Video TranscriptSTILL SHOT of Dr. Rose
GRAPHIC OVER: David H. Rose, Chief Scientist of Cognition & Learning, CAST
Dr. Rose: [gestures with hands] As I’ve said, the brain is one big integrated network, but for convenience, we often think of three different, uh, groupings within that network.
FADE TO Graphic: Networks of the Brain
Dr. Rose [V.O.]: The first are recognition networks, second are strategic networks and the third are affective networks.
[Graphic lists: Recognition, Strategic, and Affective as they are mentioned by Dr. Rose]
[Head shot of Dr. Rose] The first is the part that’s in the [raises his hands even with his head] back of your head, and that part
FADE TO: Illustration of human brain on screen with graphic: Recognition Networks
Dr. Rose [V.O.]: is where all of the axons that come from your sensory organs─your eyes, your ears, your nose, your throat─so the back part of your brain is a big pattern recognition network.
[Wide head shot of Dr. Rose, with graphic under: Recognition Network, Processes patterns] All those axons race to the back of your brain, where they end in cortex that analyzes: What’s the pattern that’s coming in from your eyes and your ears and so on?
[Close head shot of Dr. Rose, same graphic] It’s about recognizing the, what a Buick looks like, uh, what the sound of a piano is or a Beethoven symphony, the smell of coffee. The [wide head shot of Dr. Rose same graphic] whole back half of your brain is designed to process and figure out oh, that’s the coffee pattern, oh that’s the Buick pattern, oh that’s the Beethoven pattern. Those patterns are, are difficult. It takes a while to learn them, and it takes the whole back half of your brain to do that processing.
FADE TO: Illustration of brain with graphic: Strategic Networks.
Dr. Rose [V.O.]: The front half of our brain is another kind of network. I’m going to call it strategic networks. Strategic networks have a different anatomy and a different function.
[Head shot of Dr. Rose, gesturing] The primary feature of the strategic networks is that axons leave and go out to muscles. And the front part of your brain allows you to move, [Fade in graphic: Affective Network, Processes actions and plans] to do skillful things like dance or shoot baskets, and to make plans for actions so that you plan to go the store, and you figure out the route and all of that. So the front part of the brain does that for you. It’s strategic in that it gives you not only actions, but the plans for actions.

Dr. Rose [V.O.]: The third kind of network, affective networks, [Graphic above brain illustration appears: Affective Networks] have to do with emotion, what things make us fearful, what things make us excited, what things appear novel to us.
[Head shot of Dr. Rose] Its function is not to recognize patterns, or to generate patterns of activity, but to evaluate [Graphic appears under Dr. Rose: Affective Network, Processes emotions, evaluates patterns] patterns, to identify what’s important to this whole brain network. What should be focused on, what’s the kind of action that’s the most important to take?

Dr. Rose [V.O.]: In each of the networks, that I’ve talked about [Graphic changes to Strategic Networks] [Graphic changes to Affective networks] there are individual differences.
