Document Summary
Neuroscience: some neuroscientists work in the space where psychology and neuroscience intersect. Each of the 100 billion neurons are organized into signaling pathways to communicate via synaptic transmission. A typical neuron contains two distinct zones: receptive zone designed to pass on signals to other cells. Made up of dendrites branching out from the cell body. Begins with the cell body; cell body contains most of the vital organelles which keep the cell functioning. Branching from the cell body are a number of projections called dendrites which look a lot like the long, stretching branches of a tree. Dendrites reach out to other neurons and receive signals to be relayed through the dendritic branch to the cell body, where some signals will go on to be conveyed down the axon. Once a signal is received in the receptive zone of the neuron, it is passed down a long fiber called the axon (can vary in length)
