A physiological and behavioural study in cats of the effect of early visual experience with contours of a single orientation.

摘要: 1. Three kittens were reared in visual environments that consisted of stripes at one three orientations - horizontal, right oblique, or left oblique. Two additional cats as controls. One these matured viewing and oblique on alternate days. The other experienced a normal environment. 2. Following the completion rearing, after several weeks experience, behavioural testing stripe-reared animals demonstrated deficit acuity for which not present early No comparable emerged either control cats. 3. 1-3 years further, normal, each was shipped separately to California where single units recorded from area 17 cortex an effort made guess history animal unknown experimenters. Cell samples experimental cat allowed physiologist their experience correctly. orthogonal sets days bias horizontal contours his cell sample. In contrast cats, about 80% are binocular, only 30% cells could be influenced by both eyes.
