Document Summary
The electrical and chemical activities of neurons are the starting point of all behaviour, thought, and emotion. Approximately 100 billion cells in your brain perform a variety of tasks to allow a person to function. Neurons are cells in the nervous system that communicate with one antoher to perform information-processing tasks. In the 1800s scientists studied the mechanics of limbs, lungs and livers in order to study the harder-to-observe brain. Believed the brain was composed of many lattices of fine threads. Late 1880s spanish physician, santiago ramon y cajal found that the cells came in different shapes and sizes. Cajal concluded that neurons are the information-processing units of the brain. Functions such as protein synthesis, energy production, and metabolism. Contains a nucleus; this structure houses chromosomes that contain your dna. Surrounded by a porous cell membrane that allows molecules to flow in and out (there are 2 types of specialized extensions of the cell membrane)
