The points below describe early belief in the possibility that SARS-CoV-2 can directly infect neurons or glia:

• there is low-level expression of ACE2 in human middle temporal gyrus, posterior cingulate cortex, astrocytes, and oligodendrocytes as well as in artificial stem-cell derived neurons However, these conclusions are drawn upon studies assessing the presence or absence of ACE2 expression, without any functonal data for support.
