so, the brain is one of the least studied parts of science . Even with all the knowledge of the brain we have about the brain today, we are only able to compile a vague outline. That is why psychology is a Liberal Art, not just a science. As the scientists from the 'Human Brain Project' (commisioned in 2013) puts it:
" We find that the major obstacle that hinders our under
standing of the brain is the fragmentation of brain research
and the data it produces. Our most urgent need is thus a con-
certed international effort that can integrate this data in a uni-
fied picture of the brain as a single multi-level system. To reach
this goal, we propose to build on and transform emerging ICT
technologies...
Modern neuroscience research has already generated huge volumes of experimental data; large-scale initiatives already in progress will produce a deluge of new findings. Even then, however, much of the knowledge needed to build multi-level atlases and unifying models of the brain will still be missing. The first goal for the HBP should thus be to generate and interpret strategically selected data, unlikely to come from other sources. "

There is no area of psychology more affected by this lack of scientific knowledge then mental illness. This is why antidepressants are so over-prescribed, because psychiatrists are forced to group all depressed or anxious peoples into one treatment. In reality, most of these people have very individualized causes to their depression. You see, Our thoughts and behaviors in the present are not natural, but they were caused by memory's of the past which were responsible for conditioning the subconscious mechanism that leads to our behavior or pattern of thought/behavior. This is where psychoanalysis comes in. Because psychoanalysis works from the outside in, and not the inside out, like science, their methods are entirely dependent on the individual. we have to examine an individuals' memorys, impressions, thoughts and behaviors, and by this, avenues of his inner mind can be paved and mapped out by the psychoanalyst. Then, through a delicate choice of words, we talk to him, lead him down certain pathways and thought-patterns, introduce ideas, suggest things, and thus we are able to re-wire his subconscious thoughts and heal him of his ill behavior. Every word is also a memory, or an impression, on our mind. Thus, different words can have different effects on different people. A Psychoanalyst in practice seeks to re-wire someones behaviors through using the subconscious effects that some words or phrases can have.
