Abstract

In this chapter, we describe the visuotopy of the pulvinar subdivisions P1, P2, and P4. In all primates, P1 colocalizes with the chemoarchitecturally defined PI and a small portion of PL. The peripheral visual field is represented anteriorly in the medial portion of PI, while central vision is represented more posteriorly in the medial portion of PL. The vertical meridian representation is located on the lateral edge of P1, while the horizontal meridian is represented obliquely from the lateral to the medial extent of P1. The upper visual field is represented ventrally, while the lower field is located dorsally. P2 has only been described in the macaque monkey. It contains a representation of the peripheral visual field, located in its anterior portion, and of the central field, which is located in posterior PL. P4 has a complex topographic arrangement. The representation of the vertical meridian is located on the dorsal edge of P4, while the representation of the horizontal meridian divides P4 into dorsal and ventral portions.

Pulvinar投影区的视觉地形。

在本章中，我们描述了枕侧细分P1, P2和P4的视觉解剖。在所有灵长类动物中，P1与化学建筑学定义的PI和一小部分PL共定位。外围视野在PI的内侧前部表示，而中央视野在PL的内侧部分更后方表示。垂直子午线表示位于P1的外侧边缘，而水平子午线表示从P1的外侧到内侧倾斜。上视野位于腹侧，下视野位于背侧。P2只在猕猴中被描述过。它包含位于其前部的外围视野和位于后PL的中央视野的表示。P4具有复杂的地形安排。垂直子午线的表示位于P4的背缘，而水平子午线的表示将P4分为背部和腹部。

期刊介绍： "Advances in Anatomy, Embryology and Cell Biology" presents critical reviews on all topical fields of normal and experimental anatomy including cell biology. The multi-perspective presentation of morphological aspects of basic biological phenomen in the human constitutes the main focus of the series. The contributions re-evaluate the latest findings and show ways for further research.
