背景情况:

人类的记忆检索可以由内部驱动,与动物模型不同,动物模型通常依赖于外部线索和行为.
现有的动物模型很难将与记忆本身有关的神经活动与线索或行为相隔开来.

研究的目的:

为了调查与记忆检索相关的神经活动是否可以在没有感官线索或行为输出的动物中产生.
探索海马体中远程空间表示的故意参与.

主要方法:

开发了一种神经反系统,以奖励大鼠远程海马位细胞表现的表达.
利用了一种系统,允许老鼠学会自愿生成特定的空间表示.

主要成果:

老鼠成功地学会了产生特定的空间表示,通常直接针对实验者定义的位置.
证明动物可以故意参与遥远的地方细胞表征.

结论:

这项研究建立了一种新的方法来研究动物的记忆检索,而不依赖于外部触发器或行为.
这些发现为直接调查自愿记忆回忆的神经机制铺平了道路.

Neural Regulation

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Feedback Regulation of Calcium Concentration

Feedback Regulation of Calcium Concentration

Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...
