How’s your mental health? Wait, don’t answer. Your future mental health practitioner might care less about what you say and more about biomarkers and the circuitry of your brain. Maybe you’ll give a blood test or a saliva sample to go along with some advanced brain imaging. “Scientists have long known that the most forward part of the brain is the seat of higher cognition. But only in recent years have they been able to link certain mental disorders with specific brain circuits, the connections between neurons that are responsible for every one of our thoughts, emotions and actions.” I suppose that all sounds promising, but I think I’d still rather talk about my mother.
