Researchers at the University of Oxford have developed a groundbreaking technique for 3D printing human stem cells to create an engineered tissue that mimics the structure of the cerebral cortex. How they did it: Using human induced pluripotent stem cells (hiPSCs) — which have the potential to generate most human cell types — the researchers fabricated a two-layered brain tissue. When implanted into mouse brain slices, these 3D-printed tissues managed to demonstrate structural and functional integration.

Ubiquitous bursts of brain waves appear to synchronize different and distant elements of memory, unifying them upon recollection.

Researchers provide some of the first empirical evidence that brain ripples exist. These electrical waves have long been hypothesized as a way for the brain to
