The distribution of crossed and uncrossed optic fibers in the different layers of the lateral geniculate nucleus in the tree shrew (Tupaia glis).
Hajdu F, Hassler R, Wagner A. Hajdu F, et al. Anat Embryol (Berl). 1982;164(1):1-8. doi: 10.1007/BF00301874. Anat Embryol (Berl). 1982. PMID: 7114482
By using formvar film-coated slot grids, all six layers of the LGN could be studied in a single ultrathin section. Degeneration of crossed optic fibers was observed in layers 1, 3, 4 and 5 of the contralateral LGN. ...

Degenerated boutons in the fundus striati (nucleus accumbens septi) after lesion of the parafascicular nucleus in the cat.
Chung JW, Hassler R, Wagner A. Chung JW, et al. Cell Tissue Res. 1976 Sep 6;172(1):1-14. doi: 10.1007/BF00226045. Cell Tissue Res. 1976. PMID: 991200
Two types of synaptic contacts were found to be degenerated two days after the lesion was performed: (1) the axo-spinous type IV, characterized by densely-packed, small, round vesicles and a strong asymmetric thickening, and (2) the axo-dendritic or axo-somatic type VII, a …

The different types of synapses in the thalamic nucleus ventralis anterior (VA) of Saimiri sciureus and their degeneration after pallidum coagulation.
Nitecka L, Hassler R, Bialowas J, Wagner A. Nitecka L, et al. J Hirnforsch. 1983;24(2):149-64. J Hirnforsch. 1983. PMID: 6886386
The type V SO (Small bouton, Ovoid vesicles) synapses, the most frequent type of synapses, have larger pale ovoid vesicles in a bell-shaped bouton that is in asymmetric contact with a small dendrite. The subtype V St, which likewise contains pale ovoid vesicles has …

After columnar isolation of the cat's fundus striati with a survival time of 2 days or 2 or 4 weeks all axospinous boutons (type I, III And iv) and most axo-dendritic (or axo-somatic) boutons (type II, VI and VII) undergo dark degeneration. All specimens of axo-somatic (or …

The lateral geniculate nucleus (LGN) of Aotus trivirgatus and Nycticebus coucang shows two types of neurons at the ultrastructural level: a large thalamo-cortical relay neuron (TCR) and a small neuron of Golgi type II, which is considered to be an interneuron. The i …

Whereas after 3 days dark bouton degeneration was rare, after 4- and 5-day survival it was regularly found for a distinct type of synapse containing in its bouton densely packed small round vesicles and possessing an asymmetric synaptic junction with a dendrite. Oft …
