Researchers developed a cable-free recording method that can measure brain activity associated with social behavior in mice. The method was based on a bioluminescent indicator of membrane voltage called 'LOTUS-V', which was delivered to cells via a gene expression system; it is therefore minimally invasive. LOTUS-V enabled cable-free detection of brain activity in freely moving mice. Activation in the primary visual cortex was found during social interaction.
