The Use of Brain Slices,ructure of which had not been extensively disrupted. When we use this technique we assume, or hope, that results obtained may represent actual physiological activities or potentialities of the tissue. The technique has been described and discussed previously in commonly available volumes,. and I sha

DNA Metabolism and Cell Proliferation,h three major techniques: (1) histological and cytological studies of cell division, which in some investigations were coupled with the auxiliary procedure of blocking mitosis with a mitotic poison, such as colchicine; (2) gross and microchemical studies of differences in DNA concentration in the br

Chemistry of Isolated Invertebrate Neurons, systems. Even in the lower invertebrates the degree of organization and differentiation of the nervous system is sufficiently high for the fundamental mechanisms of transmission, conduction, and integration to be studied. However, some scientists still hesitate to compare the properties of neurons

Nuclei,protein synthesis. Nuclei have been isolated from liver, thymus, HeLa cells, and ascites tumors, among others, because these tissues consist mainly of homogeneous cells that are easily disrupted and permit isolation of intact nuclei in good yields. These techniques recently have been reviewed.. Atte

Lysosomes,e lysosome. This organelle has been implicated in a number of physiological and pathological processes and has attracted considerable attention because of the destructive potential of its enzymes. In this chapter we shall briefly survey the current status of lysosomes with particular reference to th

Although mitochondria from neural tissue have certain qualitative differences in their enzymic and chemical constitution from liver and hear

The Synaptosome,nals are torn away from their axons and seal up to form detached particles. to which the name . has been given.. These particles retain the morphological features and, as far as we know, the chemical composition (including the transmitter content) of the intact presynaptic terminal. They can be sepa

Structural Components of the Synaptic Region,entiation for the transmission of nerve impulses. As suggested by Du Bois Raymond in 1877, synaptic transmission may be either chemical or electrical, and both mechanisms have been found to occur in the peripheral and central nervous systems. However, chemical synapses are by far the more common and
