Conversations with friends have an ease that is hard to replicate with someone you have just met—often replies come more naturally and timing just seems to click. A strikingly similar pattern plays out in zebra finches, very sociable songbirds whose back-and-forth chatter with familiar individuals can take a noticeably different rhythm to exchanges with strangers. Now, researchers at the Max Planck Institute for Biological Intelligence have uncovered how this communication pattern is reflected in the brain, showing that social context influences the activity of neurons involved in vocal communication. The study has been published in PLOS Computational Biology.
