Document Summary
Today we will consider the biology and neurology of neurons. There are tons of neurons in the brain. They are the basic components that define the limits of our brain. If we knew nothing about how a neuron works we would make different assumptions than what we make today (in regards to how the brain works). The smallest neurons in the brain are in the hypothalamus. The neuron has a dendrite field that picks up information and interpretative field that integrates the information and sends it down. Neurons in the brain can have fast dendrite fields. The shape of the neuron tells us what its function is. Neurons are able to integrate massive amounts of signals into one package. Simple neurons cannot integrate very much because they have a more focused function. Hypothalamic neurons for example tend to be concentrated in nuclei and the nuclei have very specific functions (maintaining of the organism, hormonal levels, ionic levels, etc).
