There is no clear evidence on which we can separate the mind from the brain; they appear to develop together and to disintegrate together. Cell theory: all tissue is composed of microscopic units called cells . Rat hippocampus (golgi drawing: golgi stain: cell body (soma)/perikaryon, perikaryon = central region containing nucleus, golgi"s drawings away showed neurons in a reticulum (network), hence reticular theory . The principle that individual neurons are the elementary signaling elements of the nervous system. The neuron doctrine: cajal"s contribution, neural circuitry, neurons communicate by contact, not continuity, neuron doctrine, neurons adhere to cell theory, use of golgi stain. Nissl stain does not produce much detail about the structure of the neuron. Stains rer in cell body and dendrites. Facilitates the study of cytoarchitecture in the.
