Document Summary
Psychology: the evolution of a science: neurons: the origin of behavior (pgs 78 82) All thoughts, feelings, and behaviors spring from cells in the brain called neurons that take in information and produce some kind of output. Discovery of how neurons function (pg 78) Santiago ram n y cajal (1852 1934) learned of a new technique for staining neurons in the brain, called golgi-stained neurons. Components of the neuron (pgs 79 80) Cajal discovered that neurons are composed of three basic parts: the cell body, the dendrites, and the axon. Cell body is the largest component of the neuron and coordinates functions such as protein synthesis, energy production, and metabolism to occur within it. Also contains a nucleus that houses chromosomes contain dna. Cell body is surrounded by a porous cell membrane allowing molecules to flow in and out of the cell.
