Ionete da Silveira Gama, o Dona Onete, es conocida como la diva del "carimbó chamegado", un ritmo de su propia creación que combina la música tradicional de Pará, en el norte de Brasil, con "un poco de picante", como ella dice.
Dona Onete empezó a cantar desde niña pero su carrera musical no despegó hasta que estuvo en sus 70, cuando un conjunto local la escuchó por casualidad.
Su primer álbum discográfico, Feitiço Caboclo o "El encanto del caboclo", se grabó en 2012 cuando tenía 73 años. Caboclo es una expresión común para decir indígena, y el álbum refleja la pasión de que siente Onete por sus diversas raíces rurales y étnicas.

Abstract
What explains the superior cognitive abilities of the human brain compared to other, larger brains? Here we investigate the possibility that the human brain has a larger number of neurons than even larger brains by determining the cellular composition of the brain of the African elephant. We find that the African elephant brain, which is about three times larger than the human brain, contains 257 billion (10(9)) neurons, three times more than the average human brain; however, 97.5% of the neurons in the elephant brain (251 billion) are found in the cerebellum. This makes the elephant an outlier in regard to the number of cerebellar neurons compared to other mammals, which might be related to sensorimotor specializations. In contrast, the elephant cerebral cortex, which has twice the mass of the human cerebral cortex, holds only 5.6 billion neurons, about one third of the number of neurons found in the human cerebral cortex. This finding supports the hypothesis that the larger absolute number of neurons in the human cerebral cortex (but not in the whole brain) is correlated with the superior cognitive abilities of humans compared to elephants and other large-brained mammals.
