Striate cortex (V1) activity gates awareness of motion

Nature Neuroscience, 2005
A key question in understanding visual awareness is whether any single cortical area is indispensable. In a transcranial magnetic stimulation experiment, we show that observers' awareness of activity in extrastriate area V5 depends on the amount of activity in striate cortex (V1).

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Identifying temporal and causal contributions of neural processes underlying the Implicit Association Test (IAT)

Frontiers in Human Neuroscience, 2012
The Implicit Association Test (IAT) is a popular behavioral measure that assesses the associative strength between outgroup members and stereotypical and counterstereotypical traits.

Fast Synchronization of Perpetual Grouping in Laminar Visual Cortical Circuits [PDF]

, 2004
Perceptual grouping is well-known to be a fundamental process during visual perception, notably grouping across scenic regions that do not receive contrastive visual inputs. Illusory contours are a classical example of such groupings.

The Development of Trait Anxiety in Nonhuman Primates During the First Year of Life

Developmental Science, Volume 29, Issue 2, March 2026.
ABSTRACT Anxious temperament (AT) is a nonhuman primate phenotype that models childhood behavioral inhibition, a prominent risk factor for anxiety disorders and stress‐related psychopathology. To understand its earliest antecedents, we characterized AT's developmental trajectory over the first year of life.

Population Receptive Field Properties from fMRI and Electrocorticography in Striate and Extrastriate Cortex of the Same Subject

i-Perception, 2012
Population receptive field (pRF) modelling reconstructs the properties of visually responsive neuronal populations, typically using fMRI in humans. However, fMRI is an indirect measure of neural activity.

Two-photon imaging of calcium in virally transfected striate cortical neurons of behaving monkey.

PLoS ONE, 2010
Two-photon scanning microscopy has advanced our understanding of neural signaling in non-mammalian species and mammals. Various developments are needed to perform two-photon scanning microscopy over prolonged periods in non-human primates performing a ...

Temporal Dynamics of Binocular Disparity Processing with Corticogeniculate Interactions [PDF]

, 1999
A neural model is developed to probe how corticogeniculate feedback may contribute to the dynamics of binocular vision. Feedforward and feedback interactions among retinal, lateral geniculate, and cortical simple and complex cells are used to simulate ...

Striate cortex, extrastriate cortex, and colliculus: some new approaches

, 1996
AbstractMany aspects of visual development over the first months of life can be understood in terms of visual function becoming increasingly dominated by cortical processes. More recent formulations have developed this idea in terms of cortical processes modulating continuing visual functions of subcortical structures and of differential development of
