“Dormio takes dream research to a new level, interacting directly with an individual’s dreaming brain and manipulating the actual content of their dreams,” says Robert Stickgold, director of the Center for Sleep and Cognition at Beth Israel Deaconess Medical Center.

MIT engineers have designed a “brain-on-a-chip,” smaller than a piece of confetti, that is made from tens of thousands of artificial brain synapses known as memristors — silicon-based components that mimic the information-transmitting synapses in the human brain. The researchers borrowed from principles of metallurgy to fabricate each memristor from alloys […]

Animation Rife with obstacles and occlusions, terrestrial environments potentially helped give rise to planning circuits in the brain. New simulations show that living among land’s rich topography forced animals to plan rather than act based on habits Planning abilities increased survival rates, so evolution might have selected for brain circuitry […]

Animation States that resemble sleep-like cycles in simulated neural networks quell the instability that comes with uninterrupted self-learning in artificial analogs of brains. No one can say whether androids will dream of electric sheep, but they will almost certainly need periods of rest that offer benefits similar to those that […]

Three-dimensional virtual reconstruction of the braincase of the ankylosaur Bissektipelta archibaldi. Bones are semi-transparent and the internal contents of the endocranial cavity are seen. Pink — inner ear, yellow — nerves, red — major arteries, blue — veins and small arteries, light blue — endocranial cast. Credit: Image provided by […]

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 […]

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 […]
