Early founder of psychology

It's interesting to me that an important early founder of psychology, Sigmund Freud, thought of all of our behaviors as having unconscious origin and repressed impulses and thoughts (Burger, 2017). This runs parallels to the concept of how cognitive processes, unconscious and involuntary, affect our thoughts and behaviors. Freud was a neurologist, yet by the time he died in 1939, technology had not yet been developed to fully show the connection between thought, behaviors, and involuntary neural acticity (Burger, 2017). What do you think Freud would have thought about the discoveries of neuroscience? Would it change his view of the subconscious, ego and id, or would it reinforce his theories of motivation and behavior?
