Research is being conducted on the role of astrocytes in the brain, specifically their involvement in synaptic plasticity. Astrocytes appear to have a complex function, with some studies suggesting they play a role in mediating higher-order control of synaptic plasticity, while others explore their potential impact on brain disorders. The exact nature of astrocytes' influence on the brain is still being investigated, with various studies examining their interaction with neurons and their potential as a target for therapies.
