Forceful synapses reveal mechanical interactions in the brain

Communication between neurons in the brain is generally associated with electrochemical signalling. Here we reveal that neurons can also communicate through the force generated by the enlargement of dendritic spines. This force is comparable to that of muscle contraction and might underlie learning and memory, suggesting that brain function is more mechanical than was previously thought.
