Welcome to Science With Tal!
In this video, we will cover the group of neurotransmitters: biogenic amines. Biogenic amines include dopamine, norepinephrine, epinephrine, histamine & serotonin (5-HT). In this video, we will cover their respective synthesis pathways and respective postsynaptic receptors. We will also cover where these neurotransmitters are more prominent and what general functions they mediate.
This conversation on neurons in the CNS derives from important concepts that are described in two previous full discussions:
1- To watch the first part (Signal propagation in the Neuron), make sure to go to: • Signal Propagation In ...
2- To watch the second (The Neuromuscular Junction as the model of the chemical synapse) make sure to go to: • Neuromuscular Junction...
