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.

budapest_connectome: Budapest Reference Connectome 3.0
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.
This network has 1015 nodes and 121755 edges.

My local grocery store has an aisle labeled "conven. breakfast" where all the granola bars, poptarts, etc are sold. Presumably this is an abbreviation of "convenient".
My brain keeps trying to interpret that as an abbrevation of "convent" and I picture a bunch of nuns sitting around a table eating poptarts

Thy gift, thy tables, are within my brain

Beyond all date, even to eternity:
Or, at the least, so long as brain and heart
Have faculty by nature to subsist;
Till each to razed oblivion yield his part
Of thee, thy record never can be missed.
That poor retention could not so much hold,
Nor need I tallies thy dear love to score;

Exploring Brain Networks Using Noninvasive Electrophysiological Measurements: Methods and Applications
Richard Leahy, Takfarinas Medani
https://arxiv.org/abs/2607.17602 https://arxiv.org/pdf/2607.17602 https://arxiv.org/html/2607.17602

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.

An enzyme found in the brain could help to preserve cognitive resilience with advancing age, according to research in mice, humans and cells1.
Researchers found that high levels of the enzyme are linked to low levels of inflammation in the brains of aged mice.
They also showed that the enzyme boosts the growth of neurons in ageing brains. The findings were reported on 15 October in Nature Neuroscience.
The enzyme seems to act “as a compensatory cognitive-resilience mechanism…

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

The point here is what retirement means.

learning new and complex skills,
then that’s actually not retirement.

Every cell in your body has the potential to get smarter.
I don’t mean this metaphorically, or in a “body keeps the score” kind of way.
I mean that if lab-coated biologists took a sample of your skin and very carefully manipulated the cells inside it, they could actually make a brain.
They do it all the time.
Mini human brains are being grown in labs all over the world.
Soon, they could outthink neural networks.
