Document Summary
Loss of neurons in specific brain areas (ex. More than 15,000 nova scotians are now living with alzheimer"s. Yet most neurons have a number of common features. All these different neurons from different areas of the nervous system still have the three common features. Good understanding of neuronal diversity established by the early 20th century. Pioneering cell-staining method by introduced by camillo golgi and utilized by: ramon y cajal. Gogi stain: tissue washed with silver salts, a few neurons take up the silver and are stained black (a and b) Only one neuron out of every thousand or so will pick up the stain while the others won"t. Cajal thought that they were individual cell like other cells in the body but golgi didn"t agree. More recently developed fluorescent dyes c can be injected into individual neurons using specialized equipment. Dendrites and axons and synapses allow neurons to perform their principle function.
