Current perspectives on brain evolution relate brain size variability to two main parameters:
a scaling factor that corresponds to overall body size and an ecological factor associated …

The role of brain size as a cost of learning remains enigmatic; the nature and timing of such
costs is particularly uncertain. On one hand, comparative studies suggest that congenitally …

The size of the brain—its weight or volume—is an extraordinarily useful measure in
neurobiology. Other chapters in this volume show many of the ways in which it is useful. In …

Evolution has generated mammalian brains that vary by a factor of over 100,000 in mass.
Despite such tremendous diversity, brain scaling in mammalian evolution has tacitly been …

Development and Evolution of Brain Size: Behavioral Implications contains the proceedings
of a symposium entitled"" Development and Evolution of Brain Size: Behavioral …

The heritability of brain size is approximately. 6 at both 38 and 70 days of age, a value which
is almost identical with other studies on mice. Ontogenetic data indicates that the genetic …

Neurons are the basic computational units of the brain, but brain size is the predominant
surrogate measure of brain functional capacity in comparative and cognitive neuroscience …

Variation in relative brain size is commonly interpreted as the result of selection on neuronal
capacity. However, this approach ignores that relative brain size is also linked to another …

The current paper details our developing understanding of the evolution of large brains in
mammals. In order to do this, we first define brains that we consider to be large-those that …

Harry Jerison argued in his Evolution of the Brain and Intelligence that the initial
enlargement of the brain of ancestral mammals resulted from refinement of the sensory …
