cause a general impairment of cognitive functions. In this study we investigated the effect of high altitude on the recall of supraspan lists of proper and common names. High altitude seems to have a dramatic ...

Lorazepam and scopolamine: A single-dose comparison of effects on human memory and attentional processes.

This placebo-controlled, double-blind, double-dummy, independent groups study directly compared effects of the benzodiazepine, lorazepam (2.0 mg/70 kg orally administered), and the anticholinergic scopolamine (0.6 mg/70 kg subcutaneously administered) on ...

Audiospatial and visuospatial working memory in 6-13 year old school children.

The neural processes subserving working memory, and brain structures underlying this system, continue to develop during childhood. We investigated the effects of age and gender on audiospatial and visuospatial working memory in a nonclinical sample of ...

Dreaming and episodic memory: a functional dissociation?

The activity that takes place in memory systems during sleep is likely to be related to the role of sleep in memory consolidation and learning, as well as to the generation of dream hallucinations. This study addressed the often-stated hypothesis that ...

Testing a positional model of the Hebb effect.

In two experiments, we investigated the hypothesis that a strengthening of position-item associations underlies the improvement seen in performance on an immediate serial recall task, for a list that is surreptitiously repeated every third trial. Having ...
