Prefrontal cortex is an interesting brain area.

You prune away the weaker branches so that the remaining, important branches, can grow stronger, and this process, which effectively fine-tunes brain tissue according to the species-specific environment, is happening in prefrontal cortex and in other brain regions during the period of human adolescence.

So a second line of inquiry that we use to track changes in the adolescent brain is using functional MRI to look at changes in brain activity across age.

So in my lab, we're interested in the social brain, that is the network of brain regions that we use to understand other people and to interact with other people.

So in my lab, we bring adolescents and adults into the lab to have a brain scan, we give them some kind of task that involves thinking about other people, their minds, their mental states, their emotions, and one of the findings that we've found several times now, as have other labs around the world, is part of the prefrontal cortex called medial prefrontal cortex, which is shown in blue on the slide, and it's right in the middle of prefrontal cortex in the midline of your head.

So almost 400 years ago, Shakespeare was portraying adolescents in a very similar light to the light that we portray them in today, but today we try to understand their behavior in terms of the underlying changes that are going on in their brain.

But now we try to understand that in terms of the development of a part of their brain called the limbic system, so I'm going to show you the limbic system in red in the slide behind me, and also on this brain.

So the limbic system is right deep inside the brain, and it's involved in things like emotion processing and reward processing.

So brain research has shown that the adolescent brain undergoes really quite profound development, and this has implications for education, for rehabilitation, and intervention.

The environment, including teaching, can and does shape the developing adolescent brain, and yet it's only relatively recently that we have been routinely educating teenagers in the West.

And yet, this is a period of life where the brain is particularly adaptable and malleable.

It actually reflects changes in the brain that provide an excellent opportunity for education and social development.

So two minutes lead to these hormonal changes that configure your brain to basically be either assertive, confident and comfortable, or really stress-reactive, and feeling sort of shut down.

Configure your brain to cope the best in that situation.

And what they found is that the amygdala, a part of the brain associated in part with fear and anxiety, lit up when people looked at angular objects, but not when they looked at the round ones.

The first is we can now eavesdrop safely on healthy brain activity.

MRIs use magnetic fields and radio waves and they take snapshots of your brain or your knee or your stomach, grayscale images that are frozen in time.

In the 1990s, it was discovered you could use the same machines in a different mode, and in that mode, you could make microscopic blood flow movies from hundreds of thousands of sites independently in the brain.

In fact, the so what is, in the brain, changes in neural activity, the things that make your brain work, the things that make your software work in your brain, are tightly correlated with changes in blood flow.

You make a blood flow movie, you have an independent proxy of brain activity.

Take any cognitive domain you want, memory, motor planning, thinking about your mother-in-law, getting angry at people, emotional response, it goes on and on, put people into functional MRI devices, and image how these kinds of variables map onto brain activity.

Well, your brain has to do something just like that as well, and we're now beginning to understand and identify brain systems involved in valuation, and one of them includes a neurotransmitter system whose cells are located in your brainstem and deliver the chemical dopamine to the rest of your brain.

We have a behavioral superpower in our brain, and it at least in part involves dopamine.

It engages deep systems in our brain, in dopaminergic systems that are there to make you chase sex, food and salt.

We can study the way that one person interacts with another person, turn the numbers up, and start to gain new insights into the boundaries of normal cognition, but more importantly, we can put people with classically defined mental illnesses, or brain damage, into these social interactions, and use these as probes of that.

This one entered her left hemisphere, and knocked out her Broca's area, the speech center of her brain.

Seeing this video of Gabby Giffords reminded me of the work of Dr. Gottfried Schlaug, one of the preeminent neuroscientists studying music and the brain at Harvard, and Schlaug is a proponent of a therapy called Melodic Intonation Therapy, which has become very popular in music therapy now.

Suddenly, what we're finding with these concerts, away from the stage, away from the footlights, out of the tuxedo tails, the musicians become the conduit for delivering the tremendous therapeutic benefits of music on the brain to an audience that would never have access to this room, would never have access to the kind of music that we make.

The synchrony of emotions that we experience when we hear an opera by Wagner, or a symphony by Brahms, or chamber music by Beethoven, compels us to remember our shared, common humanity, the deeply communal connected consciousness, the empathic consciousness that neuropsychiatrist Iain McGilchrist says is hard-wired into our brain's right hemisphere.

Because I want to share with you today a piece of science that has changed how I think about everything, from the behavior of neurotransmitters in our emotional brain, to the dynamics of our interpersonal relationships.
