Good readers have distinct brain anatomy, research reveals (psypost.org)
The number of people who read for fun appears to be steadily dropping. Fifty percent of UK adults say they don’t read regularly (up from 42% in 2015) and almost one in four young people aged 16-24 say they’ve never been readers, according to research by The Reading Agency.

Male and female brains are wired differently (earth.com)
Have you ever found yourself in a heated discussion with someone of the opposite sex and thought – “it’s like we’re wired differently”? Well, a recent study from the University of Cambridge suggests that male and female brains are indeed wired differently from the time of birth.

Data from macaque monkeys reveals flaws in deep neural networks (seas.harvard.edu)
Among the marvels of the human brain is its ability to generalize. We see an object, like a chair, and we know it’s a chair, even when it’s a slightly different shape, or it’s found in an unexpected place or in a dimly lit environment.

REM Sleep as a Mechanism to Prevent Takeover of the Visual Cortex (2021) (nlm.nih.gov)
Regions of the brain maintain their territory with continuous activity: if activity slows or stops (e.g., because of blindness), the territory tends to be taken over by its neighbors.

The Vagus Nerve's Mysterious Role in Mental Health Untangled (scientificamerican.com)
The vagus nerve is a vine of nerve fibers with roots in nearly every organ and shoots in the brain. It helps us detect a racing heart, rising blood pressure, stomachache, discomfort, an overzealous immune system and even alarm calls from microbes in our gut. When it senses trouble, the vagus helps to steady our heart, soothe our stomach, rein in our immune system and calm us down.

The Paradoxical Slowness of Human Behavior (caltech.edu)
Caltech researchers have quantified the speed of human thought: a rate of 10 bits per second. However, our bodies' sensory systems gather data about our environments at a rate of a billion bits per second, which is 100 million times faster than our thought processes.

Attention as the management of electromagnetic field lines (qualiacomputing.com)
Try to focus your attention on the exact center of your visual field right now. Notice how the seemingly straightforward task reveals systematic instabilities: wavering, drifting, and transforming in characteristic ways. These effects aren’t random noise; they suggest an underlying physical mechanism that shapes how attention behaves more broadly.
