New preprint! How can you remember an image you saw once, even after seeing thousands of them? We find a role for humble mid-level visual cortex in high-capacity, one-shot learning. doi.org/10.1101/2025.09.22.677855 🧵🧪1/
Neuronal signatures of successful one-shot memory in mid-level visual cortex
High-capacity, one-shot visual recognition memory challenges theories of learning and neural coding because it requires rapid, robust, and durable representations. Most studies have focused on the hip...

Great article - I remember reading in Newton's biography that he stuck a blunt-end knitting needle between his eyeball and the bone so he could press the back of his eyeball and see colours.
He clearly didn't have any students at that point in his career 🙂

I wrote a post about how cool it is that scientists in the 1800s figured out that our color vision must arise from three types of cells just using clever behavioral experiments (a century before we recorded from the cones in the eye!)

The rod:cone ratio in mice is 33:1, in humans (outside the foveola) is 15:1, but is 1:7 in the 13-lined ground squirrel (13LGS). How is this dramatic shift in the rod:cone ratio achieved?/2

Ooh great paper! Wonder why (rat) mPFC here doesn't contain irrelevant stimulus info ('early selection') but (monkey) PFC in the Mante-Sussillo style task has both ('late selection'). Reminds me of this reply by Flesch et al, discussing differences in irrelevant stimulus info in fMRI vs monkey PFC.

Awesome work from the Runyan lab!
Check out our new paper, that reveals both the striking generality of cortical circuit organization, but also what we think are key differences in the scales of local excitatory and inhibitory networks across cortical areas. www.jneurosci.org/content/45/1...
Local Differences in Network Organization in the Auditory and Parietal Cortex, Revealed with Single Neuron Activation
The structure of local circuits is highly conserved across the cortex, yet the spatial and temporal properties of population activity differ fundamentally in sensory-level and association-level areas....

Motor cortex is responsible for motoric dynamics in striatum and the execution of both skilled and unskilled actions
Nicholas and Yttri find that in the absence of motor cortex, the stratum alone is
not capable of producing goal-directed behavior. Lesions of motor cortex also produce
a freezing of gait-like behavior...

Just finished 'Playing with Reality' by @kellybclancy.bsky.social. Loved it! I picked it up because I thought it was about the history of games, which it is... but it's also so much more than that. Touches upon game theory, minimax, RL, economics, auctions, evolution, Simcity, and more.

It's finally out!
Visual experience orthogonalizes visual cortical responses
Training in a visual task changes V1 tuning curves in odd ways. This effect is explained by a simple convex transformation. It orthogonalizes the population, making it easier to decode.

Is our brain infinitely flexible or constrained? Oby & colleagues cleverly uses BCIs to test what cortical activity can/can't be generated quickly. Highly recommend!
