Neuron: Special Issue on Neuroethics

06 February 2019

Global Neuralethics Summit

The brain is special because of the meaning and assumptions about what can be revealed through neuroscience. Neuroscience has become a national funding priority around the globe with a growing cohort of large-scale research initiatives who endeavor to understand the scientific basis of feelings, thinking, and ultimately the mind. Our ever-expanding global neuroscience landscape requires that we, as a society and as scientists, consider the underlying values and ethics that drive brain research across culture and continents.

Neural Electrodes Snake Around Blood Vessels, Up Nerves

Shape-memory materials could make medical devices longer lasting and easier to implant.

Getting neurons to communicate with electronics has always been hard—hard on the neurons, that is. Arrays of rigid metal electrodes implanted in the brain pierce blood vessels and dislodge support cells, causing the body to cover up the array with an insulating scar, which prevents many incoming signals from getting through. Engineers now think shape-memory materials could do the job much better, because they can be programmed to snake around blood vessels and climb nerves like a vine.
