Astrocytes, like neurons, would also store memories

Until now, memories have been explained by the activity of neurons that respond to learning events and control recall. A study published in Nature changes this theory by showing that non-neuronal cells in the brain called astrocytes - star-shaped cells - also store memories and work in concert with clusters of connected neurons called engrams to regulate the storage and retrieval of memories.

Reactions: brain health of patients hospitalized for covid worsened similar to that of others admitted with similar severity

A study carried out in two hospitals in Denmark has compared the brain health of 120 patients admitted for covid over 18 months with that of other hospitalized patients with similar severity due to pneumonia, heart attack or need for intensive care, as well as with healthy people. The conclusions are that patients with covid worsened with respect to the latter, but did so in a similar way to other hospitalized persons. According to the authors, "although studies are needed to confirm these findings, brain health after covid-19 appears generally comparable to that of other diseases of similar severity."
