Lesions of the superior temporal cortical motion areas impair speed discrimination in the macaque monkey.

@article{citeulike:2799001, abstract = {The effects of circumscribed lesions of the superior temporal cortical motion areas on speed discrimination were tested in three macaque monkeys using both moving random-textured patterns and moving bars. The lesions, which included the middle temporal visual area, the adjacent medial superior temporal visual area and the fundus superior temporal visual area, produced a severe and lasting deficit in speed discrimination when tested with the random patterns. In contrast, deficits were smaller when tested with moving bars. Control lesions of the inferior temporal cortex in two monkeys had little effect on speed discrimination. There was no clear deficit following inferior temporal or superior temporal sulcus lesions on a vernier acuity task. These experiments indicate that the middle temporal and adjacent areas play a crucial role in speed discrimination and that lesion effects depend on the cues available to the animals.}, address = {Laboratorium voor Neuro- en Psychofysiologie, KU Leuven, Medical School, Belgium.}, author = {Orban, G.
