Mirror Neurons, Motor Ability, and Empathy

Mirror neurons are a type of brain cell that seem to be involved in perceiving the intentions—the mental state—of another person. Mirror neurons are activated or “fire” both when we perform an action and also when we see that action being performed by someone else and it’s been hypothesized that there might be a dysfunction […]

“activates poorly understood ion channels in the brain to alleviate anxiety or depression. This suggests that an entirely new class of depression and anxiety drugs might be right under our noses anxiety and causes other antidepressant activity in the […]
