Grossberg's paleontology
Grossberg's cellular biology and paleontology
Table of Contents
Introduction
While the focus of Grossberg's concepts is on brain [neuron, module, modal architecture]s, his work does raise questions about much more general [cell, module, modal architecture]s and their [physiology, evolution]. From his own references to this, to my questions regarding a particular role during the Cambrian Period in paleontology, ?????
Co-evolution of membrane equations and on-center-off-surround anatomies?
- "Did the membrane equations and on-center-off-surround anatomies co-evolve during the evolutionary process, so that cell networks could process distributed feature patterns without noise saturation from the earliest stages of cellular organisms?" [Grossberg 2021 p75c2h0.55]
- CogEM type circuits are an ancient design! 490
- Homologous sensory and drive representations: Evolutionary precursors?
- An ancient design: Avalanche circuits for sequence learning 495
- What is the smallest network that can learn an arbitrary act? 495
"... What is the simplest network that can learn a complex sequence of actions. such as piano sonato, dance, or other skilled sequence of actions? What is the minimal number of cells needed to do this?
The answer is ONE! ..." [Grossberg 2021

Cambrian Period explosion of [complex, diverse] multicellular life
The richest explosion of evolutionary diversity occurred during the Cambrian Period, approximately ?570? million years (My) ago (Phanerozoic Eon -> Paleozoic Era -> Cabrian Period). During this period, ?number? phyla, ?number? orders of life emerged. This is well illustrated at the Tyrell Museum of Paleantology in Drumheller, Alberta Canada (I am a member), for example.
John Mattick's group at the University of Queensland in Australia ?suggested that this may have been the result of a much more sophisticated [organization, modularization] of genetic information that allowed for far more [compact, ?re-usable?, robust] coding segments, thereby permitting complex life forms.
Furthermore, have there been other key developments of higher-??? that are also manifested in [cell organelle, organ] evolution, in particular with the brain, for example the neocortex to cortex?
Brain tissue does not preserve in the rocks, but work has been done, especially via non-[invasive, destructive] measurements (eg X-ray) on cranial cavities of dinosairs.
