Imagine discovering that your thoughts, behaviors, and even your personality might be partly controlled by microscopic organisms living inside you. This isn't science fiction-it's the startling reality explored in "This Is Your Brain on Parasites." The natural world is filled with mind-controlling parasites that hijack their hosts' nervous systems with surgical precision. From ants forced to climb grass blades to be eaten by sheep, to rats that lose their fear of cats, these manipulations aren't random accidents but carefully orchestrated behavioral modifications that ensure parasites' survival. What's most unsettling? Humans aren't immune to this manipulation. These invisible puppeteers may be influencing everything from our daily decisions to our cultural institutions, challenging our most fundamental assumptions about free will and identity.
