什么是神经系统?
The nervous system is the collection of specialized cells responsible for maintaining an organism’s internal environment and coordinating the…
副交感神经系统
The parasympathetic nervous system is one of the two major divisions of the autonomic nervous system. This parasympathetic system is responsible…
交感神经系统
The sympathetic nervous system—one of the two major divisions of the autonomic nervous system—is activated in times of stress. It…
血脑屏障
The blood-brain barrier (BBB) refers to the specialized vasculature that provides the brain with nutrients in the blood while strictly regulating…
神经元结构
Neurons are the main type of cell in the nervous system that generate and transmit electrochemical signals. They primarily communicate with each…
突触
Neurons communicate with one another by passing on their electrical signals to other neurons. A synapse is the location where two neurons meet to…
胶质细胞
Glial cells are one of the two main types of cells in the nervous system. Glia cells comprise astrocytes, oligodendrocytes, microglia, and…
静息膜电位
The relative difference in electrical charge, or voltage, between the inside and the outside of a cell membrane, is called the membrane potential.…
动作电位
Neurons communicate by firing action potentials—the electrochemical signal that is propagated along the axon. The signal results in the…
增强效应
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in…
长期抑郁
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in…
免疫组化可视化小鼠肠神经系统的发展
The enteric nervous system is formed by neural crest cells that proliferate, migrate and colonize the gut. Following colonization, neural crest cells…
三维组织工程化排列的星形胶质细胞网络, 以概括发展机制和促进神经系统再生
Neurotrauma and neurodegenerative disease often result in lasting neurological deficits due to the limited capacity of the central nervous system…
一种研究外周和中枢神经系统 Neuroregeneration 的<em>果蝇体内</em>损伤模型
The regrowth capacity of damaged neurons governs neuroregeneration and functional recovery after nervous system trauma. Over the past few decades,…
