Disturbances of Spatial Orientation and Visual Attention, With Loss of Stereoscopic Vision

Abstract

The patient, Private W. F., aged 30, had been a circular saw operator and was an intelligent and fairly well educated artisan. He was wounded May 19, 1918, probably by a machine gun bullet, but as he became at once unconscious and remained so for several days, it was impossible to obtain an accurate history. He was admitted on the same day to a casualty clearing station with a perforating wound of the head ; both entrance and exit wounds were excised, fractured bone removed, softened and extruding brainmatter evacuated, and the scalp excisions were then sutured. The patient, however, remained still unconscious, vomited repeatedly and had several epileptiform fits which affected chiefly his left side. On the sixth day he asked for food, and it was recorded in his notes that he could then see.

Anterior-Posterior Gradient in the Integrated Processing of Forelimb Movement Direction and Distance in Macaque Parietal Cortex

“…Article ll OPEN ACCESS with the frontal cortex (Fabbri et al, 2012). The involvement of medial PPC in the encoding of reach distance was first reported in a human case study (Holmes and Horrax, 1919). These observations are in agreement with present results and support a common framework of depth and direction processing in human and nonhuman primates.…”

A world unglued: simultanagnosia as a spatial restriction of attention

“…It has been argued that simultanagnosia is a misnomer, because “agnosia” implies a failure of recognition whereas patients with simultanagnosia can typically recognize the objects that they see (Rizzo and Robin, 1990). This is consistent with the conceptualization of simultanagnosic patients as “object-detectors” (Holmes and Horrax, 1919; Baylis et al, 1994). Indeed, there is some evidence of priority for object selection over spatial selection in simultanagnosia, implying preservation of the former and deficits in the latter.…”
