Moss Is Generating Electrical Waves That Look Startlingly Like a Neural Network

A study published in Royal Society Open Science reveals that moss cushions (Brachythecium rutabulum) produce complex electrical activity with dynamic wave patterns that undulate across the colony, behaving as spatially distributed excitable systems capable of coordinating and integrating electrical signals across space and time—a discovery that expands understanding of plant communication and information processing in primitive organisms.

The study lacks negative control recordings to rule out artifacts from the electrode method itself.
