In Blakemore and Cooper's (1970) study of early visual experience, which of the following describes both a behavioral and a neurophysiological finding for the kittens reared in an environment containing only horizontal stripes?
They failed to show a startle response when a vertical rod was shaken in front of them, and microelectrode recordings revealed an absence of neurons in the visual cortex with preferred orientations within 45∘45^\circ45∘ of the vertical.
They were unable to negotiate horizontal barriers placed in their path, and microelectrode recordings revealed that 100%100\%100% of the cells in their visual cortex responded exclusively to vertical orientations.
They lacked pupillary light reflexes in both eyes, and microelectrode recordings showed complete structural degeneration of the optic nerve fibers leading to the lateral geniculate nucleus.
They showed a preference for navigating towards vertically oriented objects, and microelectrode recordings showed that their visual cortex had completely reorganized to process somatosensory feedback.
