Career choice based on the following criteria...

I would like suggestions as to which career would most align with some of my preferences as I am just beginning an scratch the surface of what interests me in a profession. That being said, I am definitely looking for a profession dealing with the human mind and brain functions. I have included some examples from TV which have really piqued my interest in terms of what I would really enjoy studying.

EX 1: (Big Bang Theory)
Amy: So says your prefrontal cortex. But meanwhile, the limbic system of your brain is calculating that if another woman is attracted to Leonard, it must be because he’s desirable.

EX 2: (Big Bang Theory)
Penny: Right, okay. What was he like when he was young?
Beverley: You’ll have to be more specific.
Penny: Oh, um, okay, like, five or six. Five.
Beverley: Oh, well, at that age he was well enmeshed in what Freud would call the phallic stage of psychosexual development. An outmoded theory, of course, but the boy did spend most of his waking hours with a tight grasp on his penis.

EX 3: (Big Bang Theory)
Penny: Oh, well, I’m an actress.
Beverley: Why?
Penny: What do you mean why?
Beverley: Well, there are studies that suggest that many who go into the performing arts suffer from an external locus of identity.
Penny: Yeah, I don’t know what that means.
Beverley: Well, it means you value yourself only as others value you, which is often the result of unmet childhood emotional needs.

EX 4: (Big Bang Theory)
Leonard: Howard lives with his mother and Raj can’t speak to women unless he’s drunk. Go.
Beverley: That’s fascinating. Selective mutism is quite rare. On the other hand, an adult Jewish male living with his mother is so common it borders on sociological cliché.
Howard: It’s just temporary, I pay rent.
Leonard: He lives in the same room where his bassinet was.
Beverley: You know, both selective mutism and an inability to separate from one’s mother can stem from a pathological fear of women. It might explain why the two of you have created an ersatz homosexual marriage to satisfy your need for intimacy.

EX 5: (The Red Dragon by Thomas Harris)
"Dr. Bloom said the Tooth Fairy’s acts and his letter indicated a projective delusional scheme which compensated for intolerable feelings of inadequacy. Smashing the mirrors tied these feelings to his appearance. The killer’s objection to the name “Tooth Fairy” was grounded in the homosexual implications of the word “fairy.” Bloom believed he had an unconscious homosexual conflict, a terrible fear of being gay. Dr. Bloom’s opinion was reinforced by one curious observation at the Leeds house: fold marks and covered bloodstains indicated the Tooth Fairy put a pair of shorts on Charles Leeds after he was dead. Dr. Bloom believed he did this to emphasize his lack of interest in Leeds. The psychiatrist talked about the strong bonding of aggressive and sexual drives that occurs in sadists at a very early age. The savage attacks aimed primarily at the women and performed in the presence of their families were clearly strikes at a maternal figure. Bloom, pacing, talking half to himself, called his subject “the child of a nightmare.”

So I would guess that the recurring theme from these examples is the great overall understanding of human behavior/ and the brain. However, only the first example directly talks about the brain itself. So I was curious as to which career and/or field of study would allow me to apply both of these topics. Would it just be neuropsychology maybe? let me know what you guys think.

Thanks in advance for any constructive answers.
