What do these measures reveal?

In MCI patients, increased beta-band connectivity suggests improved communication between distant brain areas, especially in networks like the:

1) Default Mode Network (DMN) – self-referential thought
2)Dorsal Attention Network (DAN) – attention and visual tracking
3)Sensorimotor Network (SMN) – motor planning and coordination

In healthy adults, sustained increases in alpha and beta power 1 year after training reflect long-lasting neuroplasticity, especially in parietal and occipital lobes—areas linked to memory consolidation and visuospatial awareness.
