Collection: Brain of the birds (Aves)

Species: Coturnix japonica Temminck et Schlegel, 1849    Aves

Description: Frontal (transverse) celloidin section through a telencephalic hemisphere of a Japanese quail impregnated with silver salts by the Golgi method. Central region of the pallium (M - mesopallium) showing a group of neurons of various types that form one of the numerous multineuron groups of the pallium ("nests"). In addition to the neurons, the multicellular groups include glial cells. The preparation clearly shows several glial cells (presumably the astrocytes - ast). They come in close contact with the neurites and cell bodies of the neurons to form a neuro-glial complex (or using the modern terminology, "the neuro-glial unit"). This emphasizes the important role of glia in the functioning of the nerve centers. The section also shows impregnated blood vessels (bv) and deposits of silver salts (black spots).

Comments: none
