"I can look at an object in the world around me, but I can also close my eyes and imagine the object," says Varun Wadia, highlighting the dual capability of visual perception and imagination.

US researchers found that engaging in intellectually stimulating activities throughout life, such as reading, writing or learning a new language, was associated with a lower risk of Alzheimer's disease, the most common form of dementia, and slower cognitive decline. The study author Andrea Zammit, of Rush University Medical Center in Chicago, said the discovery suggested cognitive health in later life was strongly influenced by lifelong exposure to intellectually stimulating environments.

The forgetting curve explains how quickly people lose newly learned information if it is not reinforced. First introduced by Hermann Ebbinghaus in the late 19th century, the Ebbinghaus forgetting curve demonstrates that we forget information quickly after we first learn it, and then the rate of forgetting slows down over time.

If you're going to prioritize one thing for your brain health, make it this: regular aerobic exercise. Multiple large-scale studies show that aerobic exercise doesn't just keep your heart healthy-it directly impacts your brain structure. One year of aerobic exercise in older adults led to significantly larger hippocampal volumes and better spatial memory. Other trials documented that exercise actually slows age-related gray matter volume loss.

You settle in for a quick scroll through your feed, maybe just to unwind for a minute or two. But somewhere between a cooking hack and a clip you've already forgotten, forty minutes vanished. It's all a blur. Welcome to the era of infinite content and finite attention, where our brains are working overtime just to keep up with the deluge.

The human brain is engineered to ignore most of what it sees and hears, according to the neuroscientists I interviewed for the audio original Viral Voices. If that's the case, how are you supposed to make a memorable impression? The empowering news is that if you understand how the brain works, what it discards, and what it pays attention to, you'll be far more persuasive than you've ever imagined. Persuasive people have influence in their personal and professional lives.

Neuroscientists have a name for the brain network that fires up when you're not focused on an external task: the default mode network, or DMN. It's the constellation of regions - the medial prefrontal cortex, posterior cingulate cortex, and angular gyrus among them - that hums to life when you daydream, reflect on yourself, or think about other people's mental states.
