(1/n) Thrilled to share my first paper at Meta FAIR! "EgoBabyVLM: Benchmarking Cross-Modal Learning from Naturalistic Egocentric Video Data" 👶 Human infants learn language from sparse, noisy multimodal input. Today's VLMs can't. We built a benchmark + challenge to close that gap. 🧵

We recently investigated how humans and AI reason through causal rules: arxiv.org/abs/2606.06464 Accepted at #CogSci2026. We gave adults and LLMs agency to actively experiment using a Blicket causal game, breaking down their process into the iterative loop shown in the following figure:

Today I received a note from a grad student who lives in Tehran. Her note gives you firsthand experience of what it’s like to live in a city that is being bombed, and what it’s like to be young and feel despair about your future. rezashadmehr.blogspot.com/2026/03/hope...

The revised version of our paper on the impact of top-down feedback is now out @elife.bsky.social: doi.org/10.7554/eLif... tl;dr: we show that using human-brain-like feedback/anatomy in a deep RNN leads to human-like visual biases! This work was led by @tmshbr.bsky.social #NeuroAI 🧠📈 🧪

I’m grateful to share that our paper has been published in Nature. This work formed the core of my PhD research at McGill University. We show that hippocampal neurons that initially encode reward progressively reorganize to reflect predictive representations of reward during learning.

Our paper on the "Oneirogen hypothesis" is now up in its revised form on eLife! This is the hypothesis that psychedelics induce a dream-like state, which we show via modelling could explain a variety of perceptual and learning effects from such drugs. elifesciences.org/reviewed-pre... 🧠📈 🧪

Top-down feedback is ubiquitous in the brain and computationally distinct, but rarely modeled in deep neural networks. What happens when a DNN has biologically-inspired top-down feedback? 🧠📈 Our new paper explores this: elifesciences.org/reviewed-pre...

Excited to share our new pre-print on bioRxiv, in which we reveal that feedback-driven motor corrections are encoded in small, previously missed neural signals.

At #Cosyne2025? Come by my poster today (3-047) to hear how sequential predictive learning produces a continuous neural manifold with the ability to generate replay during sleep, and spatial representations that "sweep" ahead to future positions. All from sensory information alone!

Why does #compneuro need new learning methods? ANN models are usually trained with Gradient Descent (GD), which violates biological realities like Dale’s law and log-normal weights. Here we describe a superior learning algorithm for comp neuro: Exponentiated Gradients (EG)! 1/12 #neuroscience 🧪
