In the end of the day, these companies probably realized that, just like with AI, they can somehow use scare tactics to attract venture capital.

The headline of the Science article reads: Not alive, but not dead: disembodied human brains used for drug testing By restoring some functions to intact brains from deceased donors, the startup Bexorg hopes to create a better drug development test bed for neurodegenerative diseases, written by Sara Reardon, published on the 20th of May 2026. Though, reading this Science article made me think: aren't we the brain? Am I missing something here? Now, of course the devil lies in the detail and the article makes it clear that this startup only restores “some functions”, which is certainly more complex in action than it is in theory written here, but certain language of the article makes me question the author's understanding of what is a human. The article writes: “Just a day ago, the brain was in a living person. Now, hours after its owner died, it sits on a cart draped in tubes [...]” What do you mean “it's owner” — isn't the brain it's owner? Isn't that where it's owner is? I mean, certainly the brain had no more activity, the person must've been declared brain dead by all standards before being sent to this startup, still it's odd hearing someone donated their brain instead of saying they've donated... themselves? Also “using a set of proprietary brain-sustaining machines” is a terrible sentence I always thought the people who don't donate their full body to hospitals are religious lunatics, but this is the first time I wrote something on my organ donor card. They can take my brain, but not as one piece."

Playing Terra Nil right now, and it's funny because from the promo stuff I thought I wouldn't like it much, yet I'm enjoying myself a lot. There's definitely a game design lesson to be leaned here.
I was absolutely correct in my assessment that the game feels like it's actively trying to make suspension of disbelief as hard as possible with its completely ridiculous mechanics that make absolutely zero sense. "That's... Not how that works at all!" Is basically playing on repeat in my brain.
Furthermore, the entire technosolutionist tenor of the game rubs me very much the wrong way. This compounds with the physics- and biology-defying (or perhaps -spiting) fictional layer in cases like the convenient magical radiation-absorbing buildings so that you can reverse radiation contamination with a few simple clicks to be extremely bad politics actually...
But... The mechanics do work together quite well to make interesting puzzles with good gameplay that includes satisfying variety and challenges. The art is wonderful, and the music and audio design are spot on. The the result of each level is immensely satisfying, and the pacing is excellent.
I guess the lesson I'm taking away from this is that really solid fundamentals can triumph over an absolute cacophony of ludonarrative dissonance. That doesn't mean that in every decision between ludonarrative harmony (or just straight up believability) and neat mechanics you should compromise towards mechanics, but it reinforces the idea that if you make the mechanics enjoyable in the abstract, players (or at least, players like me) will be willing to compromise a *lot* on whether it actually makes any sense for things to work that way.
I'm still bothered by the "use technology to fix everything" politics, which prevents this game from being one I'll enthusiastically recommend, but despite myself I am having a lot of fun with it.

MORSE-PI -- Flexible and artefact-free image reconstruction for structural and functional QSM and other phase-critical imaging applications
Barbara Dymerska, Oliver Josephs, Benjamin James, Vahid Malekian, Nadine N. Graedel, Martina F. Callaghan
https://arxiv.org/abs/2606.21336 https://arxiv.org/pdf/2606.21336 https://arxiv.org/html/2606.21336
arXiv:2606.21336v1 Announce Type: new
Abstract: Phase imaging applications such as QSM are highly sensitive to noise amplifications, phase singularities, and other artefacts, particularly in challenging scenarios such as ultra-high field (7T), under-sampled or single-echo acquisitions. We present a novel image reconstruction method, MORSE-PI, designed to produce high-SNR, artefact-free, and singularity-free phase images for both structural and functional phase-based brain imaging. MORSE-PI extends our previous approach, MORSE, by introducing a Virtual Reference Coil (VRC). The VRC is constructed as a linear combination of coil sensitivity maps, with correlations enhanced between coil elements using the noise covariance matrix. Such a VRC ensures robust signal support across the entire brain and is used to correct phase offsets in the MORSE-derived coil sensitivity estimates, resulting in artefact-free, high SNR phase. Compared to GRAPPA with ASPIRE phase correction, MORSE-PI demonstrates greater robustness to artefacts such as noise amplification and aliasing, and shows improved reproducibility in structural imaging at both 3T and 7T. Unlike ESPIRiT and GRAPPA combined with adaptive coil combination methods, MORSE-PI yields singularity-free phase maps. MORSE-PI enables high-SNR reconstructions even for the most challenging scenarios, such as single-echo EPI at 7T. Its efficient, containerised implementation using the Gadgetron framework supports deployment on the MRI scanner console during measurements. MORSE-PI offers a flexible and computationally efficient solution for generating high-SNR, artefact- and singularity-free phase images in both single- and multi-echo GRE and EPI acquisitions. This makes it particularly well-suited for structural and functional QSM, as well as other phase-based MRI applications. Its robustness and rapid computational time facilitate efficient deployment on scanners across field strengths.

