### Functional Connectivity Networks  
Here, we present the functional connectivity network results for the five bands and two conditions. The results are presented as an increase in connectivity of one condition over the other (one group subtracted from the other), i.e., _'figurative'_ condition: figurative minus abstract, and _'abstract'_ condition: abstract minus figurative networks, respectively. For each band, we show the network changes at four selected time points (\(-\)300 ms/baseline/, and 100, 300 and 500 ms post-stimulus). The size of the nodes represent the relative node

strength, whereas the node colors depict the network modularity (nodes with identical colors belong to the same module). The delta band results for abstract and figurative conditions across time points are shown in Figure 6. The figurative condition shows a significant increase in node strength (size) and interconnections at 100 ms (\(p\) = 0.0259), particularly in the left occipital and parietal regions. The node strengths further increase in the 300 ms (\(p\) = 0.0273) to 500 ms (\(p\) = 0.0247) interval, showing robust connectivity across various regions (frontal, temporal and parietal areas). Conversely, the abstract condition displays increased, dense and widespread connections in the frontal and posterior areas (temporal and occipital) from 100 ms (\(p\) = 0.0239) to 300 ms (\(p\) = 0.0233), which intensifies over time. In the theta band (Figure 7), we observe the highest figurative connection increase at 500 ms (\(p\) = 0.0234), initially with frontoparietal involvement at 300 ms (\(p\) = 0.0288) that becomes more right-hemisphere-dominant with stronger frontal connections by 500 ms. In comparison, the abstract condition reveals dense, increased connectivity, earlier than that seen in the figurative condition, at 100 ms (\(p\) = 0.0223) in the frontal, right parietal and occipital regions. This connectivity density then decreases from 300 ms (\(p\) = 0.0270) to 500 ms (\(p\) = 0.0306), with a noticeable shift towards the left temporoporarietal region at 300 ms, and central and left occipital areas at 500 ms. The alpha band connectivity patterns (Figure 8) also progressed differently for both the abstract and figurative conditions. The figurative condition exhibits focused connectivity in the bilateral central regions, particularly in the left temporal area at 100 ms (\(p\) = 0.0264), progressing to denser connections in the fronto-occipital network by 300 ms (\(p\) = 0.0267), and shifting to the right frontal and posterior areas at 500 ms (\(p\) = 0.0268). The abstract condition, however, shows increased connectivity at 100 ms (\(p\) = 0.0259), with connections spanning from the occipital to frontal regions in both hemispheres. The connectivity pattern then shifts to the right hemisphere at 300 ms (\(p\) = 0.0243), involving the frontal, right temporal and left parietal areas, before becoming more distributed across the frontal, left temporal and occipital areas at 500 ms (\(p\) = 0.0269). The beta band connectivity (Figure 9) reveals significant connectivity differences across time points for both conditions. For the figurative condition, increased connectivity can be observed in the frontal and posterior regions, particularly at 100 ms (\(p\) = 0.0232) and 300 ms (\(p\) = 0.0232), with a higher beta connectivity in the frontoparietal network at 500 ms
