animation Billiard-like break shot to cell-membrane structures triggers brain’s loss of consciousness from anesthesia, scientists find. Surgery would be inconceivable without general anesthesia, so it may come as a surprise that despite its 175-year history of medical use, doctors and scientists have been unable to explain how anesthetics temporarily render […]

Frontoparietal activation reflects individual working memory abilities. Credit: Rosenberg et al., JNeurosci 2020 Brain network activity predicts working memory abilities during development. A child’s unique brain activity reveals how good their memories are, according to research recently published in JNeurosci. When you scramble to remember a phone number as you enter […]

Visualizations of brain endocasts (blue) from the skulls of a dinosaur and a modern bird.

An international team of evolutionary biologists and paleontologists have reconstructed the evolution […]

Scientists have discovered an earlier origin to the human language pathway in the brain, pushing back its evolutionary origin by at least 20 million years. Previously, a precursor of the language pathway was thought by many scientists to have emerged more recently, about 5 million years ago, with a common […]

Reconstructed sagittal 5-mm orthogonal midline images in the brain using the sagittal three-dimensional T1weighted data set. (a) Preflight baseline image and (b) matching postflight image (postflight day 1) in the same astronaut. The black arrowheads show upward expansion of the anterior, middle, and posterior superior margins of the lateral ventricle […]

A new form of magnetic brain stimulation rapidly relieved symptoms of severe depression in 90% of participants in a small study conducted by researchers at the Stanford University School of Medicine. The researchers are conducting a larger, double-blinded trial in which half the participants are receiving fake treatment. The researchers […]

Stanford researchers used advanced microscopy and mathematical modeling to discover a pattern that governs the growth of neurons in the flatworm brain, shown here. Using this technique, they hope to find patterns that guide the growth of cells in other parts of the body in order to pave the way […]

The shared brain asymmetry pattern is visualized on a human endocast (cast of the internal bony braincase) in lateral view (left) and from the lower side (right). This pattern includes a more backwards projecting left hemisphere and a more forward projecting right hemisphere with localized larger surface areas (orange) in […]
