Document Summary
The mind is seen as a separate entity existing outside of our biology, yet in control of our actions and thoughts. Neurons are cells that are specialized for communication: each neuron in the brain is organized into signaling pathways to communicate via synaptic transmission. The cell body contains most of the vital organelles, which keep the cell functioning. Branching form, the cell body are number of projections called dendrites which look a lot like the long, stretching branches of a tree. The terminal boutons reach out and make connections with receptive zone of nearby neurons to transmit the signal further: this reception and transmission of each neuron builds a network. Each neuron can receive inputs from thousands of other neurons through their dendrites and terminal boutons to form complex network of information transfer. If neurons are the star players, then the glial cells are the important supporting cast.
