包括中脑腹侧被盖区(蔡翘)[VTA(Tsai)]在内的许多中脑核群,属于旁中央中脑区。因其与边缘系统及下丘脑有着密切的交互连接,因此也被称为边缘中脑区。由于边缘系统及下丘脑对于机体的基本行为及调节活动的重要性,以及中脑在脑中处于“峡部“地位,研究边缘中脑区的各个方面,显然是十分重要的。近几年来我们对旁中央中脑区的电生理作了以下两方面的工作。 A number of mesencephalic nuclei, including ventral tegular area (Tsai) [VTA (Tsai)], belong to the paracentral midbrain area. Because of its close relationship with the limbic system and the hypothalamus, it is also called the marginal mesolimbic region. Due to the importance of the limbic system and the hypothalamus to the basic behavior of the body and its regulatory activity, and the fact that the midbrain is “isthmially” in the brain, it is clearly important to study various aspects of the marginal mesolimbic zone. In recent years, we made the following two aspects to the electrophysiology next to the central midbrain area.
