Non-Linear Dorsolateral Prefrontal Recruitment During Speech-in-Noise Perception in Aging
Age-related speech-in-noise difficulties have been associated with increased activity in prefrontal regions. Whether this upregulation reflects adaptive compensation, neural inefficiency, or changes in task engagement as listening demands increase remains unresolved. Most studies have relied on linear contrasts of task difficulty, limiting our understanding of how the role of prefrontal…
