>(Want to see which parts of the brain are wired into the fear response in your animal? Just inject its amygdala with some RabV CVS-N2c(deltaG)-tdTomato, a heavily nerfed version of the rabies virus that expresses a fluorescent protein, which will conveniently travel backwards across the synapses and infect all the brain circuits that have input onto the fear-processing center, making them light up bright red.)
