The spiking response of a primary visual cortical cell to a stimulus placed within its receptive
field can be up- and down-regulated by the simultaneous presentation of objects or scenes …

Individual motion measurements are inherently ambiguous since the component of motion
parallel to a homogeneous translating edge cannot be measured. Numerous models have …

We studied direction discrimination for lines moving obliquely relative to their orientation.
Manipulating contrast, length and duration of motion, we found systematic errors in direction …

Pupil size not only varies to changes in illumination but is also modulated by several
cognitive factors, making it a potentially versatile physiological marker of cortical states. We …

Introduction Blood-based biomarkers of pathophysiological brain amyloid β (Aβ)
accumulation, particularly for preclinical target and large-scale interventions, are warranted to …

The Precision Neurology development process implements systems theory with system
biology and neurophysiology in a parallel, bidirectional research path: a combined hypothesis-…

Visual analyses of form and motion proceed along parallel streams. Unified perception of
moving forms requires interactions between these streams, although whether the interactions …

Introduction Observational multimodal neuroimaging studies indicate sex differences in
Alzheimer's disease pathophysiological markers. Methods Positron emission tomography brain …

The integration of information from different sensory modalities has many advantages for
human observers, including increase of salience, resolution of perceptual ambiguities, and …

Introduction The longitudinal trajectories of functional brain dynamics and the impact of genetic
risk factors in individuals at risk for Alzheimer's disease are poorly understood. Methods …
