The "software" of the conscious mind, including the executive functions, beliefs, preferences, and in general, is about character maturity.

Its operations have directives, integrated with the five senses, geared toward decoding the world around us, finding the way to goals that we want to accomplish, the higher brain has a sense of linguistics and story to it, which helps us reliably predict future probable outcomes for decisions that we make today.

The higher brain might then be said to house our "personal growth," and in more psychological terms, our character maturity, which as core, prominent functions, include that of Observing Ego, the only learned human personal growth skill which helps us tolerate change and growth, avoiding regrets.

The higher brain also has the other most prominent and sensitive feature of one's character maturity, in the form of personal boundary function.

In Romantic Dynamics, we envision two types of boundary which demarcate the reptilian brain versus the mammalian brain, versus the higher brain, with the personal boundary mediating interactions with the outside world, its stresses and goals of rewards we seek, but an "inner" ego boundary, which demarcates the border between the unconscious and the "preconscious" or conscious minds. As such, the workings of these two kinds of boundaries are central to the explanation of what is actually happening in the ego defenses or defense mechanisms, which help us gauge maturity level.

These intellectual features help us attract the opposite sex by way of our intellect and character, our charm, sophistication and potential partnership aspects that others may pick up on. Emphasis is less about the body and more about words, intentions, tendencies and reliability and loyalty of behavior.

In the field of Evolutionary Psychology, the model called the "Triune Brain Model" has the higher brain as one of the three, interdependent areas of the mind.  These are the Reptilian Brain and the Mammalian Brain.
