Check it out! A person in the 70's in United States wants to know, "what does a synapse look like?"
Here's an answer:
Synapses are created by appendages from each neuron in the synapse, which reach out to each other and ALMOST touch, like a high-five right before impact. Read More
A synapse is the site of communication between neurons. Each neuron has an appendage extended semi-permanently to the other neuron, but they don't quite touch. The small space between them is called the synaptic cleft. One neuron releases chemicals called neurotransmitters and receptors on the other neuron bind them. This binding causes the second neuron to do various things depending on what kind of a neuron it is, such as sending electrical signals to a neuron downstream of itself. What about "semi-permanent"? For the most part in humans, neurons don't regenerate, but they CAN grow new synapses during learning and get rid of unused synapses ("pruning").
