The person I admire is: Aleksandr Lúriy

Alexander Romanovich Luria (16 July 1902 – 14 August 1977) was a Soviet neuropsychologist and developmental psychologist. He was one of the founders of Cultural-Historical Psychology, and a leader of the Vygotsky Circle, also known as "Vygotsky-Luria Circle". Luria's magnum opus is Higher Cortical Functions in Man (1962), a psychological textbook which has been translated into many languages and which he supplemented with The Working Brain in 1973. Apart from his work with Vygotsky, Luria is widely known for two extraordinary psychological case studies: The Mind of a Mnemonist, about Solomon Shereshevsky, who had highly advanced memory; and The Man with a Shattered World, about a man with traumatic brain injury. In addition Luria describes all mental activity based on three functional units of the brain:
1) Unit to regulate the tone or wakefulness. 2) Unit to obtain, process and store information that comes from the outside world. 3) Unit to program, regulate and verify mental activity is the organization of conscious activity.
I admire this person for perseverance in his work, he devoted his life to the understanding and explanation of one of the most serious human problems, that of the deficits of the superior capacities of man caused by the affections of the brain, and therefore to the explanation of brain activity itself.
