Increasing depth of binocular rivalry suppression along two visual pathways.

Binocular rivalry refers to the alternating perception that occurs when the two eyes are presented with incompatible stimuli: one monocular image is seen exclusively for several seconds before disappearing as the other image comes into view. The unseen ...

CSF galanin and cognition after shunt surgery in normal pressure hydrocephalus.

BACKGROUND: "Normal" pressure hydrocephalus (NPH) is associated with injury to neurotransmitter and neuropeptide systems that recovers after surgery. This could be linked to changes in galanin, a neuropeptide with inhibitory effects on basal forebrain ...

Orientation-specific adaptation in human visual cortex.

Nearly all methods for analyzing and interpreting functional magnetic resonance imaging (fMRI) data assume that the fMRI signal behaves in an approximately linear manner. However, it has been shown that the mean fMRI response to a pair of briefly ...

Human striatal response to salient nonrewarding stimuli.

Although one proposed function of both the striatum and its major dopamine inputs is related to coding rewards and reward-related stimuli, an alternative view suggests a more general role of the striatum in processing salient events, regardless of their ...

Visual feature integration theory: past, present, and future.

Visual feature integration theory was one of the most influential theories of visual information processing in the last quarter of the 20th century. This article provides an exposition of the theory and a review of the associated data. In the past much ...

Electroencephalographic signatures of attentional and cognitive default modes in spontaneous brain activity fluctuations at rest.

We assessed the relation between hemodynamic and electrical indices of brain function by performing simultaneous functional MRI (fMRI) and electroencephalography (EEG) in awake subjects at rest with eyes closed. Spontaneous power fluctuations of ...

An integrated network for invariant visual detection and recognition.

We describe an architecture for invariant visual detection and recognition. Learning is performed in a single central module. The architecture makes use of a replica module consisting of copies of retinotopic layers of local features, with a particular ...

Restoring attention in pregnancy: the natural environment.

The purpose of this quasi-experimental pretest-posttest study was to test whether regularly spending time in the natural environment would improve concentration for women in the third trimester of pregnancy, a time when women rely on their ability to ...

Changes of effective connectivity between the lateral and medial parts of the prefrontal cortex during a visual task.

Structural equation modelling was used to study the change of connectivity during a visual task with continuous variation of the attention load. The model was based on areas defined by the haemodynamic responses described elsewhere [Mazoyer, P., Wicker, ...

Age and responding-hand related changes in performance of neurologically normal subjects on the line-bisection and chimeric-faces tasks.

This study investigated age and responding-hand (left, right, and bimanual) related changes in visuospatial attention. Two tasks were completed by 107 neurologically normal right-handed subjects ranging in age from 5 to 70 years and distributed across ...
