Developing pigeon retina: Light‐evoked responses and ultrastructure of outer segments and synapses
TLDR
Results are consistent with anatomical analysis of pigeon photoreceptor and synapse development, and indeed, photosensitive lamellae in the outer segments can be observed simultaneously with the appearance of the first retinal responses to light.
The Central and Peripheral Nervous System of Acoela (Plathelminthes). An Electron Microscopical Study
TLDR
The fine structure of the nerve cells and the neuropile in the brain of acoels and the peripheral nervous system and the synapses have been studied and the nervous system of acOels should no longer be considered as primitive.
The ultrastructure of the eyes in larval and adult polyclads (Turbellaria)
Examination of the larvae of Thysanozoon brocchii and Stylochus mediterraneus shows that they have both epidermal and cerebral eyes, while the young worms of Notoplana alcinoi have only cerebral
Olfactory nerve reconstitution in the homing pigeon after resection: ultrastructural and electrophysiological data.
TLDR
Total measurement of the cross surface of both olfactory nerves showed that the regenerated nerve is always smaller than the intact nerve; this is also apparent in the total number of the fibres counted.
Electron microscopic study of larval eye development in Turbellaria Polycladida
TLDR
The appearance and development of the embryonic and larval eyes of the polyclad turbellarian Stylochus mediterraneus were studied and a third eye is believed to originate through a process of induction.
Ultrastructural aspects of nervous-system and statocyst morphogenesis during embryonic development of Convoluta psammophila (Turbellaria, Acoela)
TLDR
Observations of serial TEM sections of embryos at different stages of development support the hypothesis of an inner (non-epithelial) origin of the statocyst.
The Symbiont Alga of the Flatworm Convoluta Psammophila Bekl. Observed at the Electron Microscope
TLDR
Convoluta psammophila is an acoel turbellarian found for the first time on the Black Sea coasts, and only recently at Marina di Pisa, and appears very similar to the symbiont of C. roscoffensis, generally considered as a species of the genus Carteria.
Electron microscopic study of larval eye development in Turbellaria Polycladida
TLDR
The appearance and development of the embryonic and larval eyes of the polyclad turbellarian Stylochus mediterraneus were studied and it is believed that a third eye is believed to originate through a process of induction.
THE FINE STRUCTURE OF THE PSEUDOCULUS OF ACERENTOMIDS PROTURA (INSECTA APTERYGOTA)
TLDR
The characteristic fine structure of the pseudoculus excludes its being an eye or a rudimentary antenna while the presence of ciliary processes and pore-canals lead to the conclusion that it is a sense organ with a chemosensory function.
