独特的底侧杏仁体 (BLA) 神经元组计划分离大脑目标,揭示行为,注意力和防御的专业电路. 这挑战了以前的BLA连接概念.
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
- 系统神经科学 系统神经科学
背景情况:
- 已知底侧杏仁体 (BLA) 投射到多个大脑区域,影响各种功能.
- 然而,来自BLA神经元的轴突抵押的确切程度仍在争论中.
研究的目的:
- 为了研究底侧杏仁体 (BLA) 神经元的担保模式.
- 为了确定不同的BLA神经元群是否向特定的,不重叠的目标区域发射.
主要方法:
- 利用病毒追踪技术绘制BLA神经元投射图.
- 分析了BLA轴突对各种皮层和皮层下目标的抵押.
主要成果:
- 确定了不同的BLA神经元集群,投射到特定的目标子集.
- 一组针对调节动机行为,注意力,能量恒温和嗅觉的区域.
- 另一个群体的目标是与防御行为有关的皮质下区域.
- 投射到与记忆相关的皮质区域 (海马体,鼻腔皮层) 的BLA神经元显示出有限的附带化.
结论:
- 底侧杏仁体 (BLA) 包含功能上不同的神经元集群,有分支的轴突,主要针对不重叠的大脑区域.
- 这一发现需要对BLA在协调大脑功能和对其目标施加影响方面的作用进行修订理解.

Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
