Distribution of GFAP in Squamata: Extended Immunonegative Areas, Astrocytes, High Diversity, and Their Bearing on Evolution

open access: yesFrontiers in Neuroanatomy, 2020
Squamata is one of the richest and most diverse extant groups. The present study investigates the glial fibrillary acidic protein (GFAP)-immunopositive elements of five lizard and three snake species; each represents a different family.

Gene expression mapping of the neuroectoderm across phyla – conservation and divergence of early brain anlagen between insects and vertebrates

open access: yeseLife, 2023
Gene expression has been employed for homologizing body regions across bilateria. The molecular comparison of vertebrate and fly brains has led to a number of disputed homology hypotheses.

Nest Relocation and Colony Founding in the Australian Desert Ant, Melophorus bagoti Lubbock (Hymenoptera: Formicidae)

open access: yesPsyche: A Journal of Entomology, 2010
Even after years of research on navigation in the Red Honey Ant, Melophorus bagoti, much of its life history remains elusive. Here, we present observations on nest relocation and the reproductive and founding stages of colonies.

The secondary loss of gyrencephaly as an example of evolutionary phenotypical reversal

open access: yesFrontiers in Neuroanatomy, 2013
Gyrencephaly (the folding of the surface of the neocortex) is a mammalian-specific trait present in almost all mammalian orders. Despite the widespread appearance of the trait, little is known about the mechanism of its genesis or its adaptive ...

Human brain evolution [PDF]

open access: yesCurrent Opinion in Behavioral Sciences, 2017
Abstract Although we share evolutionary history with other primates, examples of apparent cognitive and behavioral discontinuity between humans and other species abound. Neuroanatomical and molecular differences that distinguish the human brain are evident at several levels of organization.

Brain Asymmetry in Evolution [PDF]

open access: yes, 2021
In higher mammals, including primates and carnivores, the asymmetrical aspects of brain morphology and function have been shown to be species-related, sex-related, and subject to individual diversity, and are associated with cognition, emotion, language,

Neural Correlates of Vocal Repertoire in Primates

open access: yesFrontiers in Neuroscience, 2018
Understanding the nature of the relationship between vocal complexity and brain architecture across non-human primates may help elucidate some of the key elements underlying the evolution of human speech.

Novel neuroanatomical integration and scaling define avian brain shape evolution and development

open access: yeseLife, 2021
How do large and unique brains evolve? Historically, comparative neuroanatomical studies have attributed the evolutionary genesis of highly encephalized brains to deviations along, as well as from, conserved scaling relationships among brain regions ...

The Cytoarchitecture of the Tectal-Related Pallium of Squirrelfish, Holocentrus sp.

open access: yesFrontiers in Neuroanatomy, 2022
The squirrelfish, which live in visually complex coral reefs, have very large eyes and a special dual-system “day and night vision” retina. They also have atypical expansions of brain areas involved in processing visual information.

Evolution of brain elaboration [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2015
Large, complex brains have evolved independently in several lineages of protostomes and deuterostomes. Sensory centres in the brain increase in size and complexity in proportion to the importance of a particular sensory modality, yet often share circuit architecture because of constraints in processing sensory inputs.