Government Strategy Is Shaping the Global Brain-Computer Interface Race   - Neurotech Reports
Three events converged this year to turn brain-computer interfaces from a research curiosity into a subject of government strategy. China moved a product to market, having already built the machinery to pay for it. The U.S. funded a founder. The European Union asked its regulators to study a problem. This is not an accident of timing. It reflects fundamentally different beliefs about what a government should do when a new technology can read, and may soon write to, the human brain.

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.

Abstract: Objective: Present OpenPINT (Open-source Planning for Isoeffective Nuclear Treatments), an open-source treatment planning system for nuclear therapies that integrates Monte Carlo dose calculations with modular dosimetric and radiobiological models for photon-isoeffective dose evaluation.
Approach: We describe the software architecture, implementation choices, and data flow from segmented geometry and source configuration to NIfTI dose outputs. We define BNCT-relevant dosimetric metrics and evaluate the workflow with reproducible analytic and voxelized cylindrical-phantom benchmarks, supplemented by a geometric patient-positioning example.
Main results: The module provides a reproducible and scriptable path for generating MCNP-ready inputs, extracting component-wise BNCT dose maps, and computing analysis-ready outputs for quality checks and decision support. Fine-resolution voxelized configurations reproduced the 1 mm analytic reference within 0.13% for the brain-limited irradiation-time endpoint, whereas the full voxelized sweep exposed deviations up to 4.42% in coarse 8--10 mm configurations. Patient-wide gamma pass rates were at least 99.60% for the evaluated mesh/interpolation cases, while low-dose DVH-tail quantities remained sensitive to boundary discretization.
Significance: This first paper isolates and validates the simulation-preparation and dosimetric-analysis core of an open-source BNCT treatment-planning platform. It establishes a foundation for subsequent work on optimization, biological weighting, and clinical workflow integration.

Abstract: Slice-to-volume reconstruction (SVR) is the standard method for obtaining high-resolution (HR) 3D fetal brain volumes from motion-corrupted 2D MRI slice stacks acquired in multiple orientations. Existing SVR methods are optimized and validated only for clinical-range echo times (TEs), limiting their use at non-clinical TEs and making them incompatible with quantitative T2 mapping, a protocol- and center-independent biomarker of fetal brain maturation requiring HR reconstructions across multiple TEs. We present PRIME-SVR, the first implicit neural representation (INR) framework for joint HR reconstruction from multi-echo MRI. A single fully connected network models a continuous function from spatial coordinates to signal intensities across TEs, while a second network estimates slice-specific acquisition degradations. Cross-TE coherence is enforced via a Bloch equation-derived regularization penalizing deviations from expected T2 decay, with adaptive weighting that strengthens coupling for degraded stacks. The method is fully self-supervised. We validate PRIME-SVR on 39 in vivo fetal acquisitions (13 subjects x 3 TEs) from two centers, two vendors, and two field strengths (1.5 T and 0.55 T). Compared to state-of-the-art SVR, PRIME-SVR improves reconstruction sharpness by 47%, anatomical accuracy by 30%, and cross-TE structural consistency by 14%. It enables reconstruction at late TEs previously inaccessible to SVR, yielding the first 0.8 mm isotropic T2 maps at 0.55 T and the first T2 maps derived from INR-based SVR. PRIME-SVR also accelerates quantitative imaging by reducing the data needed for multi-TE reconstruction, cutting acquisition from 15 to 10 minutes while keeping T2 accuracy within 1.7% in white and deep gray matter, or to 5 minutes with a mean T2 error of 2.3% for high-quality acquisitions.

