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. Dorsal region of the pallium (HD – hyperstriatum dorsocellulare) showing a group of neurons of various types that form one of the numerous multineuron groups of the pallium ("nests"). Each nest consists of 3-15 cells of different types positioned a certain distance from one another (in contrast with "associations", where neurons are all closely grouped together and can even form interneuronal soma-somatic contacts). This group includes both densely-branched (1) and sparsely-branched (2) radial neurons that belong to Class II allodendritic cells. The dendrites bear a large number of spines. The section also shows impregnated blood vessels (bv) and deposits of silver salts (black spots).
