The Histochemical Study of the Catecholamine Part III The Distribution of Catecholamine Fibers and Serotomin Containing Neurons in the Rat's Hippocampal

The formaldehyde induced fluorescence technique (Falck et al ,. ‘62) allows for the microscopic visualization of interneural monoamines. The recently introduced chloralhydrate-glyoxylic acid-formaldehyde method (Hobara, ‘76) appears to offer an advantageous approach to monoamine tract tracing. The technique allows the important finding that a marked degree of mixing of the various adrenergic components occurs in the central tract in many animal brainds. From this reason, the authors studied for the distribution of catecholamine containing fibers and serotonin containing neurons in the rat's hippocampal formation.
