Highlights ■ Pre-sarcopenic women showed increased cortical excitation during motor tasks. ■ Sarcopenia was associated with slower motor reaction time. ■ EEG revealed central nervous system changes across sarcopenia stages. ■ Pre-sarcopenia may represent a window for early neuromotor intervention. ABSTRACT Objective: This study aimed to analyze cortical activity during simple motor reaction time tasks in older women with different degrees of sarcopenia. Methods: This cross-sectional, observational, analytical study included 59 women classified into control, pre-sarcopenia, and sarcopenia groups according […]

ABSTRACT Objective To assess changes in blood-oxygen-level-dependent activity after light deprivation compared to regular light exposure in subjects with migraine in the interictal state and in controls. Methods Ten subjects with migraine and ten controls participated in two sessions of functional magnetic resonance imaging. In each session, they performed a finger-tapping task with the right hand, cued by visual stimuli. They were scanned before and after 30 minutes of light deprivation or light exposure. In subjects with migraine, functional magnetic […]
