Evolution of cephalopod nervous systems [PDF]

open access: hybridCurrent Biology, 2023
Giant brains have independently evolved twice on this planet, in vertebrates and in cephalopods (Figure 1A). Thus, the brains and nervous systems of cephalopods provide an important counterpoint to vertebrates in the search for generalities of brain organization and function.

The evolution of nervous system centralization [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2008
It is yet unknown when and in what form the central nervous system in Bilateria first came into place and how it further evolved in the different bilaterian phyla. To find out, a series of recent molecular studies have compared neurodevelopment in slow-evolving deuterostome and protostome invertebrates, such as the enteropneust ...

The substrate of the biopsychosocial influences in the carcinogenesis of the digestive tract [PDF]

open access: yes, 2016
Digestive cancer represents a severe public health problem, being one of the main causes of death. It is considered a multifactorial disease, with hereditary predisposition, environmental factors, and other factors involved in carcinogenesis.

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

open access: yesCells, 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)

open access: yesFrontiers 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

open access: yesFrontiers 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.

Expanding of Life Strategies in Placozoa: Insights From Long-Term Culturing of Trichoplax and Hoilungia

open access: yesFrontiers in Cell and Developmental Biology, 2022
Placozoans are essential reference species for understanding the origins and evolution of animal organization. However, little is known about their life strategies in natural habitats.

Neuronal Control of Swimming Behavior: Comparison of Vertebrate and Invertebrate Model Systems [PDF]

open access: yes, 2011
Swimming movements in the leech and lamprey are highly analogous, and lack homology. Thus, similarities in mechanisms must arise from convergent evolution rather than from common ancestry.
