Алгоритмы сна: почему мозг «оптимизирует» ресурсы именно так, а не иначе

Эта статья появилась у меня не из научной злости и не для демонстрации умных слов, а чтобы вы улыбнулись и отвлеклись от бесконечных тасков и дедлайнов. Сон — это ведь не только про отдых. Это nightly build организма, где мозг одновременно админ, тестировщик и аналитик. Я попробую рассказать о фазах сна так, будто это техпроцесс с пайплайнами, кешами и кодом. Возможно, где-то вы узнаете себя и свои проекты.

🧠 Pastorelli et al. (2025) present a "simplified two-compartment #neuron with #CalciumDynamics capturing #brain-state-specific apical-amplification, -isolation and -drive". This Ca-#AdEx model replicates distinct #dendritic mechanisms across wakefulness, #NREM & #REM sleep using a compact ThetaPlanes transfer function. Cool implementation using the #NESTsimulator 💻!

Figure 1. Brain-state specific apical mechanisms in pyramidal neurons. (A) Cortical pyramidal cell. Green: soma and (peri)somatic dendrites. Orange: apical dendritic tuft. Gray: apical dendrite. Black: axon. Inputs from other areas, representing internally generated priors and top-down signals from areas higher in the hierarchy are segregated to touch the apical tuft (light red arrow). Sensorial evidence and input from areas at lower hierarchical levels (light blue arrow) target the somatic/perisomatic zone together with local signaling (green arrow). (B) During wakefulness, the AA mechanism signals the temporal coincidence of (peri-)somatic and apical inputs by emitting high-frequency burst. (C) In deep-sleep, AI induces the soma to ignore apical signals. (D) When dreaming, AD induces a multi-areal integration driven by internal imagery in absence of sensorial inputs.
