  • Changes in event-related potentials during dual task walking . . .
    Significant task by group interaction was found in P300 amplitude (p = 0 008) Patients with PD demonstrated reduced P300 amplitude during walking compared to standing (p = 0 023) Among all subjects, better motor and cognitive performance correlated with shorter P300 latency (r = 0 457, p = 0 014 and r = 0 431, p = 0 040, respectively)
  • On the relationship between EEG and P300: individual . . .
    The effects of EEG activity on sensory evoked potentials (EPs) have been investigated in various studies In general, comparisons between background EEG and EP values have been made either by: (1) recording EEG in groups of individuals — sometimes selected for special characteristics (e g , low vs high alpha power) — and assessing how EEG variability affects EP amplitude and latency
  • Impaired Inhibitory Control During Walking in Parkinson’s . . .
    However, no differences between sitting and walking were observed, demonstrating that late processing stages of inhibitory control are less sensitive to dual task load These results are not in line with studies that showed small reduction in P300 amplitude during walking [17, 33] These discrepancies may relate to the differences in the
  • Changes in the EEG spectral power during dual-task walking . . .
    A previous study by Malcolm et al also demonstrated differences between young and older adults during dual-task walking but only in P300 latency and amplitude In patients with PD, comparison between single and dual tasks revealed early reduction in delta and theta power followed by late increase in beta power during dual-task walking
  • Physical activity modulates inhibitory control: EEG insights . . .
    The results revealed a significant group effect on the average P300 amplitude at the relevant electrodes P300 is a well-studied, stimulus-locked component whose amplitude reflects the amount of attentional resources allocated to a specific task In the current study, during the flanker task, the amplitude of P300 was significantly higher in
  • Event-related modulation of alpha rhythm explains the . . . - eLife
    The proportion of correlation between P300 latency and attention, mediated by alpha attenuation peak latency, is 0 12 Memory scores were positively related to P300 amplitude and negatively to P300 latency (Figure 7A, middle column) The direction of correlation is such that higher memory scores, which reflected more recalled items
  • Synchronisation Issues in Wireless EEG Systems for P300 . . .
    New wireless devices allow EEG acquisition during walking and support the investigation on the relationship between cognition and movement In particular, P300 is a positive deflection in the EEG signal occurring approximately 300 ms after a stimulus recognition P300 is demonstrated to be useful in the detection of cognitive state and in the diagnosis of several neurodegenerative disorders
