Self-Organizing Dynamics of Lexical Access in Normals and Aphasics.
February 15, 2001... Abstract The goal of this article is to illustrate the application of selforganizing dynamics in the design of a model of lexical access. We focus particularly on the mapping of sound structure on to the lexicon and the influence of that...

A Limit to the Speed of Processing in Ultra-Rapid Visual Categorization of Novel Natural Scenes.(Statistical Data Included)
February 15, 2001... Abstract * The processing required to decide whether a briefly flashed natural scene contains an animal can be achieved in 150 msec (Thorpe, Fize, & Marlot, 1996). Here we report that extensive training with a subset of photographs over...

Binding Personal and Peripersonal Space: Evidence from Tactile Extinction.(Statistical Data Included)
February 15, 2001... Sandeep Vaishnavi [1,2] Jesse Calhoun [1] Anjan Chatterjee [1,2] Abstract * Behavioral and neurophysiological studies suggest that the brain constructs different representations of space. Among these representations are...

Encoding of Categories by Noncategory-Specific Neurons in the Inferior Temporal Cortex.(Statistical Data Included)
February 15, 2001... Elizabeth Thomas [1] Marc M. Van Hulle [2] Rufin Vogels [2] Abstract * In order to understand how the brain codes natural categories, e.g., trees and fish, recordings were made in the anterior part of the macaque inferior...

Brain Potentials Reflect Behavioral Differences in True and False Recognition.(Statistical Data Included)
February 15, 2001... Tim Curran [1] Daniel L. Schacter [2] Marcia K. Johnson [3] Ruth Spinks [1] Abstract * People often falsely recognize nonstudied lures that are semantically similar to previously studied words. Behavioral research...

Motor Learning of Compatible and Incompatible Visuomotor Maps.(Statistical Data Included)
February 15, 2001... Scott T. Grafton [1] Joanna Salidis [2] Daniel B. Willingham [2] Abstract * Brain imaging studies demonstrate increasing activity in limb motor areas during early motor skill learning, consistent with functional...

Abnormal Processing of Social Information from Faces in Autism.(Statistical Data Included)
February 15, 2001... Abstract * Autism has been thought to be characterized, in part, by dysfunction in emotional and social cognition, but the pathology of the underlying processes and their neural substrates remain poorly understood. Several studies have...

Different Brain Mechanisms Mediate Sensitivity to Sensory Consonance and Harmonic Context: Evidence from Auditory Event-Related Brain Potentials.(Statistical Data Included)
February 15, 2001... Pascaline Regnault [1] Emmanuel Bigand [2] Mireille Besson [1] Abstract The goal of this study was to analyze the time-course of sensory (bottom-up) and cognitive (top-down) processes that govern musical harmonic...

A Model of Saccade Initiation Based on the Competitive Integration of Exogenous and Endogenous Signals in the Superior Colliculus.
February 15, 2001... Thomas P. Trappenberg [1] Michael C. Dorris [2] Douglas P. Munoz [2] Raymond M. Klein [3] Abstract * Significant advances in cognitive neuroscience can be achieved by combining techniques used to measure behavior and...

Relative Shift in Activity from Medial to Lateral Frontal Cortex During Internally Versus Externally Guided Word Generation.(Statistical Data Included)
February 15, 2001... Abstract * Goldberg (1985) hypothesized that as language output changes from internally to externally guided production, activity shifts from supplementary motor area (SMA) to lateral premotor areas, including Broca's area. To test this...
