Auditory Priming within and across Modalities: Evidence from Positron Emission Tomography.(Statistical Data Included)
July 1, 1999... INTRODUCTION Priming refers to a change in the ability to identify or produce an object or word as a result of a specific prior encounter with the item (Tulving & Schacter, 1990). Priming does not require conscious or explicit recollection...

Can Face Recognition Really be Dissociated from Object Recognition?(Statistical Data Included)
July 1, 1999... "I shouldn't know you again if we did meet," Humpty Dumpty replied in a discontented tone. . . . "You're so exactly like other people." 'The face is what one goes by, generally," Alice remarked in a thoughtful tone. 'That's just what I...

Delineating Necessary and Sufficient Neural Systems with Functional Imaging Studies of Neuropsychological Patients.
July 1, 1999... INTRODUCTION Functional neuroimaging in normal subjects reveals distributed brain systems that can be considered sufficient to perform a task but does not distinguish the relative contributions of the subcomponents involved. Some...

The Neural Circuitry Involved in the Reading of German Words and Pseudowords: A PET Study.
July 1, 1999... INTRODUCTION Most models of normal reading assume that reading words of a familiar language is a complex process composed of a number of subcomponents, including access to orthographic and phonological word forms and activation of the...

The Neural Substrate of Picture Naming.
July 1, 1999... INTRODUCTION Pictures make up one of the comprehensive classes of symbols for objects that constitute the inventory of our everyday world. Cognitive theories of object identification and language suggest that for picture naming to occur, a...

Interactive Processing of Sensory Input and Motor Output in the Human Hippocampus.
July 1, 1999... INTRODUCTION A widely held view of brain organization is that the motor system is activated only after the immediate sensory scene is fully elaborated in sensory networks. However, recent studies of visuomotor integration suggest that the...

Short- and Long-Delay Intracranial ERP Repetition Effects Dissociate Memory Systems in the Human Brain.
July 1, 1999... INTRODUCTION On a variety of tasks, performance is improved when a stimulus has been previously encountered in the list (Clarke & Morton, 1983; Forbach, Stanners, & Hochhaus, 1974; Scarborough, Cortese, & Scarborough, 1977; Winnick &...

Illusory Contour Perception and Amodal Boundary Completion: Evidence of a Dissociation Following Callosotomy.
July 1, 1999... INTRODUCTION To perceive objects in the environment as unified wholes, the visual system must often extrapolate from incomplete contour or boundary information. Under certain conditions extrapolated contours are perceived in areas of...

New Approaches to Functional Neuroenergetics.
July 1, 1999... INTRODUCTION The coupling between brain energy metabolism and neuronal activity has, for more than a century, allowed researchers to monitor brain function (Roy & Sherrington, 1890; Siesjo, 1973; Sokoloff, 1981). A breakthrough in this...
