  2. Using EEG to investigate premature aging and cognitive decline in adults with Down's Syndrome

    Jennings, Sally RachelUniversity of Cambridge2017

    … (ERPs): mismatch negativity (MMN) and P300 (P3a and P3b), were chosen for exploration with cross-sectional and longitudinal investigations. The thesis begins by exploring how the ERPs differ for a cross-section of 36 adults with DS and 39 age- and gender-matched TD controls. As expected, the …

    … attentional modulation of sensory processing. A P3a-like vertex source was elicited by the loudest intensity (100 dB), but was absent for all other intensities. Insights gained from this study have direct implications for both clinical LDAEP and MMN studies. LDAEP studies should consider how …

In Experiment 4 wurde in einem Hinweisreizparadigma durch zusätzliche Stimuli eine Distraktion ausgelöst und die Nikotinwirkung auf die Reaktionszeitkosten untersucht. Nikotin zeigte keinen Einfluss auf Distraktionskosten in beiden …

Moreover, the findings indicate no age-related differential effects of acute exercise on these same indices of attention. However, absolute reaction time results indicate a significant main effect for group (F …

Populations P3a, P10 and P11 yielded two esterase bands (E2N2): one slow band, and one fast band with a migration rate largely similar to the I1 band of the M. incognita phenotype. E1bN1b and phenotypes probably represent a new species. However additional …
