They are neurotransmitters. They are sent across synapses from one nerve to another.
SSRIs increase the concentration of serotonin in the gap between the neuron synapses in certain part of the brain. This is the method of action of SSRIs, but WHY does this cause anti-depressant effect, it is still to be found.
neurotransmitter like serotonin, dopamine, or acetylcholine. These are molecules that transmit signals across synapses in the nervous system to regulate various processes such as mood, movement, and memory.
Antidepressants work by increasing the quantity and action of all or some of the neurotransmitters, namely (1)serotonin, (2)dopamine, (3) norepinephrine at the synapses in brain in a person suffering from depression.
There is not just one chemical secreted into synapses (the gaps between neurons); instead, there are many chemicals secreted from the terminal buttons of neurons into the synapses. They are called "neurotransmitters."
There are over 100 different types of neurotransmitters that can be released into synapses, each with specific functions and effects on neuronal communication. Some of the most well-known neurotransmitters include serotonin, dopamine, and glutamate.
MDMA, or ecstasy, affects three neurotransmitters: serotonin, dopamine, and norepinephrine. Studies show that MDMA can damage serotonin containing neurons. "Studies have shown that some heavy MDMA users experience long lasting confusion, depression, and selective impairment of working memory and attention processes."

The synapses take place in the spinal cord
The brain is estimated to have around 100 trillion synapses. These synapses are the connections between neurons that allow them to communicate with each other.
