Synapse - Wikipedia
In the nervous system, a synapse[ 1 ] is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell. Synapses can be chemical or electrical.

2023年3月27日 · The places where neurons connect and communicate with each other are called synapses. Each neuron has anywhere between a few to hundreds of thousands of synaptic connections, and these connections can be with itself, neighboring neurons, or neurons in other regions of the brain. A synapse is made up of a presynaptic and postsynaptic terminal.
Sending Information: Synapses and Neurotransmission - BrainFacts
2022年11月30日 · Neurons pass information to each other in a process called neurotransmission. Signals are passed from one neuron to the next at junctions called synapses. In most circuits, a synapse includes the end of an axon, the dendrite of an adjacent neuron, and a space between the two called the synaptic cleft.

2024年9月12日 · Synapses connect neurons and help transmit information from one neuron to the next. They pass sensory signals such as pain or touch from the nervous system to the brain, and they help you move the muscles in your body. They are also involved in memory processing and storage. There are two main types of synapses:
Synaptic Signaling in Learning and Memory - PMC - National …
Learning and memory require the formation of new neural networks in the brain. A key mechanism underlying this process is synaptic plasticity at excitatory synapses, which connect neurons into networks. Excitatory synaptic transmission happens when glutamate, the excitatory neurotransmitter, activates receptors on the postsynaptic neuron.
