Abstract
Ketamine, a dissociative anesthetic primarily recognized for its antagonism of N-methyl-D-aspartate (NMDA) receptors, has gained significant attention for its rapid antidepressant effects and potential in treating mood disorders. However, recent research indicates that ketamine's influence extends beyond NMDA receptor inhibition, affecting α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors and sensory processing. This review delves into ketamine's role in enhancing AMPA receptor function and its implications for sensory processing within the somatosensory cortex. AMPA receptors, essential for fast excitatory neurotransmission and synaptic plasticity, play a key role in sensory perception and integration. By examining preclinical and clinical studies, this review sheds light on how ketamine's modulation of AMPA receptors may improve sensory processing and contribute to its therapeutic effects. Additionally, the review explores the potential for ketamine-based therapies to treat sensory processing disorders and refine current treatment strategies. A deeper understanding of ketamine's complex effects on AMPA receptors and sensory processing could provide valuable insights for developing targeted interventions and advancing clinical applications.
