Does Alzheimer’s Disease Start Inside Nerve Cells?

Amyloid-beta accumulates in nerve cells and spreads, from cell to cell, via nerve fibers. This process occurs prior to the formation of amyloid plaques in the brain. from Neuroscience News https://ift.tt/3getqZ0

Researchers Develop the First Steerable Catheter for Brain Surgery

Researchers have developed a new, flexible and steerable catheter that allows surgeons to guide the device in any direction while traversing the brain's arteries and blood vessels. from Neuroscience News https://ift.tt/3mdPNBO

First 3D-Bioprinting of Entire Active Brain Tumor

Researchers have successfully replicated an entire, viable glioblastoma brain tumor via 3D bioprinting. The bioprinted tumor includes a complex system of blood vessel-like tubes through which blood cells and drug molecules can flow, simulating a real tumor. from Neuroscience News https://ift.tt/2W0KvPA
