🧠 New preprint by Tilbury et al: Characterizing #NeuronalPopulation geometry with #AI equation discovery
The approach generates & evaluates 100s of candidate equations, finding "peaky" non-Gaussian tuning functions whose Fourier structure matches power-law dimensionality observed in real #V1 pops. Links shape of single-#neuron tuning to #PopulationLevel geometry using both data fits & analytical derivations.

Charles Micou & Timothy O'Leary discover that representational drift in #neuralactivity and physiological changes, observed over extended periods, suggests the continuous application of a #learningrule at the #cellular and #populationlevel. This phenomenon serves as a measurable signal to uncover system-level properties of biological #plasticity mechanisms, such as precision and effective #learningrates.
