在暹罗猫中，先前的研究表明，基因突变导致每只眼睛中的视网膜原纤维（retinogeniculate 纤维）产生于颞视网膜，代表与垂直子午线相邻的同侧视野的 20°，在视交叉中异常交叉，从而终止于错误的外侧膝状核。该异常随后在视觉皮层水平上表达。本文提供的解剖学证据表明，与普通猫相比，“波士顿”品种暹罗猫的连合视觉连接模式也高度异常。
In Siamese cats, previous studies have shown that a genetic mutation causes retinogeniculate fibers in each eye which arise from the temporal retina representing the 20° of ipsilateral visual field adjacent to the vertical meridian to cross aberrantly in the optic chiasm, thereby terminating in the wrong lateral geniculate nucleus. The abnormality is expressed subsequently at the level of the visual cortex. This paper presents anatomical evidence that the pattern of commissural visual connections in the “Boston” variety of Siamese cat also is highly abnormal in comparison to that of ordinary cats.
