The word "brain" tends to be used when people talk about anatomical structures or circuitry in the brain. The term mind tends to be used to refer to the subjective cognitive states a brain creates. For example, the prefrontal cortex is an anatomical part of the brain, but attention is a cognitive "state of mind" produced by activity in the brain. Generally, we use these terms interchangeably. We consider "nonconscious processes in the brain" to be equivalent to "the nonconscious mind."
