The study doesn't address how synapses or other neuronal features can hold this second level of working memory, or how much information it can store.

By contrast, in progressive MS, the blood–brain barrier remains intact, confining the inflammation to the brain, which fuels atrophy and neuronal loss.

These breaks might be the result of physiological processes: DNA breaks arise in response to neuronal activity, although amyloid-β can exacerbate the damage88.
