An MEG study of picture naming. (magnetoencephalography)
September 1, 1998... INTRODUCTION Salmelin, Hari, Lounasmaa, and Sams (1994) reported the first successful magnetoencephalograph (MEG) study of picture naming. The study demonstrated that picture naming is a feasible task in MEG studies of language production and...

What processing is impaired in apperceptive agnosia? Evidence from normal subjects.
September 1, 1998... INTRODUCTION Among the problems that the visual system must solve, object representation and identification are perhaps the most difficult. Attempts to understand object representation processes have come from several disciplines, including...

Neuropsychological evidence of an integrated visuotactile representation of peripersonal space in humans.
September 1, 1998... INTRODUCTION Patients with unilateral brain lesion may fail to report a single stimulus presented on the contralesional side when a competing stimulus is shown simultaneously on the ispilesional side, even though they can report either...

Neural mechanisms of involuntary attention to acoustic novelty and change.
September 1, 1998... INTRODUCTION It is a common experience that, even during intensive task performance, our attention can be involuntarily engaged by acoustic changes occurring unexpectedly in the environment. The present study used a combination of behavioral...

Reactivation of a dormant representation of an auditory stimulus feature.
September 1, 1998... INTRODUCTION Research with the mismatch negativity (MMN) component of event-related potentials (ERPs) has revealed a system that detects changes in the acoustic environment in an automatic manner (Naatanen, 1992). This deviance detection...

Why faces may be special: evidence of the inversion effect in chimpanzees.
September 1, 1998... INTRODUCTION Faces are one of, if not the most important and salient class of stimuli involved in social communication. They provide invariant information about age, sex, individual identity, and emotion (Brothers, 1990; Buck, 1988; Tomonaga,...

A computational role for dopamine delivery in human decision-making.
September 1, 1998... INTRODUCTION Even for the simplest creatures, there are vast complexities inherent in any decision-making task. Nonetheless, any creature has limited available time in which to arbitrate decisions. Decision-making is likely to possess...

Reading the windows to the soul: evidence of domain-specific sparing in Williams syndrome.
September 1, 1998... INTRODUCTION Individuals with Williams syndrome have a unique cognitive-behavioral phenotype that includes relative sparing in the domains of language and face processing in the presence of marked deficits in visual-spatial cognition and mild...

Frontal lobe contributions to theory of mind.
September 1, 1998... INTRODUCTION Humans, like many other species, use a variety of cues (facial expression, body posture, tone of voice) to predict others' behavior. An animal that recognizes another animal's threatening body posture, for example, might produce a...

Interview with Apostolos P. Georgopoulos. (neurophysiologist)(Interview)
September 1, 1998... APG studied Medicine and Physiology at the University of Athens in Greece where he obtained his M.D. and Ph.D. degrees. He was trained in neurophysiology by Vernon B. Mountcastle at Johns Hopkins and, after a brief return to Athens, he came back...
