Dopamine rushes, withdrawals, and detoxes are trending among wellness gurus online. But experts say the science behind the ...

To do this, they use neurotransmitters. At the end of each neuron is a tiny gap called a synapse, and to communicate with the next cell, the signal needs to be able to cross this small space.

Some types of molecules (excitatory neurotransmitters) promote the activation of a neuron, while others (inhibitory neurotransmitters) reduce activation. Key neurotransmitters include the following: ...

Neuron Function Synapses Neural synapses are junctions between neurons that permit neural communication. Synapses come in two different forms: chemical and electrical. 2 Chemical synapses communicate ...

There are two types of removal: Re-uptake – the neurotransmitter is reabsorbed back into the presynaptic neuron and restored inside a vesicle ready to be used again. For example, noradrenaline.

“Fusion competent synaptic vesicles persist upon active zone disruption and loss of vesicle docking,” Neuron, 91:777-91, 2016. Hair trigger Neurons send each other signals by firing neurotransmitters ...

This results in enough neurotransmitter being diffused across the synaptic cleft to trigger the impulse in the postsynaptic neuron. This process is called summation.
