TL;DR: 2 patients who were diagnosed with COVID-19 after presenting with diplopia and ophthalmoparesis are reported, and neurologic complications of CO VID-19 are reported.

TL;DR: This review summarizes and discusses recent findings on the critical role of astrocytes as providers of energy for the long‐lasting neuronal changes that are necessary for long‐term memory formation, and focuses on three main findings: the role of glucose metabolism and the learning‐ and activity‐dependent metabolic coupling between astroCytes and neurons in the service of long‐ term memory formation.

TL;DR: It is shown that repeated exposure to cocaine negatively regulates the active form of Rac1, a small GTPase that controls actin remodeling in other systems, and that Rac1 signaling mediates structural and behavioral plasticity in response to cocaine exposure.

TL;DR: It is shown that astrocytic rather than neuronal β2ARs in the hippocampus play a key role in the consolidation of a fear-based contextual memory, which may represent a novel target mechanism for stress-related psychopathologies and neurodegeneration.

TL;DR: Some new insights that emerged from recent studies implicating astrocytic glycogen and glucose metabolisms, and particularly their coupling to neuronal functions via lactate, as an essential mechanism for long-term memory formation are considered.
