Compulsory averaging of crowded orientation signals in human vision

L Parkes, J Lund, A Angelucci, JA Solomon… - Nature …, 2001 - nature.com
A shape can be more difficult to identify when other shapes are near it. For example, when
several grating patches are viewed parafoveally, observers are unable to report the …

Normal cerebral perfusion measurements using arterial spin labeling: reproducibility, stability, and age and gender effects

LM Parkes, W Rashid, DT Chard… - Magnetic Resonance in …, 2004 - Wiley Online Library
Before meaningful conclusions can be drawn from clinical measures of cerebral blood
perfusion, the precision of the measurement must be determined and set in the context of inter‐ …

Localizing human visual gamma-band activity in frequency, time and space

…, JM Schoffelen, R Oostenveld, LM Parkes… - Neuroimage, 2006 - Elsevier
Neuronal gamma-band (30–100 Hz) synchronization subserves fundamental functions in
neuronal processing. However, different experimental approaches differ widely in their …

Improved accuracy of human cerebral blood perfusion measurements using arterial spin labeling: accounting for capillary water permeability

LM Parkes, PS Tofts - … in Medicine: An Official Journal of the …, 2002 - Wiley Online Library
A two‐compartment exchange model for perfusion quantification using arterial spin labeling
(ASL) is presented, which corrects for the assumption that the capillary wall has infinite …

patients with nonrefractory depressive disorder (NDD), and healthy control subjects by …

Quantifying the spatial resolution of the gradient echo and spin echo BOLD response at 3 Tesla

LM Parkes, JV Schwarzbach, AA Bouts… - Magnetic resonance …, 2005 - Wiley Online Library
The blood oxygen level dependent (BOLD) response, as measured with fMRI, offers good
spatial resolution compared to other non‐invasive neuroimaging methods. The use of a spin …

Combining EEG and fMRI to investigate the post-movement beta rebound

LM Parkes, MCM Bastiaansen, DG Norris - Neuroimage, 2006 - Elsevier
The relationship between synchronous neuronal activity as measured with EEG and the
