来自海马下托复合体皮质投射神经元轴突终末，在丘脑前核与投射至海马下托皮质的神经元树突形成非对称性轴-树突触。

In anterior thalamic nucleus corticothalamic projection neuron terminals form asymmetric synaptic contacts with HRP-labelled thalamocortical projection neurons by axo-dendritic synapses.

此外，SP阳性轴突末梢还可与NT阳性神经元的树突棘形成对称性轴-棘突触及与NT阳性轴突形成对称性轴-轴突触。

In addition, SP-positive axonal terminals established symmetric axospinous synapses with NT-positive dendritic spines, and axo-axonic synapses with NT-positive axons.

This infinitesimal gap-- and this gap is known as a synapse-- and what happens is when a neuron fires, an axon sends chemicals shooting through the gap.

这个极小的缝隙,这个缝隙就叫做突触,当神经元产生神经冲动后,轴突会释放出能够穿透缝隙的化学物质

When an action potential comes down this pre-synaptic axon, when it reaches this point here, it sets off the process of these vesicles dumping their content into the synaptic cleft.

当动作电位到达轴突的突触前膜时,当到达这一点时 小泡就将其内含物,排放到突触间隙中去

another thing that you'd find if you looked inside the axon terminals of any of these pre-synaptic membranes, you'd find lots of vesicles or some membrane bound compartments that contain special chemicals called neurotransmitters.

如果你仔细观察,突触前膜的轴突末梢内部,你会发现很多小泡,即膜包被的结构,包含有称为神经递质的特殊化合物
