The brain regulatory program predates central nervous system evolution [PDF]

Scientific Reports, 2023
Understanding how brains evolved is critical to determine the origin(s) of centralized nervous systems. Brains are patterned along their anteroposterior axis by stripes of gene expression that appear to be conserved, suggesting brains are homologous ...

Intron and gene size expansion during nervous system evolution [PDF]

BMC Genomics, 2020
Background The evolutionary radiation of animals was accompanied by extensive expansion of gene and genome sizes, increased isoform diversity, and complexity of regulation.

Voltage-gated ion channel diversity underlies neuronal excitability and nervous system evolution [PDF]

Nature Communications
Nervous systems function via electrical excitability mediated by ion channels, an ancient preneuronal feature that many cells use to rapidly adjust behavior.

Incorporating evolution into neuroscience teaching

Frontiers in Education, 2023
Neuroscience courses can be enriched by including an evolutionary perspective. To that end, this essay identifies several concepts critical to understanding nervous system evolution and offers numerous examples that can be used to illustrate those ...

Nitric oxide signaling in ctenophores

Frontiers in Neuroscience, 2023
Nitric oxide (NO) is one of the most ancient and versatile signal molecules across all domains of life. NO signaling might also play an essential role in the origin of animal organization.

Functional Conservation and Genetic Divergence of Chordate Glycinergic Neurotransmission: Insights from Amphioxus Glycine Transporters

Cells, 2021
Glycine is an important neurotransmitter in vertebrates, performing both excitatory and inhibitory actions. Synaptic levels of glycine are tightly controlled by the action of two glycine transporters, GlyT1 and GlyT2, located on the surface of glial ...

Alternative neural systems: What is a neuron? (Ctenophores, sponges and placozoans)

Frontiers in Cell and Developmental Biology, 2022
How to make a neuron, a synapse, and a neural circuit? Is there only one ‘design’ for a neural architecture with a universally shared genomic blueprint across species?

Modeling spontaneous activity across an excitable epitheliumSupport for a coordination scenario of early neural evolution

Frontiers in Computational Neuroscience, 2015
Internal coordination models hold that early nervous systems evolved in the first place to coordinate internal activity at a multicellular level, most notably the use of multicellular contractility as an effector for motility.
