Temporal performance parameters vary across the visual field. Their topographical distributions relative to each other and relative to basic visual performance measures and their relative change over the life span are unknown. Our goal was to characterize the topography and age-related change of temporal performance. We acquired visual field maps in 95 healthy participants (age: 10-90 years): p...

The apparently effortless identification of speech is one of the human auditory cortex' finest and least understood functions. This is partly due to difficulties to tease apart effects of acoustic and phonetic attributes of speech sounds. Here we present evidence from magnetic source imaging that the auditory cortex represents speech sounds (such as [g] and [t]) in a topographically orderly fas...

Scholars writing books that are widely used to support teaching in higher education may be undervalued due to a lack of evidence of teaching value. Whilst sales data may give credible evidence for textbooks, it may poorly reflect educational uses of other types of books. As an alternative, this article proposes a method to automatically search for mentions of books in online academic course syl...

In adherent cells, the relevance of a physical mechanotransduction pathway provided by the perinuclear actin cap stress fibers has recently emerged. Here, we investigate the impact of a functional actin cap on the cellular adaptive response to topographical cues and uniaxial cyclic strain. Lmna-deficient fibroblasts are used as a model system because they do not develop an intact actin cap, but...

OBJECTIVE To test the hypothesis that visual memory for faces can be dissociated from visual memory for topographical material. METHOD A patient who developed a global amnesic syndrome after acute carbon monoxide poisoning is described. A neuroradiological examination documented severe bilateral atrophy of the hippocampi. RESULTS Despite a severe anterograde memory disorder involving verbal...

The ventrolateral nuclear group of the dorsal thalamus in the monkey consists of the large cell mass lying between the external and internal medullary laminae rostral to the pulvinar. Fibers from these nuclei terminate on a sector occupying the middle portion of the dorsolateral cerebral cortex. Previous investigators using, in most instances, the method of retrograde degeneration, have determi...

Due to their interactivity and to the sense of presence they afford, virtual environments constitute an interesting opportunity to study spatial cognition. In accordance with this perspective, we aimed to introduce a spatial test in virtual simulation in order to investigate the survey spatial ability in patients with topographical disorientation. To do this, we used the "planning in advance ta...

Touching is a powerful means for eliciting sexual arousal. Here, we establish the topographical organization of bodily regions triggering sexual arousal in humans. A total of 704 participants were shown images of same and opposite sex bodies and asked to color the bodily regions whose touching they or members of the opposite sex would experience as sexually arousing while masturbating or having...

Operations with flexible, compliant manipulators over large workspaces relative to the manipulator are complicated by sensor noise, vibration, and measurement bias. These difficulties are compounded by unstructured environments, such as those encountered in humanitarian demining. By taking advantage of the static structure of the terrain and the manipulator’s fundamental mechanical characterist...
