| 0:06.0 | I'm Cody Gough. |
| 0:07.0 | And I'm Ashley Hamer. |
| 0:08.0 | Today you learn about how newborn mammals dream about the world before they enter it. |
| 0:13.0 | Then you'll learn about the stunning amount of work it takes to prepare fossils for research, |
| 0:18.0 | with help from author Caitlin Wiley. |
| 0:20.0 | Let's satisfy some curiosity. |
| 0:22.0 | Baby mice are able to Let's satisfy some curiosity. |
| 0:27.1 | Baby mice are able to move around and take in what they see as they open their eyes for the first time. |
| 0:29.8 | But how? |

| 0:58.0 | How do babies manage to understand what they're seeing when they've hardly ever seen anything. |
| 1:03.6 | The researchers behind this discovery started by using imaging technology to watch the brains |
| 1:08.7 | of newborn mice that hadn't opened their eyes yet. |
| 1:12.4 | What they saw was spectacular. It turns out that there is a |
| 1:16.4 | ton of activity happening in their little baby brains. Some of that activity starts |
| 1:21.4 | near the retina and flows into other parts of the brain. |
| 1:25.0 | That's a little counterintuitive because retinas detect light and the retinas belonging to these |
