Reduced resting-state brain activity in the "default network" in normal aging (2008)
Damoiseaux, J.S., Beckmann, C.F., Arigita, E.J. Sanz, Barkhof, F., Scheltens, Ph., Stam, C.J., ...
Normal aging is associated with cognitive decline. Functions such as attention, information processing, and working memory are compromised. It has been hypothesized that not only regional changes,...
Skantzos Beckmann, C. F. Beckmann
We present exact analytical equilibrium solutions for a class of recurrent neural network models, with both sequential and parallel neuronal dynamics, in which there is a tunable competition between...
Variability in fMRI: A Re-Examination of Intersession Differences (2005)

Color of scents: Chromatic stimuli modulate odor responses in the human brain (2005)
Osterbauer, R. A., Matthews, P. M., Jenkinson, M., Beckmann, C. F., Hansen, P. C., Calvert, G. A.
Color has a profound effect on the perception of odors. For example, strawberry-flavored drinks smell more pleasant when colored red than green and descriptions of the "nose" of a wine are...
ICA-Based Segmentation of the Brain on Perfusion Data (2003)
Tasciyan, T. A., Beckmann, C. F., Morris, E. D., Smith, S. M.
An Independent Component Analysis (ICA) based segmentation technique is presented allowing the quantitative assessment of cerebral blood volume (CBV), cerebral blood flow (CBF) and mean transit time...
Magnetic Resonance Imaging Perfusion, Dynamic Susceptibility (2001)
Keyw Or Ds, T. A. Tasciyan, C. F. Beckmann, E. D. Morris, S. M. Smith
INTRODUCTION The segmentation of perfusion images is essential for tissue-specific quantitative assessment of cerebral blood volume (CBV), cerebral blood flow (CBF), and mean transit time (MTT)...
Consistent resting-state networks across healthy subjects
Damoiseaux, J. S., Barkhof, F., Scheltens, P., Stam, C. J., Smith, S. M., ...
Functional MRI (fMRI) can be applied to study the functional connectivity of the human brain. It has been suggested that fluctuations in the blood oxygenation level-dependent (BOLD) signal during...
