The evolution of mammalian brain size [PDF]

Science Advances, 2021
Relative brain size has long been considered a reflection of cognitive capacities and has played a fundamental role in developing core theories in the life sciences.

Evolutionary change in the brain size of bats [PDF]

Brain, Behavior and Evolution, 2012
It has been widely recognized that mammal brain size predominantly increases over evolutionary time. Safi et al. [Biol Lett 2005;1:283-286] questioned the generality of this trend, arguing that brain size evolution among bats involved reduction in ...

Covariation between brain size and immunity in birds: implications for brain size evolution [PDF]

Journal of Evolutionary Biology, 2005
Parasitism can negatively affect learning and cognition, setting the scene for coevolution between brain and immunity. Greater susceptibility to parasitism by males may impair their cognitive ability, and relatively greater male investment in immunity ...

Brain Connectivity and Brain Size

, 2009
The mammalian brain varies in volume by five orders of magnitude. These size differences also affect the connectivity of the brain. In this article, we compare the cerebral and the cerebellar cortex in small and large brains. Both cortices show an almost

Beyond brain size [PDF]

, 2017
Despite prolonged interest in comparing brain size and behavioral proxies of ‘intelligence’ across taxa, the adaptive and cognitive significance of brain size variation remains elusive.

Comparing brain asymmetries independently of brain size [PDF]

NeuroImage, 2021
Abstract Studies examining cerebral asymmetries typically divide the L-R Measure (e.g., Left– Right Volume) by the L+R Measure to obtain an Asymmetry Index (AI). However, contrary to widespread belief, such a division fails to render the AI independent from the L+R Measure and/or from total brain size.

Rethinking Phylogeny and Ontogeny in Hominin Brain Evolution [PDF]

, 2012
Theories of hominin and human cognitive evolution have traditionally focused on the phylogeny of the human brain, and on comparisons of human and primate brains in relation to social or ecological variables.

Brain size, body size and longevity [PDF]

International Journal of Obesity, 2010
In this analysis, we bring together two research fields that have never been associated before: the clinical issue 'Quételet's body-mass index and longevity' and the comparative biological issue 'body-brain allometry'. Comparison of medical and biological data supports the view that body mass index is just a one-to-one mapping of the body-brain-energy ...

Scaling of brain compartments to brain size [PDF]

NeuroReport, 2019
In this study, we examine the relationship between total brain volume (BV) and the volumes of several main brain compartmental (BC) measures (cortical thickness, cortical surface area, corpus callosum, cortical gray matter, normal appearing cerebral white matter (NAWM), amygdala, accumbens, caudate, hippocampus, putamen, pallidum, thalamus, cerebellar ...

Brain size, sex, and the aging brain [PDF]

Human Brain Mapping, 2014
This study was conducted to examine the statistical influence of brain size on cortical, subcortical, and cerebellar compartmental volumes. This brain size influence was especially studied to delineate interactions with Sex and Age. Here, we studied 856 healthy subjects of which 533 are classified as young and 323 as old.
