The Limbic System in Mammalian Brain Evolution

The limbic system in Mammalian brain evolution.

Previous accounts of mammalian brain allometry have relied largely on data from primates, insectivores and bats. Here we examine scaling of brain structures in carnivores, ungulates, xenarthrans and sirenians, taxa chosen to maximize potential olfactory and limbic system variability. The data were compared to known scaling of the same structures in bats, insectivores and primates. Fundamental p...

The limbic system and the “religious brain”

The human body is a fascinating and complex array and composition of protoplasm that is arranged in cells, organs and other substructures. The body has one common goal: to survive. To ensure survival, the body has to be kept intact and protected from the outside world by the largest organ – the skin. Under the skin, a most fascinating array of cells and substructures are systematically and func...

On the Evolution of the Mammalian Brain

Hobson and Friston have hypothesized that the brain must actively dissipate heat in order to process information (Hobson et al., 2014). This physiologic trait is functionally homologous with the first instantation of life formed by lipids suspended in water forming micelles- allowing the reduction in entropy (heat dissipation). This circumvents the Second Law of Thermodynamics permitting the tr...

The Limbic System Conception and Its Historical Evolution

Throughout the centuries, scientific observers have endeavoured to extend their knowledge of the interrelationships between the brain and its regulatory control of human emotions and behaviour. Since the time of physicians such as Aristotle and Galen and the more recent observations of clinicians and neuropathologists such as Broca, Papez, and McLean, the field of affective neuroscience has mat...
