- 🧠 New preprint: we show that model-guided microstimulation can steer monkey visual behavior. Paper: arxiv.org/abs/2510.03684 🧵
- Stimulate high-level vs early visual cortex Visual prosthetics in early visual areas can evoke simple percepts (letters), but they are limited by 1. electrode count and 2. low-level features. We target high-level cortex to elicit percepts of more complex objects.
- How it works 1. Map the in-silico cortical sheet of a topographic model to the monkey cortex. 2. Optimize stimulation parameters by prototyping experiments in the model. 3. Only test those parameters in-vivo that are predicted to yield the largest behavioral effects.
- View full thread
- Take-home-message Proof-of-principle that topographic models can guide stimulation of high-level cortex to bias object-level behavioral choices. A step toward next-generation visual prosthetics allowing ore complex visual experience.
- Very happy to be part of this project: Melika Honarmand has done a great job of using vision-language-models to predict the behavior of people with dyslexia. A first step toward modeling various disease states using artificial neural networks.
- I've been arguing that #NeuroAI should model the brain in health *and* in disease -- very excited to share a first step from Melika Honarmand: inducing dyslexia in vision-language-models via targeted perturbations of visual-word-form units (analogous to human VWFA) 🧠🤖🧪 arxiv.org/abs/2509.24597

- Reposted by Hannes MehrerGreat work. We see that if you model Dale's law and Local inhibition, predictions of opto perturbations are improved without including them as training data. www.biorxiv.org/content/10.1... These hybrid mechanistic + data constrained model, seem promising to predict the effect of perturbations

- Reposted by Hannes MehrerIt depends on how extensive you think "*training* on interventional data" will have to be. Eg, topographic models with a simple "perturbation module" to describe the change in neural activity from interventions were quite powerful in predicting behavioral effects www.biorxiv.org/content/10.1...
- Reposted by Hannes Mehrer@kordinglab.bsky.social has convinced me on this point. I am a strong believer in the potential for foundation models to have a big impact in neuroscience. But, if we want to use them as "digital twins" to predict the impact of treatments, we'll need to train them on interventional data. 🧠📈 🧪
