Domain-specific knowledge systems in the brain: the animate-inanimate distinction.
January 1, 1998... INTRODUCTION How is conceptual knowledge organized in the brain? Evidence relevant to this issue is provided by the patterns of semantic processing deficits in brain-damaged subjects, especially those deficits that seem to selectively affect...

A model of reaching dynamics in primary motor cortex.
January 1, 1998... INTRODUCTION The primary motor cortex, M1, plays a role in the representation of most voluntary movements. This is seen in movement-specific neural activity that occurs before and during movements, during learned delays preceding movements,...

Binocular rivalry and motion perception.
January 1, 1998... INTRODUCTION Visual perception is the culmination of information processing within hierarchically organized stages, with different qualitative aspects of the visual scene engaging populations of neurons distributed among numerous, distinct...

Knowing where things are: parahippocampal involvement in encoding object locations in virtual large-scale space.
January 1, 1998... INTRODUCTION Study of the nonhuman medial temporal lobe suggest it has a significant role in processing spatial information that is independent of the location or orientation of a navigating animal (i.e., processing spatial information in an...

Category-specific semantic deficits in focal and widespread brain damage: a computational account.
January 1, 1998... INTRODUCTION Semantic memory impairments can be caused by several types of neuropathology, including Alzheimer's disease (e.g., Nebes, 1989), herpes simplex encephalitis (e.g., Warrington & Shallice, 1984), and cerebrovascular accidents (e.g.,...

Visuospatial attention shift and motor responses in cerebellar disorders.
January 1, 1998... Introduction Recent studies have elucidated some of the contributions of the cerebellum to non-motor higher cognitive functions (Ivry & Baldo, 1992; Schmahmann, 1991). Cumulative evidence suggests that the cerebellum and associated brain stem...

A computational model of how the basal ganglia produce sequences.
January 1, 1998... INTRODUCTION The basal ganglia are a collection of subcortical structures that are relatively large in primates, particularly in humans. Although much is now known about both the types of neurons that comprise these structures and their...

The effect of pictorial illusion on prehension and perception.
January 1, 1998... INTRODUCTION Vision provides us with a vast array of information about the world around us - information that can direct our thoughts and guide our actions. Yet our perception of the world can sometimes bc misleading. Objects can appear to be...

Switching attention without shifting the spotlight: object-based attentional modulation of brain potentials.
January 1, 1998... INTRODUCTION The visual system can be flooded by the information coming from a rich scene. All the input cannot be processed with the same priority. Attentional selection of visual information for further processing could occur on the basis of...
