Liu M, Fenwick P, Lumsden J, Lever C, Stephan K, Ioannides A
Hum Brain Mapp
. 2010 Apr;
4(4):254-64.
PMID: 20408203
We compare estimates of three-dimensional brain activity extracted from averaged and from selected single-trial magnetoencephalographic signals, in order to study activation sequences related to motor preparation, inhibition, and movement, cued...

Lithari C, Frantzidis C, Papadelis C, Vivas A, Klados M, Kourtidou-Papadeli C, et al.
Brain Topogr
. 2010 Jan;
23(1):27-40.
PMID: 20043199
Men and women seem to process emotions and react to them differently. Yet, few neurophysiological studies have systematically investigated gender differences in emotional processing. Here, we studied gender differences using...

Okazaki Y, Abrahamyan A, Stevens C, Ioannides A
Neuroscience
. 2008 Mar;
152(4):1130-44.
PMID: 18355971
Despite the complete imprint of a visual scene on the retina, the brain selects particular items for further processing. However, there is considerable debate about when and where the first...

Koutras A, Kostopoulos G, Ioannides A
IEEE Trans Biomed Eng
. 2008 Mar;
55(3):957-69.
PMID: 18334387
This paper describes the theoretical background of a new data-driven approach to encephalographic single-trial (ST) data analysis. Temporal constrained source extraction using sparse decomposition identifies signal topographies that closely match...

Iida T, Fenwick P, Ioannides A
J Oral Rehabil
. 2007 Jun;
34(7):487-96.
PMID: 17559616
The reasons for unconscious teeth clenching have not been clarified. The long-term goal of our project was the elucidation of processing in the brain immediately before unconscious teeth clenching, in...

Hironaga N, Ioannides A
Neuroimage
. 2006 Dec;
34(4):1519-34.
PMID: 17187995
A family of methods, collectively known as independent component analysis (ICA), has recently been added to the array of methods designed to decompose a multi-channel signal into components. ICA methods...

Liu L, Plomp G, van Leeuwen C, Ioannides A
Neuroscience
. 2006 Jun;
141(3):1585-97.
PMID: 16753265
The visual system rapidly completes a partially occluded figure. We probed the completion process by using priming in combination with neuroimaging techniques. Priming leads to more efficient visual processing and...

Laskaris N, Liu L, Ioannides A
Neuroimage
. 2003 Oct;
20(2):765-83.
PMID: 14568450
Cortical activity evoked by repeated identical sensory stimulation is extremely variable. The source of this variability is often assigned to "random ongoing background activity" which is considered to be irrelevant...

Liu L, Fenwick P, Laskaris N, Schellens M, Poghosyan V, Shibata T, et al.
Neuroscience
. 2003 Aug;
121(1):141-54.
PMID: 12946707
Somatosensory stimulation of primary somatosensory cortex (SI) using frequency discrimination offers a direct, well-defined and accessible way of studying cortical decisions at the locus of early input processing. Animal studies...

Consistent and precise localization of brain activity in human primary visual cortex by MEG and fMRI
Moradi F, Liu L, Cheng K, Waggoner R, Tanaka K, Ioannides A
Neuroimage
. 2003 Apr;
18(3):595-609.
PMID: 12667837
The tomographic localization of activity within human primary visual cortex (striate cortex or V1) was examined using whole-head magnetoencephalography (MEG) and 4-T functional magnetic resonance imaging (fMRI) in four subjects....
