Approximately 86 billion neurons in the human brain. http://www.nature.com/scitable/blog/brain-metrics/are_there_really_as_many Structure of neurons: Structure of neurons Neurons function: Neurons function http://www.enchantedlearning.com/subjects/anatomy/brain/Neuron.shtml Imput signal Output signal Integration Synapse Synapse: Synapse Structure of typical neurons: Structure of typical neurons Afferent and efferent: Afferent and efferent http://www.rhsmpsychology.com/Study%20Guides/unit_5_neuroscience_page2.htm Importance of neurons: Importance of neurons Transmit messages in our nervous system (sensory and motor). Neurons stop reproducing shortly after birth Neurotransmitters have been studied quite a bit in relation to psychology and human behavior. What we have found is that several neurotransmitters play a role in the way we behave, learn, the way we feel, and sleep. And, some play a role in mental illnesses.
