Ullsperger P, Freude G, Erdmann U
Int J Psychophysiol
. 2001 Mar;
40(3):201-9.
PMID: 11228347
The goal of this study was to explore the utility of parameters of ERPs for assessment of mental workload during performance of complex tasks. In addition to a baseline auditory...

Neuroreport
. 2000 Jul;
11(9):1861-4.
PMID: 10884033
The event-related potentials (ERPs) to the stimuli triggered by a participant's self-paced key press were compared with the ERPs to the same stimuli presented at an external pace. Fourteen participants...

NITTONO H, Nageishi Y, Nakajima Y, Ullsperger P
Psychophysiology
. 1999 Nov;
36(6):745-54.
PMID: 10554588
The capacity of working memory has been suggested to differ among people and these differences affect performance in a wide variety of cognitive tasks. This study explored electrophysiological correlates of...

Freude G, Ullsperger P, Eggert S, Ruppe I
Eur J Appl Physiol
. 1999 Nov;
81(1-2):18-27.
PMID: 10552262
The influence of electromagnetic fields (EMF) emitted by cellular telephones on preparatory slow brain potentials (SP) was studied in two experiments, about 6 months apart. In the first experiment, a...

Freude G, Ullsperger P, Erdmann U
Int J Psychophysiol
. 1999 Oct;
33(3):231-41.
PMID: 10533839
The purpose of this study was to analyse slow brain potentials (SPs) during visual monitoring, needed to perform the clock-monitoring task (CMT). This task was successfully applied in behavioural studies,...

Int J Psychophysiol
. 1999 Jun;
32(2):107-18.
PMID: 10380945
EEG changes related to the amount of information held in memory during a 4-s retention period were studied. The predictability of the amount of information held in memory was varied....

Neuroreport
. 1998 Nov;
9(14):3229-32.
PMID: 9831456
Mobile phones emit a pulsed high-frequency electromagnetic field (PEMF) which may penetrate the scalp and the skull. Increasingly, there is an interest in the interaction of this pulsed microwave radiation...

Bioelectromagnetics
. 1998 Sep;
19(6):384-7.
PMID: 9738529
The influence of electromagnetic fields (EMF) emitted by cellular phones on preparatory slow brain potentials (SP) was studied in two different experimental tasks: In the first, healthy male human subjects...

Biol Psychol
. 1998 Apr;
47(2):137-58.
PMID: 9554185
A series of experiments were conducted to systematically evaluate the relative contributions of task difficulty and stimulus probability to P300 amplitudes. Scalp event-related potentials (ERPs) were recorded and the topographic...

Neuroreport
. 1995 Dec;
7(1):241-5.
PMID: 8742461
It has been reported that frontal lobe structures are critical for the generation of P300 activity in the human event-related potential (ERP) evoked by novel events. In this study spatial-temporal...
