#Computational #Neuroscience at #Cambridge University and #Intel.

I work on the connection of biological 🧠 and artificial 🤖 intelligence. By building neuro-inspired AI (from prefrontal cortex dynamics and circuit plasticity rules) I try to understand the general principles underlying computation in artificial and biological networks. I work with John Duncan and Matt Botvinick.

Two years ago, Dan Akarca & I wondered: Could the various features we observe in brains across species be caused by shared functional, structural & energetic constraints? 🧠⚡️

With our now published spatially embedded RNNs we show this is true!

At , Jonathan Cornford presented a super cool new :

Synaptic Weight Distributions Depend on the Geometry of Plasticity
https://arxiv.org/abs/2305.19394

Jointly lead with Roman Pogodin, they develop a theory of how a cost function attached to weight changes during learning creates weight distributions observed in biology. Work done in @tyrell_turing group!

the number of ppl perhaps rightly mourning the decay of academic twitter as one of the only ways to share, find and talk about research seems like it points directly to the fundamental hollowness of the current journal system as a means of uh sharing, finding, and talking about research.

our for-profit system of communication is so hostile to the way we want to work that we became dependent on a different, also very hostile informational chokepoint.

I think it is a pretty normal idea to want to try to rebuild our communication systems ourselves, in common. whatever that looks like. I get why that's weird or boring or scary to ppl I just think it would be fun and good to do.

In it’s circuit plasticity all the way down:

“Using long-term exposure to high concentrations of geosmin, an indicator of potentially lethal microorganisms, we demonstrate at the single-cell level that the underlying neuronal circuitry undergoes structural changes in the antennal lobe, while higher brain centers remain unaffected. In particular, second-order neurons show neurite extensions and synaptic remodeling after the exposure period, whereas olfactory sensory neurons and glia cells remain unaffected. Flies that were exposed to geosmin tolerate this innately aversive odorant in general choice and oviposition assays. We show that even a highly specific olfactory circuit is plastic and adaptable to environmental changes.”

From “Experience-dependent plasticity of a highly specific olfactory circuit in melanogaster” by Fabian et al. 2023 (Silken Sachse’s lab) https://www.biorxiv.org/content/10.1101/2023.07.26.550642v1

@albertcardona Albert, a perhaps naive question but it came to mind when skimming the cool paper you linked: If there is experience dependent plasticity even in drosophila, is this plasticity bounded / restricted enough for recent work on high res scans of the drosophila connectome to still be a meaningful representation of the 'expected connectome' in an alive individual? I imagine wiring changes through experience but is still more constrained than what one would expect from e.g. primate PFC?
