Plants Count Without Neurons

A reported experiment on Mimosa pudica found anticipatory leaf movements that correlate with the number of recent light–dark events and follow a logarithmic learning curve. The authors argue the pattern implies event‑tracking or 'counting' by non‑neuronal cells, suggesting information processing mechanisms beyond neurons. — If true, this reframes cognition as a broader biological phenomenon, affecting neuroscience, AI metaphors, and public views on intelligence and learning.
