Galen Buckwalter, a 69-year-old research psychologist and quadriplegic, participated in a brain implant study to contribute to science that aids those with paralysis. The six chips in his brain decode movement intention, allowing him to operate a computer and feel sensations in his fingers again.

Dr. Conor Boland explained that red-light timing can erase small speed advantages, allowing a slower car to catch up again and again. He noted, 'You pass a car, and then a few minutes later, it ends up beside you again.' This phenomenon is partly psychological, as we remember surprising moments when the same car shows up again, but it is also built into how traffic works.

Our eyes—which we usually think of as purely visual organs—spontaneously dance to the rhythm of what we hear, says study co-author Du Yi, a cognitive neuroscientist at the Chinese Academy of Sciences in Beijing. Using a high-speed eye-tracking system, Du and her team were stunned to discover nonmusicians instinctively blinking in sync with the beat structure of Bach chorales.

They created an artificial 'mental map', with pleasantness along one axis and bodily reactions along the other, and charted how the brain responded while watching clips from films. The results revealed clear groupings in the way that our brains represent emotion - with guilt, anger and disgust in one corner and happiness, satisfaction and pride in the other.

The illusion is the latest masterpiece from Olivier Redon, a French-American inventor, who has had his creations used in museums and on TV programmes around the world. For today's puzzles, I present five of Redon's most brilliant images. The challenge is to figure out how he managed to create them.

For many of us, that compulsive need to touch isn't about poor impulse control. It's about confirmation. It's about making sure the world around us is real, solid, tangible - because somewhere along the line, we learned that the emotional landscape we navigated wasn't.

If we told them to look at the face, they could usually manage it. But they were mostly looking at the hands. The Prakash children eventually learn to look at faces when spoken to - usually a few months after their surgeries. Their experiences reveal that seeing doesn't come naturally the moment a person is cured of blindness. Newly-sighted people must learn to see.

Unlike sight or sound, smell has a direct pathway to the amygdala and hippocampus-the regions involved in emotion and autobiographical memory. Because of this connection, memories triggered by scent are often more vivid and emotionally intense than those triggered by sight.

Accomplishment Hallucination is a cognitive state in which speed feels like competence, output feels like accomplishment, and work feels done when the actual work-the thinking-through, the failure-mode analysis, the sitting with uncertainty until the problem reveals its structure-hasn't happened at all. Physics need not apply. AI can create a similar state in waking life—literally, as your very words assume form before your eyes like a conjuring sorcerer. But, like real life, the code may be buggier than we realize.

At a time when memories are increasingly flattened into folders, feeds, and cloud backups, a new experimental device from MIT Media Lab proposes a far more intimate archive: scent. Developed by Cyrus Clarke, the Anemoia Device is a speculative yet functional prototype that translates photographs into bespoke fragrances using generative AI, inviting users not to view memories, but to inhabit them through the body.

One scientist at MIT, Cyrus Clarke, is working to do just that. Alongside a team of fellow researchers, Clarke has developed a physical machine called the Anemoia Device, which uses a generative AI model to analyze an archival photograph, describe it in a short sentence, and, following the user's own inputs, convert that description into a unique fragrance. The word "anemoia" was coined by author John Koenig and included in his 2021 book, The Dictionary of Obscure Sorrows.

Artificial intelligence (AI) machine learning is making a difference in assistive technology to help restore movement for the paralyzed. A new study in the American Institute of Physics journal APL Bioengineering shows how AI has the potential to restore lower-limb functions in those with severe spinal cord injuries (SCIs) by identifying patterns in brain signals captured noninvasively via electroencephalography (EEG).

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.

Real estate with ocean views, stunning mountain vistas, and wide-open green spaces sell at premium prices because humans find those settings pleasing [1-5]. Certain color combinations in fashion-such as brown and forest green-blend harmoniously, while others, such as hot pink and orange, clash. And our eyes like certain proportions in visual objects (like buildings and human faces) but not others.

Close your eyes and picture an apple. Most people see something-a faint, slightly blurry image, less vivid than a real apple. A few, however, will see it as clearly as if it were sitting right in front of them. This ability is called hyperphantasia. Hyperphantasia, literally meaning "beyond imagination," refers to exceptionally vivid mental imagery. It is often described as the opposite of aphantasia, a condition in which people report little or no ability to form mental images.

Did someone with spatial-sequence synaesthesia design the calendar app on mobile phones? Because that's how time and dates look in my brain. If you say a date to me, that day appears in a grid diagram in my head, and it shows if that box is already imprinted with a holiday, event or someone's birthday. Public holidays and special events like Christmas and Easter are already imprinted for the year, and the diagram goes backwards to about 100,000BC

In 2011, researchers Jason Tangen, Sean Murphy, and Matthew Thompson at the University of Queensland discovered a striking visual illusion while preparing a set of face images for a study. As they were going quickly through the faces to check their spatial alignment, they started noticing that the faces appeared highly distorted, almost cartoonish. They then realized that these distortions were most pronounced when the faces were flashed about 4-5 times per second in peripheral vision.
