Typically, suspended animation called near-death experiences. Scientists try to explain that experience to view the brainwaves. They found a surge of electrical activity in the brain when the victim dead faint. Spike in brain activity that is likely responsible for the near death experience. Studies conducted on mice dying found high levels of brain waves. Researchers in the U.S. say that the human experience can generate a high level of awareness. "Many people think that the brain after clinical death is not active or hypoaktif ... but this is more active during the dying process than when awake," said the head of research, told BBC Borjigin Jimo, Tuesday (13/8). Near-death experiences often reported as the sensation of bright white light out of the body as well as the feeling of life in sight. To find out about the experience, scientists at the University of Michigan watching nine rat dying. Borijin said shockwaves higher levels of brain activity and consciousness can cause a near-death vision. "The fact that they saw the light may indicate visual cortex of the brain is active high level .... because we saw an increase in gamma in the brain in the upper right area of the visual cortex," said Borjigin. ( Biasanya, mati suri disebut sebagai pengalaman mendekati kematian. Saintis cuba menjelaskan pengalaman tersebut dengan melihat gelombang otak. Mereka mendapati adanya lonjakan aktiviti elektrik di dalam otak ketika korban mati suri. Lonjakan aktiviti otak inilah yang kemungkinan bertanggungjawab terhadap pengalaman mati suri. Kajian yang dilakukan pada tikus mati mencari gelombang otak tahap tinggi. Para penyelidik di AS mengatakan pengalaman itu pada manusia dapat membangkitkan kesedaran tahap tinggi. "Banyak orang berfikir bahawa otak selepas kematian klinikal tidak aktif atau hypoaktif ... tapi ini lebih aktif semasa proses kematian berbanding saat terjaga," ujar ketua penyelidikan, Jimo Borjigin dikutip BBC, Selasa (13/8). Pengalaman mendekati kematian sering dilaporkan sebagai sensasi lampu putih terang keluar dari tubuh serta perasaan kehidupan ada di depan mata. Untuk mengetahui tentang pengalaman itu, para saintis di Universiti Michigan memantau sembilan tikus yang sedang tenat. Borijin mengatakan gelombang elektrik tahap yang lebih tinggi daripada aktiviti otak dan kesedaran boleh menimbulkan penglihatan menjelang kematian. "Hakikat bahawa mereka melihat cahaya mungkin menunjukkan penglihatan korteks pada otak sedang aktif tahap tinggi .... kerana kami melihat peningkatan gamma di kawasan otak di sebelah kanan atas dari penglihatan korteks," ungkap Borjigin. )
