概括
在研究小脑可塑性时,这项研究绘制了灵长类动物的乳腺-卵巢通路. 结果显示,中部下层橄树的标签稀疏,这表明非地形错误编码为saccade适应.
科学领域:
- 神经科学是一个神经科学.
- 大脑小贝的可塑性
- 行为适应 行为适应
背景情况:
- 萨卡德适应模式大脑小脑可塑性.
- 在适应过程中,上层结体-下层橄路径至关重要.
- 之前的灵长类人乳卵管路径研究使用了有限的中央注射.
研究的目的:
- 详细介绍灵长类人造骨-卵巢通路,通过注入前级标记物到各种上层结晶体区域.
- 为了研究的上方结体到中部下层橄的投射模式.
- 为了理解视觉错误信号的神经基质在saccade适应.
主要方法:
- 向标记剂注射到的特定区域.
- 组织学分析以绘制中间下层橄中终端田的地图.
- 标记模式的比较从中央,面向和尾部的上方注射.
主要成果:
- 大型中央注射标记在对侧中间下层橄 (C分区) 中密集的终端场.
- 以前没有观察到的稀疏标签发生在Kooy的背盖上双边,在中间下层橄 (C分区) 中双边.

Association Areas of the Cortex
5.5K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Cranial Bones: Superior and Posterior View
2.4K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Cerebellum: Anatomical Regions
1.8K
The cerebellum, also known as the "little brain," is located in the posterior cranial fossa, inferior to the tentorium cerebelli and dorsal to the brainstem. It plays a significant role in motor control, coordination, and proprioception.
Cerebellar Structure
Externally, the cerebellum features a highly convoluted surface with numerous folia (narrow ridges) separated by shallow sulci (grooves). The cerebellum is divided into two hemispheres by a thin median structure known as the vermis. The...
