The existing inorganic solid electrolyte membranes typically face challenges such as substantial thickness in the range of hundreds of micrometers and low ionic conductivity.
Large-scale, long-term recordings of the activity of individual brain neurons are essential for improving our knowledge of neural circuits, developing new medical device-based treatments, and, eventually, developing brain-computer interfaces that need high-resolution electrophysiological data.
Human growth hormone derived from cadavers was linked to Alzheimer's disease in five patients who received injections decades ago, a study in Nature Medicine finds.
