We describe the development of a computer-generated arena within which one can study human place learning by asking subjects to locate an invisible target. A series of studies demonstrate that such learning is based on acquiring knowledge about the spatial relations among the distal cues presented in this arena. We show that (1) the presence of proximal(More)
We compared five indices of brain structure between two groups of schizophrenics, namely, those with high and normal levels of antibody in the serum to herpes virus. Eleven 'immuno-positive' and 21 'immuno-normal' subjects obtained from a concomitant study of serum IgG antibody to viruses underwent magnetic resonance imaging (MRI) utilizing a 1 Tesla magnet(More)
Intracranial, dural-based neoplasms will not infrequently invade adjacent venous sinuses. Therefore, the preoperative diagnosis of venous invasion is important, as it will alter the surgical approach to the lesion. Magnetic resonance imaging is a noninvasive means of visualizing the cerebral venous sinuses. The preoperative diagnosis of venous thrombosis(More)
