Social interactions need understanding and awareness of others’ behavior. Studies have proposed mirror neurons, or cells denoting actions by self and others, as critical components for cognitive substrates facilitating understanding and awareness. Primate neocortical mirror neurons are reportedly involved in skilled motor tasks; however, the importance of the neurons for their actions and social interactions is unclear.
To investigate the need for visual input during aggression mirroring, a perforated partition arena was illuminated using infrared light, to which the murine animals were insensitive. Subsequently, the perforated partition was replaced by a solid, transparent partition to decrease demonstrator mice’s pheromone access to observer mice. Further, mini-scope calcium imaging was performed to investigate VMHvlPR neuronal activity during the enactment and observation of aggression.

Visual input, but not prior social experience, was essential for aggression-mirroring by VMHvlPR neurons. The activity of VMHvlPR neurons mirrored aggression between other individuals.
