Christensen discovered a rare birth defect, known as agenesis of the corpus callosum, during a brain scan in the 1980s. Peek was missing the thick bundle of millions of nerve fibers that connects the left and right hemispheres of the brain. 在20世纪80年代进行的一次脑扫描中,Christensen发现了Peek患有一种被称作胼胝体发育不全的罕见的先天缺陷,他的左右脑连接的纤维束缺失了。
