本实验观察了电刺激23只猫动眼神经核平面和滑车神经核平面中脑中央灰质(以下简称中央灰质)引起的发音、情绪行为以及心电、血压,呼吸和脑电等变化、并用辣根过氧化物酶(HRP)技术研究了其传入连接。 实验结果表明,刺激猫中央灰质嘴尾侧发音区均能引起发音及瞬膜收缩、扩瞳、伏耳、发“呋呋声”等一系列情绪行为变化,同时伴有心律紊乱、血压升高、呼吸速率和幅度的改变及脑电的去同步化。在慢性实验动物,还可引起环形运动和逃跑反应。刺激非发音区不仅不能引起发音,而且也不能引起明显的情绪反应。HRP研究表明,中央灰质咀尾侧发音区传入连接相类似,均主要接受同侧下丘脑脑内侧核、背侧区、前区、外侧区、后区、中脑黑质、楔状核、注射部位不同平面的中央灰质及扣带回、边缘前区的传入、也接受下丘脑穹窿周围区、室周区、弓状核、视前区及不定带、前斯(Sylvianus)氏回、乙状回,楔状下核等的投射。但在接受投射密度上,中央灰质的嘴侧多于尾侧。中央灰质内侧核非发音区,背外侧非发音区,发音区(腹外侧)传入连接互不相同。内侧核非发音区几乎均等地接受下丘脑和端脑的传入,而很少接受中脑的投射;背外侧非发音区几乎均等地接受下丘脑和中脑的传入,而接受端脑的投射甚少;发音区主要接受下丘脑的传入,而接受端脑?
In this experiment, we observed the changes of the electrocardiogram, blood pressure, respiration, and EEG caused by the electrical stimulation of the plane of the oculomotor nerve nucleus of 23 cats and the plastid central gray matter (hereinafter referred to as the central gray matter) of the trochlear nerve nucleus. Root penetration peroxidase (HRP) technique was used to study its afferent attachment. The experimental results show that stimulating the tail of the cat central gray mouth pronunciation area can cause phonetic and instantaneous membrane contraction, dilation, volt, hair “furosemide” and a series of emotional changes in behavior, accompanied by heart rhythm disorders, elevated blood pressure , Changes in respiration rate and amplitude, and desynchronization of EEG. In chronic laboratory animals, can also cause circular motion and escape response. Stimulation of non-pronunciation area not only can not cause pronunciation, but also can not cause significant emotional reaction. HRP study showed that the central gray matter Tsui pronunciation of the tail pronunciation of the connection area similar to the connection, are mainly accepted ipsilateral hypothalamic medulla, dorsal, anterior, lateral, posterior, midbrain substantia nigra, wedge nucleus, injection Central Plains of different parts of the plane and the cingulate gyrus, the front edge of the incoming, but also accept the surrounding hypothalamic vault, ventricular zone, arcuate nucleus, preoptic zone and the zone, the former Sri Lanka (Sylvianus) back, B Shaped back, wedge-like nucleus projection. However, in receiving the projection density, the central gray matter more than the tail side of the mouth. Central gray matter of the non-pronunciation area of the medial nucleus, dorsolateral non-pronunciation area, pronunciation area (ventral) into the connection different from each other. The medial nuclear non-utterance zone accepts hypothalamus and telencephalon affections almost equally but seldom accepts midbrain projection; dorsolateral non-aural areas receive hypothalamus and midbrain affections almost equally and telencephaloceles Little projection; pronunciation area mainly accept the hypothalamus, while accepting the telencephalon?
