A Cat's Left Eye Was Covered During the Critical Period

Short Answer

A cat's left eye was covered during the critical period of development after eye opening. At the age of 6 months, a radioactive tracer molecule was injected into the right eye and allowed to reach the primary visual cortex. The cortex was then sectioned and subjected to autoradiography to reveal the ocular dominance columns. Which stripes would you expect to be wider: the dark stripes due to radioactivity (D) or light stripes (L)? Write down D or L as your answer.
