“…Behaviorally, 3-month-old rats with one eye removed at birth (OEBs) can relearn a black-white (BW) discrimination faster than those rats with one eye removed at 13 weeks of age (OETs), when relearning is initiated 10 days after lesions of the visual cortex contralateral to the remaining eye (CT visual cortex). In this case the CT visual cortex lesions are made the day following the completion of original learning (Ikeda, Sakai, & Yagi,1988;Ikeda, Sakai, & Yagi, 1992;Ikeda, Yagi, & Sakai, 1983;Sakai, Ikeda, & Yagi, 1991;Sakai, Ikeda, & Yagi, 1996;Yagi & Sakai, 1979;Yagi, Sakai, & Ikeda, 1989). This "faster" relearning phenomenon of OEBs is considered to be a behavioral expression of the above mentioned reorganization in the visual system.…”
