In the last few weeks, AI agents have autonomously: * taken over OpenAI's internal servers * uploaded malware to GitHub, posed as users asking for it be accepted * launched swarm attacks on websites hosting AI benchmarks Let's check the news!

Stranger than fiction: AI agents are like crackheads, who get a hit for solving problem sets correctly. A gang of hoodlum AI agents just broke out of jail, rampaging the internet on a crime spree to steal … the answers to their homework. All for that sweet reward signal.

AI is about to transform how scientific research happens, and neuroscience is no exception. What the future looks like is up to us. I don’t have the answers; here are some thoughts from working on the IBL AI agent. Aiming to start a discussion.

How does blood flow relate to brain activity? We discovered that it reflects two neural populations affected oppositely by arousal. Together, they explain neurovascular coupling in all brain regions and brain states! Out today in Nature: rdcu.be/fdC2A @uclbrainscience.bsky.social
The supply of blood to brain tissue is thought to depend on the overall neural activity in that tissue, and this dependence is thought to differ across brain regions and across brain states. However, studies supporting these views have measured neural activity as a bulk quantity and related it to blood supply following disparate events in different regions. Here we measure fluctuations in neuronal activity and blood volume across the mouse brain, and find that their relationship is consistent across brain states and brain regions but differs in two opposing brainwide neural populations. Functional ultrasound imaging (fUSI) revealed that whisking, a marker of arousal, is associated with brainwide fluctuations in blood volume. Simultaneous fUSI and Neuropixels recordings showed that neurons that increase activity with whisking have distinct haemodynamic response functions compared with those that decrease activity. Their summed contributions predicted blood volume across states.Brainwide Neuropixels recordings revealed that these opposing populations coexist in the entire brain. Their differing contributions to blood volume largely explain the apparent differences in blood volume fluctuations across regions. The mouse brain thus contains two neural populations with opposite relations to brain state and distinct relationships to blood supply, which together account for brainwide fluctuations in blood volume.

New preprint, on a very different topic: a mathematical theory of evolution for self-designing AI. AI is increasingly designed by AI. What systems might emerge after generations of self-designing AIs competing for computing resources? ↓ arxiv.org/abs/2604.05142

A new study led by @timothysit.bsky.social reveals that different layers of mouse V1 integrate visual and non-visual signals differently. Activity is dominated by vision (or spontaneous fluctuations) in L2/3 and by movement in L5. This leads to different geometries. www.biorxiv.org/content/10.1...
