Brain stimulation prevents neural downregulation and optimizes learning.
NeuroImage·April 1, 2026·PMID 41724411
Why it mattersCognitive training often fails to produce behavioral gains due to rapid neural adaptation in higher-order attentional areas. This study provides mechanistic evidence that tRNS can sustain cortical excitability during learning, offering a potential strategy to enhance neuroplasticity and optimize cognitive interventions in both healthy and clinical populations.
