Ketamine has emerged as a rapid-acting antidepressant that challenges classical monoaminergic frameworks and highlights the importance of synaptic and circuit-level plasticity in mood regulation. This review examines the hippocampus as a key site through which ketamine exerts both rapid and sustained antidepressant effects. We synthesize evidence showing that ketamine enhances hippocampal...
