Document Summary
Things to consider: biology, where you grew up, who raised you, your experiences. Neuron: cells of brain and nervous system designed to quickly send and receive signals. Synapse: small gaps between neurons that signals submit across. Glia: cells that provide structure for the brain and support the neurons. Help manufacture myelin, distribute nutrition, minimize toxins and dispose of dead neurons. Neurotransmitters: chemicals that assist in transfer of messages across synapses from one neuron to another. The early development of neurons is related to gene expression and regulation (mostly. On overabundance of neurons and synapses are produced during early development. At birth, children have more synapses and neurons than the adult brain. Neurons with axons that make the best connections that are active survive. In general, the bigger the brain of species, the more intelligent animals of that species are likely to be.
