Hermann Munk
Hermann Munk made important contributions to the field of psychology regarding the route from the eye to the brain through his meticulous research methods.[1] In 1878, he published findings from studies involving dogs and monkeys that led to the conclusion that vision was localized in the occipital cortical area.His focus was on dogs and he, unlike many others of his time, kept his subjects alive for an average of 5 years in order to study long-term effects.While suffering from psychic blindness, dogs were able to navigate effectively but showed no sign that they recognized what the objects in front of them were when they were only allowed to use sight.The dogs normally recovered from psychic blindness in 4 to 6 weeks and did appear to relearn faster than they first learned object meanings.
