A distinct neurocognitive phenotype in female fragile-X premutation carriers assessed with visual attention tasks.

Premature ovarian failure (POF) and underlying hormonal changes are recognized as a distinct phenotype in female fragile-X premutation carriers. Neurocognitive deficits, in particular mental retardation, are associated with the full mutation in males and ...

Recognition thresholds for plane-rotated pictures of familiar objects.

We investigated picture plane rotation effects on the minimum stimulus duration required to recognise pictures of familiar objects in a picture-word verification task. Participants made unspeeded responses, selecting from 126 written alternatives. Longer ...

Exocentric pointing to opposite targets.

We use an exocentric pointing task to study exocentric visual directions to targets that are opposite to a pointer relative to the observer. (The apparent distance between the target and the pointer always exceeded 90 degrees of visual angle.) All ...

Columns for complex visual object features in the inferotemporal cortex: clustering of cells with similar but slightly different stimulus selectivities.

Cells in the inferotemporal cortex (area TE) selectively respond to complex visual object features and those that respond to similar features cluster in a columnar region elongated vertical to the cortical surface. What are the functional roles of the ...

Towards a theory of the laminar architecture of cerebral cortex: computational clues from the visual system.

One of the most exciting and open research frontiers in neuroscience is that of seeking to understand the functional roles of the layers of cerebral cortex. New experimental techniques for probing the laminar circuitry of cortex have recently been ...

Categorization of infant-directed speech: development from 4 to 6 months.

To extend a previous finding that 6-month-old infants categorized low-pass filtered infant-directed (ID) utterances, we examined a) 6-month-old infants categorization of more naturalistic, unfiltered ID utterances and b) the developmental progression of ...

Efficient acquisition of human retinotopic maps.

A bifield stimulation method for rapidly obtaining retinotopic maps in human occipital cortex using functional MRI was compared to conventional unifield stimulation. While maintaining central fixation, each participant viewed the conventional display, ...

Naïve and experienced judgments of stimulus-response compatibility: implications for interface design.

Many design guidelines encourage maintaining stimulus-response compatibility whenever possible. Payne found that naïve judgments for different stimulus-response (S-R) mappings were not very accurate, and suggested that designers may not be able to ...

After-effects of visuo-manual adaptation to prisms on body posture in normal subjects.

Postural equilibrium is known to be controlled by sensorimotor reflexes and automatic control loops but also depends on high-level body representation in space, probably implicating the right temporoparietal cortex. Indeed, short-term prism adaptation to ...

Olfaction and depth of word processing: a magnetoencephalographic study.

Using a whole-cortex magnetoencephalograph, magnetic field changes were recorded to describe brain activities related to simultaneous visual and olfactory processing and to detect odor-related influences on verbal information processing. Words had to be ...
