High-resolution EEG mapping of cortical activation related to working memory: effects of task difficulty, type of processing, and practice.
The results serve to dissociate the effects of task difficulty and practice, to differentiate the involvement of posterior cortex in spatial versus verbal tasks, to localize frontal midline theta to the anteromedial cortex, and to demonstrate the feasibility of using anatomical MRIs to remove the blurring effect of the skull and scalp from the ongoing EEG.

Neurophysiological measures of working memory and individual differences in cognitive ability and cognitive style.
Electroencephalograms recorded from 80 healthy young adults during spatial working memory tasks indicated that high-ability subjects developed strategies that made relatively greater use of parietal regions, whereas low-ability Subjects relied more exclusively on frontal regions, and hemispheric asymmetries in alpha band measures distinguish between individuals with relatively high verbal aptitude and those with relatively low nonverbal aptitude.

Neurophysiological signals of working memory in normal aging.
To examine how neurophysiological signals of working memory (WM) change with normal aging, we recorded EEGs from healthy groups (n=10 each) of young (mean age=21 years), middle-aged (mean=47 years),Expand
Neurophysiological indices of strategy development and skill acquisition.
The results suggest that the EEG can be used to monitor practice-related changes in the patterns of cortical activity that are associated with task processing, and suggest that cortical regions not necessary for task performance become less active as skills develop. Expand
Dynamic cortical networks of verbal and spatial working memory: effects of memory load and task practice.
A millisecond timescale view of the activity induced in distributed cortical networks by tasks that impose significant WM demands suggests that WM emerges from the formation of a dynamic cortical network linking task-specific processes with non-specific, capacity-limited, higher-order attentional processes.

Human medial temporal lobe potentials evoked in memory and language tasks.
Evoked potentials recorded from the MTL during verbal recognition memory display two late endogenous components, one of which might be involved with memory formation and retrieval processes, and the other might index completion of the detection-recognition cycle. Expand
The intracranial topography of the P3 event-related potential elicited during auditory oddball.
In order to isolate the anatomical locus of neural activity primarily responsible for generating the scalp-recorded P3 (or P300), the topography of event-related potentials (ERPs) elicited during anExpand

The lack of a repetition-induced ERP difference after left-ATL reported here provides converging evidence for a critical role of the temporal lobe in contextual retrieval during recognition. Expand
Test–retest reliability of cognitive EEG
Under appropriate conditions, task-related EEG has sufficient retest reliability for use in assessing clinical changes in cognitive status, and is suggested to have high test-retest reliability within and between sessions. Expand
