Brainless Plant Seems to Count Light, Hinting at Plant Intelligence
A brainless Mimosa pudica plant appears to count light–dark cycles and anticipate light, rather than simply follow a circadian clock. In controlled experiments, the leaves showed predictive movement within 12–24 hour cycles, suggesting non-neuronal cellular mechanisms can support cognitive‑like functions. The researchers call for replication and note potential future applications in plant-based sensing and bio‑computational devices.
