Our final poster at #SfN2025 explores human-in-the-loop optimization for intracortical microstimulation, presented by @lozaneuro.bsky.social, in collaboration with @umh.es: PSTR450.20 Nov 19 at 1:00 PM www.abstractsonline.com/pp8/#!/21171... #SfN25 #VisionScience #NeuroTechnology

Schematic labeled human-in-the-loop optimization (HILO). It shows two stimuli on the left: pulse trains with varying stimulus amplitude over time. A participant has to choose which stimulus appears brighter. This feedback is used to inform a Gaussian process model that chooses the next stimulus pair, with the goal of finding the stimulus with the lowest overall charge to elicit perception

DAY 15: Advent of Comp Neuro 🎄🤖🧠🧪 Heterogeneity of neural properties can improve some computational functions, but homogeneity also has its advantages! It's complicated 😅 “Neural heterogeneity controls computations in spiking neural networks” @rgast.bsky.social et al www.pnas.org/doi/epub/10....

Figure 1 from Gast et al

Heterogeneity linearizes neural population dynamics. (A–D) Two-dimensional (2D) bifurcation diagrams are depicted for different cell types. Regions colored in gray and green depict bistable and oscillatory regimes, respectively. The black and orange crosses depict approximate bifurcation points, estimated from the dynamics of simulated SNNs with a Lorentzian and a Gaussian distribution of the spiking thresholds, respectively. Spiking neural network dynamics were obtained from simulating networks of = 1,000 neurons connected by sparse, random couplings (coupling probability of 20%) The y-axis on the Left (Right) depicts the width of the Lorentzian (Gaussian) distribution used to generate the SNNs that result on the bifurcation points shown by the black (orange) crosses. (A) Excitatory regular-spiking neurons with low spike-frequency adaptation ( pA). (B) Excitatory regular-spiking neurons with high spike-frequency adaptation ( pA). (C) Inhibitory fast-spiking neurons. (D) Inhibitory low-threshold-spiking neurons.
