Scene-specific memory for objects: a model of episodic memory impairment in monkeys with fornix transection. (Cover Story)
September 22, 1994... INTRODUCTION The search for an experimental analogue of human amnesia in the Rhesus monkey began shortly after Scoville and Milner (1957) reported that amnesia was produced by surgical removal of the hippocampus and other structures in the...

Dissociation of motor hyperactivity and spatial memory deficits by selective hippocampal lesions in the neonatal rat.
September 22, 1994... INTRODUCTION The role of the hippocampal formation appears to be related to the acquisition of new memories (e.g., O'Keefe & Nadel, 1978; Olton, Becker, & Handelman, 1979; Gray & McNaughton, 1983; Nadel & Zola-Morgan, 1984; Eichenbaum, Otto, &...

Temporal integration in sensorimotor synchronization.
September 22, 1994... INTRODUCTION In various experimental paradigms, integration limitations of central timing mechanisms, as well as temporal segmentation of different human activities, have been observed many times (for an earlier review see Poppel, 1978). The...

Learning a body-centered representation of a three-dimensional target position. (Neural Representations for Sensorimotor Control, part III)
September 22, 1994... SPATIAL REPRESENTATIONS FOR THE NEURAL CONTROL OF FLEXIBLE MOVEMENTS This article describes neural network models of how the brain learns spatial representations with which to control sensory-guided and memory-guided eye and limb movements....

A model of the learning of arm trajectories from spatial deviations.
September 22, 1994... INTRODUCTION Experimental observations of human unconstrained point-to-point reaching movements have noted that several aspects of movements tend to remain invariant, despite variations in movement direction, movement speed, and movement...

Mechanisms of spatial attention: the relation of macrostructure to microstructure in parietal neglect.
September 22, 1994... INTRODUCTION One of the best-known findings in cognitive neuropsychology concerns the "disengage" deficit that follows unilateral parietal damage. In an elegant series of studies, Posner and his colleagues have shown that parietal-damaged...

ERP evidence for a shifting attention deficit in patients with damage to the cerebellum. (event-related potentials)
September 22, 1994... INTRODUCTION Although the cerebellum is most commonly associated with motor control, recent studies have shown that patients with damage to the cerebellum can have deficits in intellectual functioning, visuospatial operations, planning, and...

Endogenously generated and visually guided saccades after lesions of the human frontal eye fields.
September 22, 1994... INTRODUCTION The frontal lobes are the latest structures to develop both phylogenetically and ontogenetically: Their development is most advanced in the human brain and their myelinization is not complete until long after birth. They are...

A Dynamic Systems Approach to Development: Applications.
September 22, 1994... Reviewed by Gyorgy Benedek Developmental scientists have always been receptive to dynamic systems because they come face to face with complexity, nonlinearity, and context dependency every day. The works of scientists from Werner and von...
