New research shows that what we call the human brain is actually two ancient, independent nervous systems assembled side by side over hundreds of millions of years of evolutionary history.
“We’ve shown for the first time that the front of the brain arises from a totally different progenitor cell than the back of the brain,”
said Kyle Loh, Ph.D., associate professor of developmental biology at Stanford Medicine and senior author of the study.

Just went to look into what the “propagator model of computation” is, and read just enough to understand that it may be a better basis for actual AI than the LLM and diffusion models. Also just enough to recognize that I no longer have the brain of my 20’s, when I positively hoovered up such things.
Exploring Brain Networks Using Noninvasive Electrophysiological Measurements: Methods and Applications

Abstract: Electroencephalography (EEG) and magnetoencephalography (MEG) provide noninvasive measurements of brain activity with millisecond temporal resolution, enabling the investigation of functional and effective interactions within large-scale brain networks. This chapter presents a comprehensive overview of the methodological foundations and practical workflows for EEG/MEG-based brain network analysis. We first review the physical principles underlying EEG and MEG, emphasizing their complementary strengths and limitations. We then describe the forward and inverse problems, including subject-specific head modeling, source reconstruction techniques, and the importance of accurate anatomical modeling for reliable source localization. Strategies for mitigating volume conduction and signal leakage are discussed, together with best practices for source-space connectivity analysis. The chapter reviews widely used functional and effective connectivity measures, including coherence, phase synchronization metrics, amplitude envelope correlation, Granger causality, dynamic causal modeling, and transfer entropy, highlighting their assumptions, advantages, and limitations. Modern end-to-end analysis pipelines are presented, with particular emphasis on Brainstorm and complementary open-source software for reproducible EEG/MEG research. Finally, we discuss emerging approaches, including time-varying connectivity, cross-frequency interactions, and network-based analyses, illustrating how noninvasive electrophysiology contributes to understanding brain organization in health and disease. The chapter provides both conceptual foundations and practical guidance for researchers and advanced students seeking to map and interpret human brain networks using EEG and MEG.

A parameterizable consensus brain graph, derived from connectomes of 477 people, each computed from MRI datasets of the Human Connectome Project. Nodes are brain regions, and edges are weighted by the number of "tracks" that run between two nodes, as well as fiber length, fractional anisotropy and the number of occurrences in each of the 477 individuals.

To ChatGPT: Will a Phosphoenix LGN brain implant really become a product for restoring vision to the blind, or is this mostly an intermediate goal serving European BCI technology development? https://chatgpt.com/share/6aaf827f-c700-83ed-a8a9-c95bcf3deb94
For Elon Musk, Neuralink Blindsight likely merely temporarily serves his current PR needs ("Jesus-level" technology) and as a stepping stone to treating other conditions that are not for a niche market like blindness, or as a stepping stone to mass-market consumer BCIs with AI. Musk is unlikely to do anything mature and sustainable for blindness.
The vOICe vision BCI, on the other hand, has the singular goal of bringing a lasting equivalent of (low) vision to the world