Non-invasive mapping of the temporal processing hierarchy in the human visual cortex
Author summary Vision doesn’t happen instantaneously, but unfolds over time. While we understand a lot about how the brain processes visual space, understanding how the brain processes information over both space and time is much more challenging. Vision happens incredibly fast, space and time are tightly linked, but current technology is limited in capturing these spatiotemporal dynamics. Here, we developed a method that combines two non-invasive human brain imaging techniques using computat…

Intermittent fasting triggers surprising changes in the brain #health

Intermittent fasting triggers surprising changes in the brain
Losing weight may involve rewiring the gut and the brain at the same time. In a study of obese adults, an intermittent fasting-style diet led to significant weight loss, healthier metabolic markers, and notable shifts in gut bacteria. Brain scans also revealed changes in regions tied to appetite, cravings, and self-control. The results suggest the gut microbiome and brain may work together to influence weight-loss success.

Neuroscientists long theorized that bilingual speakers must process different languages with separate patterns of brain activity.
In a new study, however, researchers found that these patterns were more alike than had been expected.
When deciding how to make a word singular or plural, for instance,
bilingual people exhibit strikingly similar brain activity regardless of whether they are speaking in their first or second language.

Scientists discover a surprising link between vitamin C and brain health
Could something as simple as vitamin C help support a healthier aging brain? In a study of more than 2,000 older adults in Japan, researchers found that people with lower vitamin C levels in their blood also tended to have less gray matter and weaker connections in a key brain network involved in memory, attention, and other cognitive functions.

Mysterious waves sweeping across your brain may help turn sensory chaos into what you see
Traveling electrical waves sweeping across the brain may help determine what we notice, predict what comes next, and construct our internal picture of the world. Researchers now argue that these waves aren't just background activity—they could be a core computational engine behind perception and memory.

Long-term stability of cellular-resolution brain-computer interface recordings after stroke #BCI

Long-term stability of cellular-resolution brain-computer interface recordings after stroke
Implantable brain-computer interfaces (iBCIs) with single-neuron resolution are showing great promise for restoring mobility and communication in individuals with spinal cord injury or motor neuron disease. Stroke is the most common cause of acquired brain injury and a major contributor to long-term disability, making chronic stroke a highly relevant indication for iBCIs. However, whether stable intracortical recordings can be obtained from the structurally lesioned human brain is unknown. We r…

A visual imagery paradigm for BCI strategies using imagined flickering patterns - Scientific Reports
Steady state visually evoked potentials (SSVEPs) are a popular type of control signals in brain-computer interfaces (BCIs), in which they are typically elicited by observing a visual stimulus flashing at a specific frequency. For some patients, using SSVEP as control signal for a BCI can be difficult, for instance if they are unable to focus their gaze over the visual stimuli. To address this issue, some approaches were presented to design a gaze-independent SSVEP-controlled BCI but some diffic…

Version v3 of the white paper and living document on The vOICe vision BCI and brain implants for restoring vision is now on Zenodo #BCI

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

Discovering Functionally Selective Brain Regions with a Deep Topographic Multimodal Model
Nearby neurons in cortex share similar response profiles, producing systematic spatial organization across sensory and cognitive systems. Recent topographic models reproduce aspects of this structure but remain unimodal and spatially constrain each layer separately, yielding fragmented maps that capture neither the contiguity of cortical processing streams nor their integration across modalities. We introduce Topo-Omni, a topographic multimodal model in which visual, auditory, and language/cogn…
