Motor reaction time in older women with different degrees of sarcopenia: What do electroencephalograms show?
DOI: 10.31744/einstein_journal/2026AO1541
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 […]

Analysis of electroencephalography brain rhythms in the reading process
DOI: 10.31744/einstein_journal/2020AO5442
ABSTRACT Objective: To verify if, by three distinct quantifiers, the measured electroencephalographic signal at rest is different from the signal measured during a word reading situation, especially considering the faster rhythms, gamma and high-gamma, as it occurs in clinical rhythms (delta to beta). Methods: A total of 96 electroencephalographic signals measured from neurologically healthy volunteers were evaluated at two moments: resting and word reading. Each signal segment was measured by three quantifiers that separately assess normalized power, percent power, and […]
