Cytochemistry of synaptosomes
TLDR
The decrement in density of the synaptic Cleft, demonstrated microdensitometrically, suggested that at least some of the sialic acid freed from synaptosomes by incubation in neuraminidase is located extracellularly, within the synaptic cleft.About:

TL;DR: The present review will discuss the glia-derived glycoproteins and CSPGs of the perisynaptic ECM, their neuronal and glial receptors, and in vitro assays to test their physiological functions in the framework of the synapse, the pivotal element of communication in the central nervous system.

ticles Effect of Neonatal Malnutrition on Developing Cerebrum: I. Microchemical and Histologic Study of Cellular Differentiation in the Rat
TL;DR: The effect of undernutrition on the development of cerebral cortex is better studied in suckling rats during the first three postnatal weeks when growth of cortex and cytoplasmic differentiation of neurons is maximal.

Enzymatic digestion of synaptic ribbons in amphibian retinal photoreceptors.
TL;DR: It is concluded that the ribbons probably do not contain appreciable amounts of DNA or RNA, and may be composed, at least in part, of a protein or polypeptide which is rich in aromatic amino acids.

The thiobarbituric acid assay of sialic acids.
TL;DR: This chapter discusses the different aspects of thiobarbituric acid assay of sialic acid, which is suitable for measuring the release of bound sialoic acid by sialidase and hydrolysis of sIALic acid-containing material must be carried out for the measurement of total sialsic acids.

The formation of synaptic junctions in developing rat brain: A quantitative electron microscopic study
TL;DR: It was found that a sharp increase in the number of synaptic junctions occurs in rat cortex (molecular layer) during the 3rd and 4th postnatal weeks, and it is proposed that synapticJunctions evolve through several stages and a tentative morphogenetic scheme is presented.

Electron microscope observations on the carbohydrate-rich cell coat present at the surface of cells in the rat.
A. Rambourg,C. P. Leblond +1 more
TL;DR: Findings indicate that the stained layer is a "cell coat" located outside the plasma membrane, since the cell coat is also stained by colloidal thorium, a technique for detection of acidic carbohydrates, this structure presumably contains not only glycoprotein but also acidic residues.
