Masakazu Konishi

Masakazu "Mark" Konishi (小西 正一, Konishi Masakazu, born 17 February 1933) is a Japanese neurobiologist, known for his research on prey capture auditory systems of barn owls and singing in songbirds.

After growing up in wartime Kyoto, Konishi moved to study at Sapporo Agricultural College, Hokkaido University. Konishi studied for his doctoral thesis on properties of birdsong under Peter Robert Marler at University of California, Berkeley.He was elected to the National Academy of Sciences (USA) in 1985.The NAS membership directory notes that "Konishi is a world leader in linking ethology and neurophysiology. He has shown the crucial role of auditory feedback in bird songs, has elucidated the role of sound frequency and spatial characteristics in auditory localization by barn owl, and has discovered the role of hormones in early differentiation of vocal control areas in the male avian brain."
