Discover how the parasite Toxoplasma gondii, often associated with cats, may be subtly influencing human behavior and health. This episode delves into the science behind T. gondii, a protozoan parasite capable of infecting nearly all warm-blooded animals, including humans. Learn how this widespread parasite-estimated to affect up to 50% of the global population-can alter neurotransmitter levels, potentially leading to changes in risk-taking behavior, reaction times, and even attractiveness. We explore its complex life cycle involving cats as the definitive host, the ways it can be transmitted to humans, and its possible links to conditions like schizophrenia and increased risk of certain behaviors. The episode also provides practical tips on prevention and addresses common misconceptions about toxoplasmosis.
