Most studies ask what #oxytocin does by giving it from the outside. But what happens when the brain releases its own? The answer: not a single "oxytocin circuit" but a profound reorganization of brain network dynamics (fMRI + ePhys) favoring salience-related states! 👉 tinyurl.com/mryc8rp6

A gigantic test, 650 infants across 30 laboratories, finds "no evidence" for Marcus et al.'s ABB rule learning: "to the contrary, a Bayesian analysis of the data indicated strong evidence for a null effect."

Quite interesting study which shows you can reconstruct the semantics of experiences while totally bypassing what's known as the "language centers" of the brain using an LLM trained on brain scans. www.science.org/doi/10.1126/...

Happy to have this finally out! TL;DR: The evolution of beliefs over time can be formulated as a dynamical system, and OFC neural activity appears to implement this system with its own dynamics. These emerge without explicit supervision—when animals learn to predict value in simple Pavlovian tasks

Had a UKRI funded grant proposal rejected at the "AI triage stage". "This AI-based triage was used only to identify approximately 50% of the strongest proposals to take forward to full human review." 🧪 #academicsky
I am writing to let you know that, unfortunately, your application was not successful.

Review process

As part of the initial triage of the 179 proposals submitted to this call, each was assessed using an AI-based review. Every proposal was read independently by several different AI models against the same seven criteria used to shape this call (including cyber security relevance, research quality and novelty, importance of the problem addressed, feasibility of the project plan, likely outputs and impact, value for money, and responsible research practice), with each model asked to give a score and a written justification with supporting quotations from the text. To guard against any one model's idiosyncrasies, we also ran a second, independent process in which different AI models debated the merits and weaknesses of each proposal before reaching a judgement, again against the same criteria. Scores from both processes were combined to produce an overall ranking. 

This AI-based triage was used only to identify approximately 50% of the strongest proposals to take forward to full human review.  Projects selected for funding were drawn from those that progressed to the full human review stage. We recognise that AI-assisted assessment is a new and evolving part of the review process, and we are continuing to evaluate how well it aligns with the judgements of human reviewers on this call. We will soon produce a document detailing our method, so that others can build upon it and improve it.

Feedback on your application

Your application was not selected to progress beyond the AI triage stage.  To provide transparency on the outcome of this assessment, we are sharing below the scores (out of 5) from each of the two AI review processes described above, together with the mean score across the two processes.

10/11 In sum, we found a manipulable circuit for top-down control of the heart. We think it's a piece of the foundation for understanding how cognition and emotion shape the body, and a possible target for therapies that restore healthy brain–heart coupling.

9/11 And what about cognition? In a risky decision task, sonogenetic activation of a12 shifted behavior toward uncertain, immediate rewards. Chemogenetic inactivation did the reverse. Off-target ultrasound had no effect.

8/11 Can the circuit be engaged less invasively? We expressed TRPV1 in a12 and stimulated with ultrasound. Heart rate variability rose during stimulation, far more than in TRPV1-negative or off-target controls. Silencing LHA blunted the effect.

6/11 a12 neurons also tracked the heart. A sizable fraction followed spontaneous heart rate fluctuations over seconds, not beat by beat. Some shifted their firing before the heart changed, mostly cells that fire more when heart rate is low.

Yeah I was thinking these are slightly out of reach for most. 24B can run on a 5090 I believe with the right settings, but not well. But presumably one can rent out server time for these models for less per token than OAI and co? Only a matter of time…

It may not be doomsday, and likely with careful measures such as process telemetry (eye tracking, mouse tracking, etc) plus server and client side protections, we can catch many responses. But still, not guaranteed to catch them all, and for how long?

In fact, for many of the well meaning suggestions my post elicited, other experts have pointed out that these are at best imperfect stop gaps. My main take away is that we really need to be aware of these limitations and of the fact that is a quickly escalating situation.

I really appreciate all the discussion and helpful feedback. As many are suggesting adversarial prompt injection its worth noting that there is already empirical research on this which suggest it is only partially effective and highly model dependent.
