claimKeijzer and Arnellos (2017) argue that nervous systems evolved to allow for the coordination of an organism’s body, a development that must have occurred long before the Cambrian Explosion.
claimNervous systems in the biological world show a gradual transition from playing a role in internal organization to taking on an outward-oriented role, where action emerges out of development.
claimThe role of muscles in the evolution of nervous systems has been underestimated, as nerve nets primarily evolved to control muscles in the service of adaptive behavior.
claimThe Cambrian explosion, occurring over a 20 million-year timespan, resulted in the development of complex multicellular body plans, nervous systems, behavioral repertoires, and sensing modes in several lineages that are considered likely candidates for subjective experience.
The Energy Homeostasis Principle: A Naturalistic Approach to ... frontiersin.org 3 facts
claimLarger nervous systems, characterized by a greater number of neurons, are associated with greater behavioral richness.
claimNervous systems grow and develop from the embryonal stage in continuous coupling, adaptation, and structural coherence with both their biological surroundings and the extra-organism environment.
referenceComplex nervous systems are hierarchically organized as second-order homeostatic systems, which allows them to exhibit ultrastability and flexibility, as described by W. Ross Ashby in 1960.
Thinking about the action potential: the nerve signal as a window to ... frontiersin.org 1 fact
claimAnimals with nervous systems translate diverse incoming physical and chemical signals from external sources (such as light rays and sound waves) and internal sources (such as local pH, pressure, temperature, and chemical mediators like hormones, neurotransmitters, or inflammatory stimulants) into electrical messages that travel along neurons.
(PDF) The Evolutionary Rationale for Consciousness - ResearchGate researchgate.net 1 fact
claimThe author of 'The Evolutionary Rationale for Consciousness' proposes that the evolutionary trajectory leading to the development of consciousness begins with the emergence of nervous systems.
Physiology, Homeostasis - StatPearls - NCBI Bookshelf ncbi.nlm.nih.gov May 1, 2023 1 fact
claimHomeostatic regulation occurs through local control, such as paracrine or autocrine responses, and reflex control, which involves the nervous and endocrine systems.

claimHuman brain organoids, which are in vitro models of brain development created via three-dimensional stem cell culture, have raised concerns regarding their potential moral status if they develop physiological features of organisms with nervous systems.
