我们为何做梦？从神经科学到精神世界的奇妙之旅

Group 1 - The exploration of dreams has evolved from ancient beliefs to modern neuroscience, indicating that dreams may have significant connections to human thought, memory, and creativity [1][3][17] - REM sleep, discovered in 1953, is characterized by high brain activity similar to wakefulness, where most vivid dreams occur [3][4][6] - Dreams are not random; they are closely linked to daily experiences, emotions, and memories, facilitated by the brain's complex neural networks, particularly the Default Mode Network (DMN) [11][12][13] Group 2 - During REM sleep, the brain processes and reorganizes memories, often amplifying emotional experiences, which explains the intense feelings associated with dreams [12][13] - The brain's activity during REM sleep involves various regions, such as the visual cortex for imagery and the limbic system for emotions, while the prefrontal cortex's activity is suppressed, leading to illogical dream narratives [9][10][11] - Dreams may serve as a means of emotional regulation, helping individuals cope with stress and anxiety by reprocessing emotional memories [12][13] Group 3 - The similarities between dreams and hallucinations suggest a shared neurobiological basis, particularly in conditions like schizophrenia, where individuals may struggle to distinguish between reality and their internal perceptions [14][15] - Lucid dreaming, where individuals maintain self-awareness, may offer therapeutic potential for those experiencing hallucinations, allowing them to better control their experiences [16] - The ongoing research into dreams not only seeks to unravel their mysteries but also aims to address fundamental questions about consciousness and reality [17]
