00:04Our brains hold a map of everything we know and experience, right?
00:07So does that mean if we could read that map, we could see everything we know?
00:10Well, that's what neurobiologists say they may be able to achieve,
00:13and their discovery seems to reveal how human beings internalize physical space.
00:17According to the research, when you enter a new space,
00:20your brain collects neurons to create a physical memory of that space.
00:23Science Alert reports those neurons are then arranged into networks called place fields,
00:27full of place cells, so researchers tracked the neural activity of rats as they experienced a new space,
00:32then modeling that activity using geometric mathematics.
00:35They came up with something that looks like this in a 2D space,
00:38though if this were 3D, each triangular subsection would actually be the same size.
00:42As the mice moved through the space, place cells were immediately created,
00:45then growing more detailed and becoming more complex as more information was taken in about the space.
00:50With the researchers writing about it, quote,
00:52Our study demonstrates that the brain does not always act in a linear manner.
00:55Instead, neural networks function along an expanding curve,
00:59which can be analyzed and understood using hyperbolic geometry and information theory,
01:03meaning we're finally getting an esoteric understanding of just how our brains understand space,
01:08bringing us one step closer to unraveling a map of our memories.
01:11Now being able to create a machine,
01:16You're going to take over time for a while.
