Novel, ring-inserts' are prepared (1) and loaded with growth factors of interest using microcontact printing (2). Brain slices taken from postnatal day 8-10 mice are added (3) and nerve fibers grow ...

A tiny stack of printed nanomaterials, thinner than a human hair and flexible enough to bend with living tissue, just did something no fabricated device has done before: it fired electrical spikes so ...

Scientists using living human brain tissue have shown for the first time how a toxic form of a protein linked to Alzheimer's can stick to and damage the connections between brain cells. Small pieces ...

Researchers have developed a suite of free tools for analyzing vast amounts of brain dissection photographs at brain banks worldwide to enhance understanding of neurodegenerative diseases. The study, ...

A squishy, fatty, beige-colored organ covered with grooves and ridges, the brain doesn’t look all that impressive on the surface. But hidden underneath are up to 100 billion neurons and 100 trillion ...

Researchers have produced an engineered tissue representing a simplified cerebral cortex by 3D printing human stem cells. When implanted into mouse brain slices, the structures became integrated with ...

Floating in a warm, nutritious bath, the slices of mouse brain buzzed with electrical activity. Researchers gave them a few zaps, and parts of the hippocampus strengthened their wiring. This type of ...
