Alzheimer’s Researchers Research a Uncommon Mind

Whereas they waited for Aliria’s physique to reach, Dr. Villegas and the workers messaged one another calls for: freezers checked, sterile gloves, iodine, cell tradition medium, tissue preservative blended and prepared. The mind financial institution usually sends tissue to its collaborators overseas, and inside days samples of Aliria’s mind can be below research in Germany and California, in addition to Medellín.

Every mind donation begins not in a hospital mortuary however in a big and well-equipped funeral residence. The association permits the researchers to take away the mind and stroll it shortly to their dissection lab a block away, after which the household can proceed with a funeral or cremation.

Aliria’s post-mortem began at 11:30 a.m., three hours after her demise. Dr. Villegas’s senior staff members, Dr. Aguillon and Johana Gómez, a biologist, suited up in plastic overalls, masks and face shields, precautions made vital by the pandemic, whereas a medical scholar, Carlos Rueda, stood by taking notes.

The staff eliminated the mind with relative ease, though the method is at all times intricate, with connective tissue that should be fastidiously severed. Dr. Villegas then extracted from deeper within the cranium the pituitary gland and olfactory membrane, buildings of curiosity to Alzheimer’s researchers. The group took samples of pores and skin, tumor and important organs, earlier than leaving the stays of their well-known affected person, one on whom so many analysis hopes have been pinned, to be cremated.

Inside minutes the group converged once more down the road on the mind financial institution’s dissection lab, a room no larger than a walk-in closet. It was almost 1 p.m., and Dr. Aguillon positioned Aliria’s mind on a scale. It weighed 894 grams, just below two kilos — significantly lower than a wholesome mind. Mr. Rueda started photographing it on a rotating platform used to create a three-dimensional picture, whereas Dr. Villegas narrated and Dr. Aguillon typed.
