Neural correlates of hysterical blindness.
The neural mechanisms underlying conversion disorders such as hysterical blindness are at present unknown. Typically, patients are diagnosed through exclusion of neurological disease and the absence of pathologic neurophysiological diagnostic findings. Here, we investigate the neural basis of this disorder by combining electrophysiological (event-related potentials) and hemodynamic measures (fu...

The story is centered around the transient visual loss of a 29-year-old Austrian messenger of the 16th Bavarian Infantry Regiment. His name: Adolf Hitler.
متن کاملSensitivity to Light in a Case of Hysterical Blindness Studied by Reinforcement-Inhibition and Conditioning Methods *
A previous study of sensitivity to light in a case of hemianopsia following surgical resection of one occipital lobe indicated absence of reflex sensitivity in the blind area as measured by the reinforcement-inhibition effects of light on the eyelid reflex to sound.2 It seemed of methodological interest to investigate similarly a case in which there was a functional blindness, and to compare th...
متن کاملFeature study of hysterical blindness EEG based on FastICA with combined-channel information.
BACKGROUND An appropriate feature study of hysteria electroencephalograms (EEG) would provide new insights into neural mechanisms of the disease, and also make improvements in patient diagnosis and management. OBJECTIVE The objective of this paper is to provide an explanation for what causes a particular visual loss, by associating the features of hysterical blindness EEG with brain function....
