The only thing worse than making a mistake is keeping it bottled up inside. Learning from the mistakes of others could help you embark on the healing journey of sharing and working through a mistake of your own, with someone you trust.

Coles' brain was preserved with a slurry of 'cryoprotective' chemicals, and despite expectations of damage, the tissue structure survived with relative vigor.

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.

The condition is described as mental fatigue that can occur when people use AI tools to an extent that exceeds their cognitive capacity. Symptoms can include mental fog, difficulty concentrating, slower decision-making, and sometimes headaches.

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.

In fact, when prompted strategically by researchers, Claude delivered the near-complete text of Harry Potter and the Sorcerer's Stone, The Great Gatsby, 1984, and Frankenstein, in addition to thousands of words from books including The Hunger Games and The Catcher in the Rye. Varying amounts of these books were also reproduced by the other three models. Thirteen books were tested.

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.

It might come as a surprise to learn that the brain responds to training in much the same way as our muscles, even though most of us never think about it that way. Clear thinking, focus, creativity, and good judgment are built through challenge, when the brain is asked to stretch beyond routine rather than run on autopilot. That slight mental discomfort is often the sign that the brain is actually being trained, a lot like that good workout burn in your muscles.

Dementia is linked to changes in the brain. Health professionals used to assume that brain damage and dementia symptoms always went hand in hand. More recent research, however, shows that some people have significant brain damage yet never develop dementia. How can that be? In a previous post, I shared that dementia is defined by the inability to function in everyday life, such as getting lost in familiar places, having difficulty managing finances, forgetting to turn off the stove, or struggling with basic tasks.

The team, which is being led by Jülich neurophysics professor Markus Diesmann, will leverage the Joint Undertaking Pioneer for Innovative and Transformative Exascale Research (JUPITER) supercomputer for their simulation. JUPITER is currently the fourth most powerful supercomputer in the world according to the TOP500 list, and features thousands of graphical processing units. The team demonstrated last month that a " spiking neural network " could be scaled up and run on JUPITER, effectively matching the cerebral cortex's 20 billion neurons and 100 trillion connections.

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.

I am a worrier, and have been for most of my life. At some point, someone dear and smart teased me that I worry about the wrong things. The things that hit me, she noted, were never the things I worried about. For a while that left me feeling like an incompetent worrier-until my research caught up. I realized that the things I worry about often don't end up hurting me precisely because worrying helps me diffuse them ahead of time.
