Evolution of the brain and intelligence
Trends in Cognitive Sciences, 2005Intelligence has evolved many times independently among vertebrates. Primates, elephants and cetaceans are assumed to be more intelligent than 'lower' mammals, the great apes and humans more than monkeys, and humans more than the great apes. Brain properties assumed to be relevant for intelligence are the (absolute or relative) size of the brain ...

Applied Mathematics and Computation, 1999
The author investigates the evolution of the brain by using the theory of Gaussian Adaptation (GA), that is the entropy of a population of signal patterns is maximized keeping the mean fitness of the population \(P\) at some suitable level. In the end, the author concluded that the GA - algorithm is a good second order approximation of the Darwinian ...

2006
Publisher Summary Studies of human brain function and dysfunction have provided data, including the identification of many genes essential for the normal human condition. Molecular evolution studies have provided evidence that the changes in some of these genes gave a selective advantage, and are thus primary candidates in the search for genes ...

Evolution of brain and language
Language Learning, 2009The evolution of language and the evolution of the brain are tightly interlinked. Language evolution represents a special kind of adaptation, in part because language is a complex behavior (as opposed to a physical feature) but also because changes are adaptive only to the extent that they increase either one's understanding of others, or one's ...

The Minicolumn and Evolution of the Brain
Brain, Behavior and Evolution, 2002The minicolumn is generally considered an elementary unit of the neocortex in all mammalian brains. This essential building block has been affected by changes in the circuitry of the cortex during evolution. Researchers believe that enlargement of the cortical surface occurs through the addition of minicolumns rather than of single neurons.

Epigenetics and brain evolution
Epigenomics, 2011Fundamental aspects of mammalian brain evolution occurred in the context of viviparity and placentation brought about by the epigenetic regulation of imprinted genes. Since the fetal placenta hormonally primes the maternal brain, two genomes in one individual are transgenerationally co-adapted to ensure maternal care and nurturing.

Brain, Behaviour and Evolution
Brain, Behavior and Evolution, 2008Relying heavily on Ramon-Moltner''s (1968) catalogue of central mammalian neurones according to their dendroarchitecture, supported by comparative anatomical and physiological evidence concerning connections and functions, a theory of the phylogenetic progression of central sensory systems is put forward.

Evolution and Disease of the Brain
Perspectives in Biology and Medicine, 1958become fossilized, but some evidence can be obtained by making casts of the interior of the cranium. In this way it has been possible for T. Edinger (i) to follow the evolution of the brain of the horse. Most of the reconstruction, however, has been inferred from laborious study of the brains of surviving animals believed, for sufficient reasons, to be

Evolution, brain, and the nature of language
Trends in Cognitive Sciences, 2013Language serves as a cornerstone for human cognition, yet much about its evolution remains puzzling. Recent research on this question parallels Darwin's attempt to explain both the unity of all species and their diversity. What has emerged from this research is that the unified nature of human language arises from a shared, species-specific ...

Brain Evolution and Archaeopteryx
Nature, 1968THE brain of Archaeopteryx lithographica, the earliest fossil bird, is known from a natural endocranial cast exposed in the famous specimen on display at the British Museum (Natural History). Edinger1 and de Beer2 have agreed that its brain was “similar in type and structure to that of reptiles and different from that of all other known birds” (ref. 2,
