“I Got a Mind to Tell You” is a new blog by Joe. The goal is cut through the hype and provide straight talk about the brain. These days, there’s way too much unconstrained speculation that masquerades as fact. Dopamine in not the chemical of pleasure. Serotonin does not make your sad. Mental problems are not simply due to chemical imbalances. The right hemisphere is not the seat of creativity. The amygdala is not the wellspring of fear.
