Growing amounts of data indicate relationships be‑ tween resting state EEG and the cognitive functions of healthy subjects or symptoms of neurological disor‑ ders/dysfunctions in clinical investigations. To inves‑ tigate these correlations we designed an experiment in which participants were grouped on the basis of their resting state EEG spectral power and tested for differ‑ ences in event related potentials and behavioural per‑ formance during repeated tasks addressing attention processes. 33 healthy adults were tested twice (TEST and RETEST, two months apart) with top-down and bot‑ tom-up visual attention tasks. EEG was recorded during tasks and preceding resting state sessions. Analyses in‑ cluded: correlation between reaction times (RTs) and resting state EEG powers in theta, alpha, beta 1, and beta 2 bands, and two-way ANOVA analysis of the RTs and amplitudes of contingent negative variation (CNV) in TEST and RETEST of the two subgroups defined by highest and lowest resting state amplitudes. Only the beta 2 band power correlated with RTs measured in top-down and bottom-up attention tasks. Subjects with the lowest beta 2 resting state amplitudes were char‑ acterized by shortening of RTs and increasing ampli‑ tudes of the CNV wave in RETEST as compared to TEST. These findings posit a link between individual resting state brain activity in the beta 2 range and susceptibil‑ ity to long-term changes in the functional processing of visual stimuli.
