Astrocytes and Memory Formation

From encoding to consolidation — an emerging astrocytic role.

Memory formation involves the strengthening of specific synaptic circuits over time. Astrocytes influence this process through modulation of NMDA-dependent plasticity, metabolic support, and possibly by contributing to memory-related network states.

§ 1

Experimental evidence

Activation of hippocampal astrocytes has been shown to enhance memory recall in mice, suggesting a functional role beyond mere support.195


§ 2

Human relevance

Whether the same mechanisms extend to human declarative memory in a comparable fashion is not yet established, but the biological plausibility is strong.
