| الوصف: | High-gamma frequency flashes can enhance cognition by synchronizing neural oscillations in mammals. Early flash treatment promotes the development of improved cognitive functions in young children. However, it is unclear whether exposure to high-gamma frequency flashes in preschool-aged individuals affects cognition in preadolescents by regulating neural oscillations in the brain. Here, we aimed to investigate the effects of gamma-frequency flashes on cognitive ability. In this study, the effect of high-frequency flicker on cognitive performance was verified by behavioural experiments such as the open-field test and the water maze, but also proteomics. We found that external 40 Hz and 70 Hz frequency flashes synchronized neural oscillations at the corresponding frequencies in the primary visual cortex (V1) of rats. Rats that underwent 70 Hz flash intervention had better cognitive behavioural performance in the early stages of training. The 70 Hz flash frequency upregulated proteins associated with neuronal growth and differentiation, such as Snapin, FoxO3, Hspa12a, and Penk, and activated the MAPK signalling pathway, signalling pathway regulating stem cell pluripotency, and the neuroactive ligand-receptor interaction pathway. These proteins and pathways play important roles in cognitive functions. Our study revealed that 70 Hz flashes received by young children early in their development substantially promote the growth of cognitive capabilities in the brain. Exposure to 70 Hz flashes may be a new intervention method and a new strategy for improving cognition. |
