It's not a mistake but one funny part of my job is seeing patients when they wake up from anesthesia. Further perplexing neurologists and neuroscientists are the unknown ways that COVID-19may be impacting the brain directly.

Emery Brown, professor of medical engineering and neuroscience at Massachusetts Institute of Technology, likened the cognitive effects of coronavirus to those seen when patients awaken from.
