Journal ArticleDOI
Cellular Scaling Rules for the Brains of Marsupials: Not as “Primitive” as Expected
Sandra E. Dos Santos,Jairo Porfirio,Felipe Barros da Cunha,Paul R. Manger,William Corrêa Tavares,Leila Maria Pessôa,Mary Ann Raghanti,Chet C. Sherwood,Suzana Herculano-Houzel +8 more
TL;DR: The results suggest that Australasian marsupials have diverged from the ancestral Theria neuronal scaling rules, and support the suggestion that the scaling of average neuronal cell size with increasing numbers of neurons varies in evolution independently of the allocation of neurons across structures.
Journal ArticleDOI
The discovery of central monoamine neurons gave volume transmission to the wired brain.
Kjell Fuxe,Annica Dahlström,Gösta Jonsson,Daniel Marcellino,Michele Guescini,Mauro Dam,Paul R. Manger,Luigi F. Agnati +7 more
TL;DR: The differential properties of the wiring transmission (WT) and VT circuits and communication channels will be discussed as well as the role of neurosteroids and oxytocin receptors in volume transmission leading to a new understanding of the integrative actions of neuronal-glial networks.
Journal ArticleDOI
Natural sleep and its seasonal variations in three pre-industrial societies.
Gandhi Yetish,Hillard Kaplan,Michael Gurven,Brian M. Wood,Herman Pontzer,Paul R. Manger,Charles L. Wilson,Ronald McGregor,Jerome M. Siegel +8 more
TL;DR: The sleep period consistently occurred during the nighttime period of falling environmental temperature, was not interrupted by extended periods of waking, and terminated, with vasoconstriction, near the nadir of daily ambient temperature.
Journal ArticleDOI
Cetacean sleep: an unusual form of mammalian sleep.
TL;DR: The suggestion is made that the selection pressure necessitating the evolution of cetacean sleep was most likely the need to offset heat loss to the water from birth and throughout life.
Journal ArticleDOI
An examination of cetacean brain structure with a novel hypothesis correlating thermogenesis to the evolution of a big brain
TL;DR: It is shown that a combination of an unusually high number of glial cells and unihemispheric sleep phenomenology make the cetacean brain an efficient thermogenetic organ, which is needed to counteract heat loss to the water.
