Understanding the elusive mechanisms responsible for the therapeutic efficacy of ketamine in major depressive disorder (MDD) is crucial. Astrocytes play a vital role in regulating extracellular potassium concentration ([K+]o), which is essential for maintaining proper neuronal excitability and overall brain function. Dysregulation of [K+]o can lead to significant changes in neuronal activity,...
