TL;DR: Distributions of diameters were similar in the three systems of cortico-cortical fibres investigated, both in humans and the monkey, with most of the average values below 1 $$\upmu $$μm diameter and a small population of much thicker fibres.

TL;DR: The balance of evidence suggests that dopaminergic neurones are involved in the light/dark adaptation process in the mammalian retina, and are likely to become model modes of neurochemical action in the nervous system.

TL;DR: Three different aspects of the morphological organisation of deep-sea fish retinae are reviewed: questions of general cell biological relevance are addressed with respect to the development and proliferation patterns of photoreceptors, and problems associated with the growth of multibank retinae, and with outer segment renewal are discussed.

TL;DR: Patients with a tumor burden >75% of the liver did not benefit from TACE due to the development of major complications, whereas patients with low tumor burden and high lipiodol uptake showed a trend towards longer survival.

TL;DR: Current research on different communication systems (visual, chemical, acoustic, electric) and the state of knowledge of how complex systems respond to environmental stressors using fish as a model are discussed and an urgent need for a better understanding of the evolutionary consequences of changes in communication systems on fish diversity is seen.
