杏仁体内输入的目标是灵长类动物中的多巴胺和GABA神经元:从树突和索马的角度看
bioRxiv : the preprint server for biology
|January 31, 2024
概括
杏仁体的中央核 (CeN) 均地与VTA中的多巴胺 (DA) 和GABA神经元接触,这表明位置和细胞类型不会影响输入. 这种统一性,加上不同的DA:GABA比率,塑造了积极的行为.
科学领域:
- 神经科学是一个神经科学.
- 细胞生物学 细胞生物学
- 神经解剖学是一个神经解剖学.
背景情况:
- 杏仁体的中央核 (CeN) 通过多巴胺 (DA) 系统输出调节动机学习和行为.
- 灵长类动物的CeN终端准特定的中脑区域:准肌色素核 (PBP,A10) 和后脑脑野 (A8).
结论:
- 杏仁核内核投影表现出惊人的统一性,表明神经递质表型和中脑位置并不决定接触的可能性.
- 这种统一的输入,加上DA:GABA细胞比率的区域差异,可能是激发行为的各种影响的基础.

Functional Brain Systems: Limbic System
2.8K
The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep brain...

Diencephalon: Thalamus and Information Relay
1.6K
The thalamus, often called “the gateway to the cerebral cortex,” is vital in processing and directing sensory and motor signals throughout the brain. Almost all inputs destined for the cerebral cortex, except for olfactory signals, are relayed through the thalamus. The thalamus is a sophisticated relay station, channeling information from various brain regions to the cerebral cortex, as well as a filter, prioritizing certain signals over others based on current physiological...

Diencephalon: Anatomical Regions
2.0K
The diencephalon, etymologically translated as 'through brain,' plays an integral role as the conduit between the cerebrum and the vast extent of the nervous system. However, the olfactory system is an exception, as it interfaces directly with the cerebrum. The diencephalon, deeply ensconced beneath the cerebrum, primarily consists of three paired structures — the thalamus, hypothalamus, and epithelamus. It also includes accessory structures such as the subthalamus, which houses the...
