What happens when the brain loses a hub?

<p>A University of Iowa-led team of international neuroscientists have obtained the first direct recordings of the human brain in the minutes before and after a brain hub crucial for language meaning was surgically disconnected. The results reveal the importance of brain hubs in neural networks and the remarkable way in which the human brain attempts to compensate when a hub is lost, with immediacy not previously observed. </p>

Blind man has sight partly restored after pioneering treatment

Last modified on Tue 25 May 2021 00.08 EDT A blind man has had his sight partly restored after a form of gene therapy that uses pulses of light to control the activity of nerve cells – the first successful demonstration of so-called optogenetic therapy in humans. The 58-year-old man, from Brittany in northern France, was said to be “very excited” after regaining the ability to recognise, count, locate and touch different objects with the treated eye while wearing a pair of light-stimulating goggles, having lost his sight after being diagnosed with retinitis pigmentosa almost 40 years ago. The breakthrough marks an important step towards the more widespread use of optogenetics as a clinical treatment. It involves modifying nerve cells (neurons) so that they fire electrical signals when they’re exposed to certain wavelengths of light, equipping neuroscientists with the power to precisely control neuronal signalling within the brain and elsewhere.
