Research is exploring the role of astrocytes in the entorhinal cortex-dentate gyrus circuit, which appears to be relevant to cognitive processing and impairment in certain pathologies. Studies are investigating the functions of astrocytes in the hippocampal circuitry, including their involvement in neuronal transmission and behavior. The findings are shedding light on the complex interactions between astrocytes and other components of the hippocampus, with potential implications for understanding various neurological conditions.
