The effect of partial covering of the eye on the results of selective deprivation of visual pattern in the fly.

Visual deprivation experiments have demonstrated that the development of pattern discrimination in the fly depends on experience in the early period after emergence. Based on this finding, a behavioral study was done in which flies had their eyes partially covered during selective deprivation treatment. This study demonstrated that several simple visual patterns are mainly identified in a restricted, pattern-specific region of the compound eyes, and also that the effect of visual deprivation is produced in the unilateral compound eye and is not transferred to the contralateral side.
