Brain science is making tremendous advances. It has already had a huge impact of the practice of psychotherapy, and this impact will only grow in the future. I can see a time in which insurers will expect to see progress which is measurable by brain imaging techniques (at this point, mostly fMRI or PET).
Yes, we know that neural networks which are usually formed during infancy do not form in some individuals, often as a result of the infant being neglected. This will result in problems for the individual later in life. Can psychotherapy "rewire " the brain and reverse the physical impact on the brain of an individual's problematic infancy? It can, within limits. An individual can create and strengthen those neural networks which are used during healthy, adaptive thinking, and can engage in that kind of thinking in a therapeutic alliance with a cognitive behavioral therapist, for example.
I posted on this recently on the TER Media discussion board.
You also ask about trauma. Looking at PTSD, we know that some individuals have more genetic susceptibility than others to developing PTSD as a result of trauma, but that does not mean that those with less genetic susceptibility are "invulnerable" to PTSD - if the trauma they experience is sufficiently severe, they will also develop PTSD. The flooding of the brain's HPA with cortisol can overwhelm anyone. However, PTSD can be treated (though not "cured") with Cognitive Behavioral Therapy, usually with a combination of Cognitive Reframing (learning to think about the traumatic experience more realistically) and Exposure Therapy (gradual exposure to "triggers").

I've recently been reading a bit about neural plasticity and find it pretty damn fascinating. Learning about the brain never ceases to excite me.
Now you're talking about adult neural plasticity, and I had been wondering about that. What I have been reading has focused on children and how horrible experiences prior to 3 years old can hard wire a brain to dysfunctionality emotionally and intellectually. I understand that the hard wiring can be undone with extensive and expensive therapy (sometimes successful but more often than not unsuccessful), and I had wondered what would happen if nobody cared and the child grew into an adult and then wanted to make changes. Is it even possible?
Any books you can recommend on the concept of adults and neural plasticity?
Also, can an experience (nurture) create a physical change in the brain even if no genetic predisposition (nature) existed? I am thinking that if an experience is traumatic enough, the brain changes physically regardless of genetic predisposition.
