Differentiating sensitivity of post-stimulus undershoot under diffusion weighting: implication of vascular and neuronal hierarchy.
(PLoS One, 2008-08-13)
The widely used blood oxygenation level dependent (BOLD) signal during brain activation, as measured in typical fMRI methods, is composed of several distinct phases, the last of which, and perhaps the least understood, is ...
Analysis of Smoking Cessation Patterns Using a Stochastic Mixed-Effects Model With a Latent Cured State
(Journal of the American Statistical Association, 2008-09)
Corollary discharge circuits in the primate brain.
(Curr Opin Neurobiol, 2008-12)
Movements are necessary to engage the world, but every movement results in sensorimotor ambiguity. Self-movements cause changes to sensory inflow as well as changes in the positions of objects relative to motor effectors ...
Electronic health records, medical research, and the Tower of Babel.
(N Engl J Med, 2008-04-17)
Neuronal adaptation caused by sequential visual stimulation in the frontal eye field.
(J Neurophysiol, 2008-10)
Images on the retina can change drastically in only a few milliseconds. A robust description of visual temporal processing is therefore necessary to understand visual analysis in the real world. To this end, we studied subsecond ...
Oxygen for relief of dyspnoea in mildly- or non-hypoxaemic patients with cancer: a systematic review and meta-analysis.
(Br J Cancer, 2008-01-29)
The aim of this study was to determine the efficacy of palliative oxygen for relief of dyspnoea in cancer patients. MEDLINE and EMBASE were searched for randomised controlled trials, comparing oxygen and medical air in cancer ...
Neuronal adaptation: Delay compensation at the level of single neurons?
(Behavioral and Brain Sciences, 2008-04-01)
Saccades divide visual input into rapid, discontinuous periods of stimulation on the retina. The response of single neurons to such sequential stimuli is neuronal adaptation; a robust first response followed by ...
Comorbidity, age, race and stage at diagnosis in colorectal cancer: a retrospective, parallel analysis of two health systems.
(BMC Cancer, 2008-11-25)
BACKGROUND: Stage at diagnosis plays a significant role in colorectal cancer (CRC) survival. Understanding which factors contribute to a more advanced stage at diagnosis is vital to improving overall survival. Comorbidity, ...
Molecular mapping of movement-associated areas in the avian brain: a motor theory for vocal learning origin.
(PLoS One, 2008-03-12)
Vocal learning is a critical behavioral substrate for spoken human language. It is a rare trait found in three distantly related groups of birds-songbirds, hummingbirds, and parrots. These avian groups have remarkably similar ...
Visual perception and corollary discharge.
Perception depends not only on sensory input but also on the state of the brain receiving that input. A classic example is perception of a stable visual world in spite of the saccadic eye movements that shift the images ...
