In a thought-provoking discussion, producer Sindhu Gnanasambandan explores aphantasia, the inability to visualize mental images, alongside neuroscientist Mark Whitman and cognitive neuroscience professor Joel Pearson. They contrast this with Lulu’s experience of hyperphantasia, where vivid imagery shapes her perceptions. The guests dive into how these differences affect memory and emotional responses, and they even touch on groundbreaking research suggesting ways to induce mental imagery in those who can't visualize. It’s a fascinating journey into the mind's eye!

This week, we turn to an expert who tromps the wilds of wordlessness. Lulu’s young son. In this essay, originally published for The Paris Review under the title “The Eleventh Word,” Lulu explores what is lost with the gaining of language. And how, in a very odd way, a fear of confusion and the unknown may begin with the advent of words. The Radiolab sound team brings this piece to life with original music, and at one point the words melt right out of the air. Support Radiolab by becoming a member of The Lab today.
