Humans, fish, spiders and bees inherited working memory and attention from their last common ancestor

open access: yesFrontiers in Psychology, 2023
All brain processes that generate behaviour, apart from reflexes, operate with information that is in an “activated” state. This activated information, which is known as working memory (WM), is generated by the effect of attentional processes on incoming

Twelve protections evolved for the brain, and their roles in extending its functional life

open access: yesFrontiers in Neuroanatomy, 2023
As human longevity has increased, we have come to understand the ability of the brain to function into advanced age, but also its vulnerability with age, apparent in the age-related dementias.

Selection of Olduvai Domains during Evolution: A Role for Primate-Specific Splicing Super-Enhancer and RNA Guanine Quadruplex in Bipartite NBPF Exons

open access: yesBrain Sciences, 2022
Olduvai protein domains (also known as DUF1220 or NBPF) have undergone the greatest human-specific increase in the copy number of any coding region in the genome.

New Remains of Scandiavis mikkelseni Inform Avian Phylogenetic Relationships and Brain Evolution

open access: yesDiversity, 2021
Although an increasing number of studies are combining skeletal and neural morphology data in a phylogenetic context, most studies do not include extinct taxa due to the rarity of preserved endocasts.

A Closer Look to the Evolution of Neurons in Humans and Apes Using Stem-Cell-Derived Model Systems

open access: yesFrontiers in Cell and Developmental Biology, 2021
The cellular, molecular and functional comparison of neurons from closely related species is crucial in evolutionary neurobiology. The access to living tissue and post-mortem brains of humans and non-human primates is limited and the state of the tissue ...

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.

Evolution in the Social Brain

open access: yesScience, 2007
The evolution of unusually large brains in some groups of animals, notably primates, has long been a puzzle. Although early explanations tended to emphasize the brain's role in sensory or technical competence (foraging skills, innovations, and way-finding), the balance of evidence now clearly favors the suggestion that it was the computational demands ...
