Neuronal and non-neuronal scaling across brain regions within an intercross of domestic and wild chickens

open access: yesFrontiers in Neuroanatomy, 2022
The allometric scaling of the brain size and neuron number across species has been extensively studied in recent years. With the exception of primates, parrots, and songbirds, larger brains have more neurons but relatively lower neuronal densities than ...

Relative Brain Size and Cognitive Equivalence in Fishes

open access: yes, 2022
Scientists have long struggled to establish how larger brains translate into higher cognitive performance across species. While absolute brain size often yields high predictive power of performance, its positive correlation with body size warrants some ...

Causation, not collinearity: Identifying sources of bias when modelling the evolution of brain size and other allometric traits

open access: yesEvolution Letters, 2022
Many biological traits covary with body size, resulting in an allometric relationship. Identifying the evolutionary drivers of these traits is complicated by possible relationships between a candidate selective agent and body size itself, motivating the ...

Experience drives the development of movement-cognition correlations in a butterfly

open access: yesFrontiers in Ecology and Evolution, 2015
Correlations between behavioral traits are widespread, but the developmental genetic architecture of such correlations is poorly characterized. Understanding the developmental mechanisms that lead to correlations between behaviors has implications for ...

Sexually size dimorphic brains and song complexity in passerine birds [PDF]

open access: yes, 2004
Neural correlates of bird song involve the volume of particular song nuclei in the brain that govern song development, production, and perception. Intra- and interspecific variation in the volume of these song nuclei are associated with overall brain ...

Multivariate Meta-Analysis of Brain-Mass Correlations in Eutherian Mammals

open access: yesFrontiers in Neuroanatomy, 2016
The general assumption that brain size differences are an adequate proxy for subtler differences in brain organization turned neurobiologists towards the question why some groups of mammals such as primates, elephants, and whales have such remarkably ...

Music and the brain: disorders of musical listening [PDF]

open access: yes, 2006
The study of the brain bases for normal musical listening has advanced greatly in the last 30 years. The evidence from basic and clinical neuroscience suggests that listening to music involves many cognitive components with distinct brain substrates ...

Football and Dementia: Understanding the Link

open access: yesFrontiers in Psychiatry, 2022
Football, also known as soccer or association football, is popular but has a potential link with dementia developing in retired players. The FA and soccer regulators in the USA have imposed guidelines limiting players exposure to heading, despite ...

Relationship between brain size and digestive tract length support the expensive-tissue hypothesis in Feirana quadranus

open access: yesFrontiers in Ecology and Evolution, 2022
The brain is among the most energetically costly organs in the vertebrate body, while the size of the brain varies within species. The expensive-tissue hypothesis (ETH) predicts that increasing the size of another costly organ, such as the gut, should ...
