- Reposted by Mashbayar TugsbayarOur 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... 🧠📈 🧪

(A collab led by the Trenholm lab) We tried to bring the experience of experimental neuroscience to a classroom setting: www.eneuro.org/content/13/1... #neuroscience 🧪
- Reposted by Mashbayar Tugsbayar🚨 New preprint alert! 🧠🤖 We propose a theory of how learning curriculum affects generalization through neural population dimensionality. Learning curriculum is a determining factor of neural dimensionality - where you start from determines where you end up. 🧠📈 A 🧵: tinyurl.com/yr8tawj3

- 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...
- What does it mean to have “biologically-inspired top-down feedback”? In the brain, feedback does not drive pyramidal neurons directly, but it modulates the feedforward signal (both multiplicatively and additively), as described in Larkum et al 2004.
- Reposted by Mashbayar TugsbayarExcited 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.

- Reposted by Mashbayar TugsbayarAt #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!
- Reposted by Mashbayar TugsbayarVery excited for the upcoming Cosyne in Montreal! I’ll be presenting my poster [2-126] Brain-like neural dynamics for behavioral control develop through reinforcement learning, on the Friday session at 13:15. Feel free to drop by! The related pre-print is also out: www.biorxiv.org/content/10.1...
