Can a dead brain think and react to external stimuli? Until now, this possibility had been the realm of science fiction and horror movies. However, a recent peer-reviewed study has shown that brains which had been preserved in formaldehyde and alcohol for as long as twenty years after they had been removed from their body, still reacted to external stimuli in much the same way a living brain would. What’s more, these pickled brains showed cerebral activity nearly identical to that of living brains in the area of the brain most associated with personality, a sense of self, and core memories, which suggests the perseverance of some residue of the person deep inside a disembodied brain.

मृत मस्तिष्क को लगता है और बाहरी उत्तेजनाओं पर प्रतिक्रिया कर सकता है? अब तक, यह संभावना विज्ञान कथा और हॉरर फिल्मों का क्षेत्र रहा था। हालांकि, एक हालिया सहकर्मी की समीक्षा में यह पता चला है कि जिन दिमागों को फार्मलडिहाइड और अल्कोहल में संरक्षित किया गया था, उनके शरीर से निकाले जाने के करीब 20 साल बाद भी, बाहरी उत्तेजनाओं के बारे में अभी भी एक जीवित मस्तिष्क की तरह प्रतिक्रिया व्यक्त की गई थी। क्या अधिक है, इन मसालेदार मस्तिष्क ने मस्तिष्क की गतिविधि को व्यक्त किया, जो व्यक्तित्व, स्वयं की भावना, और मूल यादों से जुड़े मस्तिष्क के क्षेत्र में रहने वाले दिमागों के समान ही थे, जो बताता है कि एक अस्थिरता के अंदर के व्यक्ति के कुछ अवशेषों की धीरज दिमाग।
