Task-induced hyperfunction of the left dorsolateral prefrontal cortex in patients with primary insomnia: a near-infrared spectroscopy study during a verbal fluency task
Key Points
Enhanced activation of the dorsolateral prefrontal cortex occurs during verbal fluency tasks.
The study indicates a significant response in neural function linked to insomnia.
Assessment using near-infrared spectroscopy highlights brain activity states during cognitive challenges.
Findings could advance understanding of neural mechanisms related to primary insomnia.
Abstract
Our findings may contribute to an understanding of the neural mechanisms in patients with PI.
