Open Unknowns (3)

Unknown What is the quantitative relationship between sleep deprivation duration and glymphatic CSF clearance rate, and what is the minimum sleep dose needed to prevent net amyloid-β accumulation? u-glymphatic-csf-clearance-sleep-deprivation-rate
Unknown Whether the mathematical equivalence between dense Hopfield networks and transformer self-attention (Ramsauer et al. 2020) implies that biological memory retrieval in the hippocampus operates via a biologically plausible version of the attention mechanism u-hopfield-modern-attention-biological-plausibility
Unknown When, if ever, does frequent cognitive sampling of an internal variable produce measurement-induced stabilization analogous to the quantum Zeno effect, and what experimental designs falsify the analogy? u-quantum-zeno-measurement-neural-interruption

Active Hypotheses

Hypothesis Glymphatic CSF clearance of amyloid-β is primarily driven by slow-wave sleep (SWS) arterial pulsatility, such that each additional hour of SWS produces a quantifiable reduction in CSF amyloid-β concentration predictable from the Biot poroelastic flow model. high
Hypothesis Transformer self-attention is the update rule of a dense Hopfield network with exponential interactions, implying that the biological correlates of attention in the cortex (top-down modulation of sensory processing) and the mathematical correlates of attention in transformers are instances of the same attractor memory retrieval dynamics described by spin glass theory high
Hypothesis Increasing self-report probe frequency over a controlled range will produce a non-monotonic change in the hazard rate of internal strategy switches, consistent with a Zeno-like stabilization regime at intermediate rates in a perceptual discrimination task. medium
