Function
1. Adjusting the visceral activity
2. Adjusting the sensation information in the central nervous system
in low and other vertebrates, brain The hippocampus structure can accept the effects of various sensory stimuli. In higher mammals, physical, audisitations, and visual impacts can be introduced into the hippocampus; the hippartum front zone of the stimulation of the edge system can increase the pain threshold; stimulate the almond nuclear group to make the knee in the hunter The auditory information is suppressed.
3. Influencing or producing an almond karma of the monkey, cat, dog and other animals, hippocampus, vision, front area, 窿, smelling tuning and partition, Make animals "anger" response or "angry behavior". There is also a research prove that if the buckle is damaged back, it does not hurt the brain's new skin layer, often makes the emotional reaction of the animal or is not easy to appear. The horizon has risen, and there is a "social indifference" or "failing fear" symptoms. At this time, animals are indifferent to the hazardous stimuli that must usually avoid.
After the Cat's almond core, there is a sexual function related to emotional reaction and enhanced sexual response. The almond core of macaques can make its behavior in the position of the ruler from the dominant position in the group life. Clinical studies have shown that after the wounded edge system is more extensive, the patient is extremely vulnerable, and a strong emotional reaction is exhibited in social situations. This is also very similar to the experimental results obtained by using animals.
4. Causes sleep activities
of the edge system in the edge system, the deputy copied skin, the front part of the front, the front of the hypothalamus is part of the sleep activity, these parts Has been collectively referred to as the base of the base. This brain area is stimulated with current, and the animal has a sleep reaction. In this brain, the following levels are cutted, and the insomnia of the rats can be eliminated. Clinical observation demonstrated that due to patients in the base of the brain surgical injury, there is also a serious insomnia symptom.
5. After the study and memory activities
After damage to the bilateral hippocampus, although the animal can establish the operational conditions reflection, and form differential reflection activities to different graphics, The number of training is greatly increased. They are more difficult to establish reflection activity that is stimulated by time intervals, and cannot cultivate conditions of delayed reflection. Animals already have delayed reflection, if they are removed, the delay reflection is not easy to appear, but other conditions reflection are still saved. After the hippocampus is damaged, the animals are enhanced in the surrounding environment. This reaction is difficult to resolve when the newly stimulus repeatedly occurs. This shows that the "memory" capability of animals is damaged. However, for the established conditions, it does not disappear after the hippocampus is damaged, which means that the hippocampus is not a part of the past experience. It is likely that various stimulus information will leave a temporary trace in hippocampus. After its activities, the stimulating information enters long memory.
Edge System Related Anatomical Sex
1878 French scholar Broca Pretty a constant curved brain around the mammaline brain denems is "Legrandlobe Limbigue). This is probably the source of the noun of "edge leaves". General scholars believe that it includes buckle back, sea horses, hippocampal structures, partitions and pearous leaves. Later, the concept of edge leaves gradually expanded, a region similar to the edge leather structure (returned to the rear, island leaf and temporal lobe), and some cortical structures closely related to function and contacts ( , Almond nuclear, hypothalamus, upper hysternet, phenologous nucleus, and central brain, cover, etc.), called edge systems. Edge system cortex is an old part in the process of biological evolution, including an old abundant cortex (such as the ancient cortex, partition and almond nucleus, etc. of hippocampus and almonds) and intermediate cortex (including necoli) Rear, island leaf, temporal pole, buckle, etc.). The blood supply of the edge system cortex is very special, and the blood supply is supplied only by the through arteri and the intravenous vein vein, and the intravenous vein is also injected into the deep vein in the brain. It will be understood from the above anatomical structure. Except for the late malignant tumor, a tumor originating from the system has certain affinity on the original cortical region of the seed system, that is, the tumor is only limited to the original cortical region, and the neighboring new Leather and inner deep structures such as screen cores, shell nuclear, pale balls and decays. The tumor This growth method provides theoretical basis for neurosurgeons to treat tumors, rather than injuries or rarely damage these important structures. This concept is being attached.
