The trial-to-trial variability of neuronal responses and the correlated response variability among neurons are modulated by visual stimulus size in a manner that depends on cortical layer, suggesting ...

The study provides new insights into the functions of ancestral cortices but also raises fundamental questions about how and when key neural computations evolved in turtles.

People with aphantasia have no mental imagery—and they’re offering brain scientists a window into consciousness ...

AI algorithms have demonstrated a sensitivity of approximately 91% in detecting early dental caries, compared to 84% for ...

The evidence is solid but not definitive, as the conclusions rely on the absence of changes in spatial breadth and would benefit from clearer statistical justification and a more cautious ...

People with obsessive-compulsive disorder (OCD) can track complex tasks, but it’s harder to switch between them. Their brains ...

Expert birdwatchers have changes in their brain structure compared with novices, which probably help them better identify birds and may even protect against age-related cognitive decline ...

Science says our attention spans are drastically reduced, with one study showing it's now shorter than a goldfish's.

Many older adults struggle with sleep as their brains fail to switch off, a study reveals. Insomniacs' brains remain alert due to a flattened circadian rhythm and persistent sequential thinking, ...

Explore the parallels and differences between AI architectures and the human brain's design and functionality in processing ...

That hollow tiredness after scrolling isn't laziness — it's your brain recovering from thousands of invisible micro-decisions engineered to feel like nothing, each one quietly draining the same ...
