Scientists Locate Where the Imagination Works in the Brain
Imagining a bumblebee with a bull's head is a seemingly effortless task, but actually requires the brain to construct an entirely new and unreal image.
What's the Latest Development?
Researchers at Dartmouth University have taken a step toward understanding what sets human intelligence apart, and have located that difference in the neural networks of the brain. In an experiment, individuals were asked to imagine specific shapes and then to mentally combine them into new more complex figures. Imagining a bumblebee with a bull's head, for example, is a seemingly effortless task, but actually requires the brain to construct an entirely new image. "Researchers measured the participants' brain activity with functional MRI and found a cortical and subcortical network over a large part of the brain was responsible for their imagery manipulations."
What's the Big Idea?
Researchers call the neural network that activates when the imagination is at work the "mental workspace," which closely resembles the network thought to be responsible for human consciousness and our flexible cognitive abilities. Lead author of the study, Alex Schlegel, said: "Our findings move us closer to understanding how the organization of our brains sets us apart from other species and provides such a rich internal playground for us to think freely and creatively. Understanding these differences will give us insight into where human creativity comes from and possibly allow us to recreate those same creative processes in machines."

Universities claim to prepare students for the world. How many actually do it?
- Many university mission statements do not live up to their promise, writes Ben Nelson, founder of Minerva, a university designed to develop intellect over content memorization.
- The core competencies that students need for success—critical thinking, communication, problem solving, and cross-cultural understanding, for example—should be intentionally taught, not left to chance.
- These competencies can be summed up with one word: wisdom. True wisdom is the ability to apply one's knowledge appropriately when faced with novel situations.
An increasingly likely catastrophe can cause major disruptions in space flight and our daily lives.
Exploring space is one of humanity’s most hopeful activities. By going out into the great unknown of the Universe, we hope to extend our reach, find new resources and life forms, while solving many of our earthly problems. But going to space is not something to take for granted—it can actually become impossible. There is a scenario, called the Kessler Syndrome, that can cause the end of all space exploration and dramatically impact our daily lives.
A new study may help us better understand how children build social cognition through caregiver interaction.
According to a man that knows more than 20 languages, the key is to start in the middle.
- Canadian polyglot Steve Kaufmann says there is indeed a fast track to learning a new language. It involves doubling down on your listening and reading.
- By taking the focus off grammar rules that are difficult to understand and even more difficult to remember, you can instead develop habits by greater exposure to the language. Kaufmann likens the learning process to a hockey stick.
- In the beginning you make major progress as you climb the steep hill of the hockey stick, whereas the long shaft of the stick is the difficult part. Because you're not seeing day-to-day changes, you might lose motivation. So, stay the course by consuming content that interests you.
