In This Issue.
September 1, 1999... You Sound A Little Skinny These Days Fusing multiple sensory modalities to recognize objects is an obvious ecological necessity. Giard and Peronnet (p. 473) measured ERPs on subjects picking out slightly distorted circles and/or slightly...

Auditory-Visual Integration during Multimodal Object Recognition in Humans: A Behavioral and Electrophysiological Study.
September 1, 1999... INTRODUCTION Since the early formal description of our sensory organs by Aristotle about 350 A.D., philosophers and scientists have kept on questioning how individuals achieve perceptual experience of the surrounding world events. Put in...

Activation of Cortical and Cerebellar Motor Areas during Executed and Imagined Hand Movements: An fMRI Study.
September 1, 1999... INTRODUCTION The question of what extent imagery and perception share the same neuronal substrates or if they are based on completely different neuronal mechanisms such as abstract, postperceptual representations, has been an ongoing...

Residual Vision in a Subject with Damaged Visual Cortex.
September 1, 1999... INTRODUCTION A postgeniculate lesion of the visual system, in the optic radiation or striate cortex, causes complete blindness in the area corresponding retinotopically to the neural damage (Grusser & Landis, 1991; Holmes, 1918; Inouye,...

Aging and Recognition Memory: Changes in Regional Cerebral Blood Flow Associated with Components of Reaction Time Distributions.
September 1, 1999... INTRODUCTION Comparison of young and older adults' performance on memory tasks frequently indicates age-related decline (Craik & Jennings, 1992; Light, 1991; Smith, 1996). The magnitude of this decline varies as a function of task and...

Interindividual Variation in Human Visual Performance.
September 1, 1999... INTRODUCTION Although humans differ greatly in their talents and abilities, it is unclear how these idiosyncrasies are instantiated in the nervous system. One possibility is that quantitative differences in the amount of neural circuitry...

Semantic Cortical Activation in Dyslexic Readers.
September 1, 1999... INTRODUCTION The functional anatomy of impaired reading in developmental dyslexia is still poorly known. Previous imaging studies have found differences between normal and dyslexic readers in the activation of various cortical areas....

Spatio-Temporal Prediction Modulates the Perception of Self-Produced Stimuli.
September 1, 1999... INTRODUCTION Our sensory systems are constantly bombarded by a multitude of sensory stimuli, from which we must extract the few stimuli that correspond to important changes within the environment. One class of stimuli that are in most...

Do Deaf People See Better? Texture Segmentation and Visual Search Compensate in Adult but Not in Juvenile Subjects.
September 1, 1999... INTRODUCTION One of the most fascinating outcomes of modern cognitive neuroscience is the finding that cortical representations can be remodeled as a result of unusual environmental demands (Recanzone & Merzenich, 1993). In addition to the...
