Benjamin Libet

Benjamin Libet (/ˈlɪbət/;[1] April 12, 1916 – July 23, 2007) was an American neuroscientist who was a pioneer in the field of human consciousness. Libet was a researcher in the physiology department of the University of California, San Francisco. In 2003, he was the first recipient of the Virtual Nobel Prize in Psychology from the University of Klagenfurt, "for his pioneering achievements in the experimental investigation of consciousness, initiation of action, and free will".[2]

He was the son of Ukrainian Jewish immigrants. Gamer Libitsky, his paternal grandfather, came to America in 1865 from a town called Brusilov in Ukraine. His mother, Anna Charovsky, emigrated from Kiev in 1913. His parents first met in Chicago. They were married in 1915, and somewhat over nine months later Benjamin was born. He had a brother Meyer, and a sister Dorothy. Libet attended a public elementary school and John Marshall High School. In 1939, Libet graduated from the University of Chicago, where he studi…more

He had a brother Meyer, and a sister Dorothy. Libet attended a public elementary school and John Marshall High School. In 1939, Libet graduated from the University of Chicago, where he studied with Ralph W. Gerard.[3]

In the 1970s, Libet was involved in research into neural activity and sensation thresholds. His initial investigations involved determining how much activation at specific sites in the brain was required to trigger artificial somatic sensations, relying on routine psychophysical procedures. This work soon crossed into an investigation into human consciousness; his most famous experiment was meant to demonstrate that the unconscious electrical processes in the brain called Bereitschaftspotential (or readiness potential) discovered by Lüder Deecke and Hans Helmut Kornhuber in 1965[4] precede conscious decisions to perform volitional, spontaneous acts, implying that unconscious neuronal processes precede and potentially cause volitional acts which are retrospectively felt to be consciously motivated by the subject. The experiment has caused controversy not only because it challenges the belief in free will, but also due to a criticism of its implicit assumptions.[5]
