Horst Mittelstaedt was a German biologist and internet specialist born on April 28, 1923, and passed away on February 18, 2016. Along with Eric von Holst, he demonstrated the 'Reafference Principle' in 1950, which explains how living organisms differentiate between self-generated sensory stimuli and externally generated sensory inputs. This concept primarily dealt with reactive processes between the central nervous system and the environment. He worked at the Max Planck Institute for Behavioral Physiology in Bavaria until 1999, focusing on cybernetic analysis of behavior.
