Impaired stereoscopic detection thresholds after left or right temporal lobectomy

Neuropsychologia
A Ptito, R J Zatorre

Abstract

The present study assessed global stereopsis as measured by random dot stereograms (RDS). Single stimuli were presented in order of increasing binocular correlation (40-100%) making it progressively easier to perceive the figures in depth, and then the same set of stimuli was presented in reverse order. The subjects tested included 50 patients with unilateral temporal-lobe lesions, 11 patients with right frontal-lobe lesions and 18 normal control subjects. Results indicate that either right or left temporal lobectomy leads to a higher than normal detection threshold for RDS. In contrast, right frontal lobectomy did not have a significant effect compared to the normal control subjects. All subjects were able to perceive correctly the figures at 100% binocular correlation. The results are interpreted in terms of a possible contribution of the inferior temporal cortex to global stereopsis.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
