In 64% of Rembrandt's female portraits the poser's left-cheek faces the viewer. However, this occurs in only 33% of his male portraits. This asymmetry is consistent with viewers rating Rembrandt's left-cheeked male portraits as likely to be avoided, which may reflect that aggressive displays of dominance are governed by the contralateral right-hemisphere, while rating left-cheeked female faces ...

human species and is relevant in clinical practice—to excimer laser photorefractive keratectomy (PRK) in particular. Due to the complexity of the underlying physiological mechanisms, there is no single definition that applies to all aspects of ocular dominance. Nevertheless, a clinically useful definition would be, “The dominant eye is the eye that is preferred in monocular viewing or in pointi...

Objective: to describe our experience with pre-operative evaluation of intracranial vascular malformations using functional magnetic resonance (fmRi). Method: Assessment of eight patients with cerebral vascular malformations (seven arteriovenous malformations [Avm] and one cavernous malformation) referred for pre-operative fmRi mapping of the eloquent cortex. An oxygen level-dependent technique...

Recent studies of exceptional language development and functioning in mentally retarded people raise questions regarding basic issues in language disorders. These studies are summarised and their implications discussed. Possible reasons for the existence of such cases are examined including language training, general cognitive functioning, working memory, cerebral dominance, and deep-seated var...

A conductor suddenly developed global aphasia and severe ideomotor apraxia as a result of an infarct in the territory of the left middle cerebral artery. Although aphasia and apraxia remained unchanged during the following six years, his musical capacities were largely spared and he was still able to conduct. This case provides some evidence in favour of right hemisphere dominance for music.

The present review surveys a broad range of findings on the functions of the rodent prefrontal cortex (PFC) in the context of the known pathophysiology of attention-deficit/hyperactivity disorder (ADHD). An overview of clinical findings concludes that dysfunction of the right PFC plays a critical role in ADHD and that a number of early developmental factors conspire to increase the risk of the ...

The cerebral hemispheres of the human brain have unique functional properties of information processing; an asymmetry that captures cerebral lateralization. Among cognitive functions, language is one of the most lateralized with left-sided dominance for the production and processing of language. Previous work has shown that the foundation of language circuitry emerges in the late second and thi...

For over a century, evidence has been gathered to indicate that the two cerebral hemispheres of the human brain each tend to have their own behavioral specializations. An issue that has long been of interest to parapsychologists is whether the ostensibly anomalous behavioral phenomenon of “extrasensory perception” (ESP), in which a person seems to obtain veridical information about other people...
