Maternal supplementation with very-long-chain n-3 fatty acids during pregnancy and lactation augments childrens IQ at 4 years of age.

OBJECTIVES: Docosahexaenoic acid (DHA; 22:6 n-3) and arachidonic acid (AA; 20:4 n-6) are important for development of the central nervous system in mammals. There is a growth spurt in the human brain during the last trimester of pregnancy and the first ...

New objects, not new features, trigger the attentional blink.

When two different targets must be selected from a rapid serial visual presentation (RSVP) of images, perception of the second target will be markedly reduced if it is presented within about a half second of the first. Known as the attentional blink ...

Social cognition in frontotemporal dementia and Huntingtons disease.

Frontotemporal dementia (FTD) and Huntingtons disease (HD) are degenerative disorders, with predominant involvement, respectively of frontal neocortex and striatum. Both conditions give rise to altered social conduct and breakdown in interpersonal ...

Dissociable effects of dopaminergic therapy on spatial versus non-spatial working memory in Parkinsons disease.

There is now evidence for definite and early cognitive deficits in Parkinsons disease (PD), involving, in particular, executive functions and working memory. However, the distinction between visuo-spatial and non-spatial working memory deficits and the ...

From acting on to acting with: the functional anatomy of object-oriented action schemata.

In this chapter it is proposed that object-based actions can be broadly classified into types. In the first, objects are acted on without a specific purpose. In the second, objects are acted with. In the latter case the grasp reflects the subsequent goal ...

Mapping of the neuronal networks of human cortical brain functions.

OBJECTIVE: The principles and methodology of event-related fMRI, electromagnetic source imaging and intracranial evoked potentials will be described along with some examples of the mapping of the neuronal networks of human cortical brain functions with ...

Different brain mechanisms mediate two strategies in arithmetic: evidence from Event-Related brain Potentials.

Participants were asked to verify if complex additions were smaller than 100 or not. Two hundred and forty arithmetic problems were presented, with half the problems being small-split problems (i.e. proposed sums were 2 or 5% away from 100) and half ...

Relative influences of affect and cognition on behavior: are feelings or beliefs more related to blood donation intentions?

This study tested the relative predictive power of affect and cognition on global attitude and behavioral intention within the tripartite model of attitude structure. Participants (N = 264) completed questionnaires that included an item regarding blood ...

Is it an animal? Is it a human face? Fast processing in upright and inverted natural scenes.

Object categorization can be extremely fast. But among all objects, human faces might hold a special status that could depend on a specialized module. Visual processing could thus be faster for faces than for any other kind of object. Moreover, because ...

Feature binding in object-file representations of multiple moving items.

Maintenance of episodic representations by feature-location binding is important for visual cognition. It has been proposed that we can hold and update coherent episodic representations of up to four objects. This study investigated the dynamic ...
