neuron; conduction of the action potentialIn a myelinated axon, the myelin sheath prevents the local current (small black arrows) from flowing across the membrane. This forces the current to travel down the nerve fibre to the unmyelinated nodes of Ranvier, which have a high concentration of io...

Transmitter molecules are released through the presynaptic region into the synaptic cleft. These molecules will diffuse over this narrow space and reach receptors specific to the transmitter at the postsynaptic membrane (of another neuron or an effector cell). The activation of the postsynaptic ...
However, whether such correlations can survive in a high-temperature biological environment to propagate through a neural network is still an open question. In this work, we examine one of the first steps in this process, the diffusion of neurotransmitters through the synaptic clef...
问答题 In neuron-to-neuron synaptic transmission, when a nerve impulse reaches the terminal bouton of the presynaptic neuron, it causes the terminal bouton to secrete ( ) into the synaptic cleft.(0.5分) 参考答案:neurotransmitters 点击查看答案...
英文: To later shut down the signal, the VTA neuron removes the dopamine from the synaptic cleft and repackages it to be used again as needed. 中文: 之后为了停止讯号的传送,VTA神经元会收回突触间隙的多巴胺,并重新组装以备再度需要的时刻。更详细... ...
Neurotransmitters released from the presynaptic cell rapidly populate the synaptic cleft and bind to receptors on the postsynaptic neuron. The binding of neurotransmitters instigates chemical changes in the postsynaptic neuron, such as opening or closing ion channels. This, in turn, alters the membrane ...
The meaning of SYNAPTIC VESICLE is a small secretory vesicle that contains a neurotransmitter, is found inside an axon near the presynaptic membrane, and releases its contents into the synaptic cleft after fusing with the membrane. How to use synaptic ve
In contrast, incubation with 40 μM d-TC for 5 min completely blocked the ability of presynaptic stimulation to elicit action potentials (n = 3 cells; data not shown). In no case were multiple action potentials triggered in the ganglionic neuron by the single brief stimulation of the ...
